Compile and Execute a Program
1. Compile Pay.java using the JDK or a Java IDE as directed by your instructor.
2. You should not receive any error messages.
3. When this program is executed, it will ask the user for input. You should calculate several different cases by hand. Since there is a critical point at which the calculation changes, you should test three different cases: the critical point, a number above the critical point, and a number below the critical point. You want to calculate by hand so that you can check the logic of the program. Fill in the chart below with your test cases and the result you get when calculating by hand.
4. Execute the program using your first set of data.
Record your result. You will need to execute the program three times to test all your data. Note: you do not need to compile again. Once the program compiles correctly once, it can be executed many times. You only need to compile again if you make changes to the code. Hours Rate Pay (hand calculated) Pay (program result) LLLLLLLLLL import java.util.Scanner; // Needed for the Scanner class This program calculates the user's gross pay. public class Pay public static void main(String[] args) // Create a Scanner object to read from the keyboard. Scanner keyboard = new Scanner(System.in); // Identifier declarations double hours; // Number of hours worked double rate; // Hourly pay rate double pay; // Gross pay // Display prompts and get input. System.out.print("How many hours did you work? "); hours = keyboard.nextDouble(); System.out.print("How much are you paid per hour? "); rate - keyboard.nextDouble(); // Perform the calculations. if (hours <- 40) pay - hours * rate; else pay - (hours - 40) - (1.5 * rate) + 40 - rate; // Display results. System.out.println("You earned $" + pay);
Answer:
import java.util.Scanner;
// Needed for the Scanner class This program calculates the user's gross pay.
public class Pay {
public static void main(String[] args) {
// Create a Scanner object to read from the keyboard.
Scanner keyboard = new Scanner(System.in);
// Identifier declarations

// Gross pay
// Display prompts and get input.
System.out.print("How many hours did you work? ");
hours = keyboard.nextDouble();
System.out.print("How much are you paid per hour? ");
rate = keyboard.nextDouble();
// Perform the calculations.
if (hours <= 40) {
pay = hours * rate;
}
else
{
pay = (hours - 40) - (1.5 * rate) + 40 - rate;
}
// Display results.
System.out.println("You earned $" + pay);

Ask the user to input a country name. Display the output the message “I
would love to go to [country]”
Answer:
Explanation:
The following code is written in Python, it asks the user for an input saves it to a variable called country, and then prints out the sentence example in the question using the user's input. The output can be seen in the picture attached below
country = input("input country")
print('I would love to go to ' + country)
In this problem, you should write one function named count_calories. This function should have one parameter, which will be a dictionary of food items. The keys will ne the name of a food item (such as 'granola' or 'steak'), and the value associated with each food will be the integer calorie amount for that food. The function should iterate through all of the foods and sum up the total calories, and then return that number. For example:
count_calories({'chocolate':200, 'milk':120, 'steak':250}) should return 570.
count_calories({'carrot':5, 'apple':50}) should return 55.
Make sure to include only the one function in your file.
Answer:
The function is as follows:
def count_calories(dictt):
total = 0
for keys, values in dictt.items():
total+=values
return total
Explanation:
This defines the function
def count_calories(dictt):
This initializes total to 0
total = 0
This iterates through the dictionary
for keys, values in dictt.items():
This adds the dictionary
total+=values
This returns the calculated total
return total
Write a function named word_beginnings that has two parameters line a string ch a character Return a count of words in line that start with ch. For the purposes of this exercise a word is preceeded by a space. Hint: add a space to the beginning of line For example if line is 'row row row your raft' and ch is 'r' the value 4 will be returned. Note: You can use lists in this question but try to solve it without lists.
Answer:
The function in Python is as follows:
def word_beginnings(line, ch):
count = 0
lines =line.split(" ")
for word in lines:
if word[0] == ch:
count+=1
return count
Explanation:
This defines the function
def word_beginnings(line, ch):
This initializes count to 0
count = 0
This splits line into several words
lines =line.split(" ")
This iterates through each word
for word in lines:
This checks if the first letter of each word is ch
if word[0] == ch:
If yes, increment count by 1
count+=1
Return count
return count

Manny has drafted an email message and configured a delivery option “Do not delivery before 5:00 PM and today’s date” he shuts down his computer and leaves for the day at 4:30 pm. What will happen at 5 pm?
- the message will be delivered from the server
- the message will be delivered from Manny’s computer
- the message will remain in manny’s outbox until the computer is started and the outlook programs is started the next day
- the message will remain in Manny’s outbox until the computer is started and he will be promoted
Answer:
Explanation:
In this scenario, the message will remain in manny’s outbox until the computer is started and the outlook programs is started the next day. When you create a message but do not send it, even if you schedule to send it, the message gets saved as a draft in your outbox. Once the scheduled time arrives the program will grab the message, prepare it, and send it. This will however not happen if the program is closed. Therefore, Manny's message will only send once the computer is turned on and the Outlook program relaunches.
When adding delegates to his mailbox, which role should Joel use if he would like the user to be able to read and create items in a particular folder?
- editor
- publishing editor
- author
- manager
Answer:
publishing editor
Explanation:
In this scenario, the role that he should choose for the delegates would be publishing editor. This role will allow them to create, read, modify, and delete all items within a given folder, and create subfolders. The other options listed either do not give access to create/modify existing files or simply only give all these rights with files that the user creates but not files that already existed in the folder. Therefore, this would be the best role for what Joel wants to accomplish.

1. What are the main features of IEEE 802.3 Ethernet standard?
Answer:
Single byte node address unique only to individual network. 10 Mbit/s (1.25 MB/s) over thick coax. Frames have a Type field. This frame format is used on all forms of Ethernet by protocols in the Internet protocol suite.
Explanation:
802.3 is a standard specification for Ethernet, a method of packet-based physical communication in a local area network (LAN), which is maintained by the Institute of Electrical and Electronics Engineers (IEEE). In general, 802.3 specifies the physical media and the working characteristics of Ethernet.

Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 12-character telephone number in the format: XXX-XXX-XXXX. Acceptable characters (X's) are A-Z and a-z. Your program should check for: The length of the phone number is correct. The dashes are included and are in the correct positions. There are no characters in the illegal characters in the string. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. If the input string is not entirely correct then you should print an error message. For example, if the user enters 555-GET-FOOD the program should display 555-438-3663. If the user enters 123-456-7890, the program should display 123-456-7890. Rules: You must have one function (in addition to main()) that converts an alphabetic character to a digit. Or you can have one function that coverts all characters to digits. You can make your own function or use a built-in function if one exists.
Answer:
The program in Python is as follows:
def convertt(phone):
splitnum = phone.split ('-')
valid = True
count = 0
err = ""
numphone = ""
if len(phone) != 12:
err = "Invalid Length"
valid = False
elif phone[3] != '-' or phone[7] != '-':
err = "Invalid dash [-] location"
valid = False
while valid== True and count < 3:
for ch in splitnum[count]:
if ch.isdigit():
numphone += ch
elif ch.upper()in 'ABC':
numphone += '2'
elif ch.upper()in 'DEF':
numphone += '3'
elif ch.upper()in 'GHI':
numphone += '4'
elif ch.upper() in 'JKL':
numphone += '5'
elif ch.upper()in 'MNO':
numphone += '6'
elif ch.upper()in 'PQRS':
numphone += '7'
elif ch.upper()in 'TUV':
numphone += '8'
elif ch.upper()in 'WXYZ':
numphone += '9'
else:
valid = False
err = "Illegal character in phone number"
if count!=2:
numphone += '-'
count += 1
if valid == False:
print (err)
else:
print ("Phone Number", numphone)
phone = input("Phone number: ")
convertt(phone)

False
This is absolutely true. A shining example of this is with smartphones. Before Apple introduced the world to the iPhone, most smartphones had actual keyboards, zero touchscreen capabilities, could barely browse the internet, and had very small displays. After the iPhone was released in 2007, companies immediately scrambled to come out with phones that looked uncannily similar to Apple's. Why? Because Apple's phone was designed well. It's pretty amazing how immediate the shift was. In fact, I recomend you look up "Smartphones before and after iPhone" online. It's pretty cool. Here's an image example: https://www.redmondpie.com/image-showing-phones-before-and-after-iphone-x-revisits-how-android-market-still-tends-to-copy-iphone/

Explanation:
Consider the following incomplete method. Method findNext is intended to return the index of the first occurrence of the value val beyond the position start in array arr. I returns index of first occurrence of val in arr /! after position start; // returns arr.length if val is not found public int findNext (int[] arr, int val, int start) int pos = start + 1; while condition '/ ) pos++ return pos; For example, consider the following code segment. int [ ] arr {11, 22, 100, 33, 100, 11, 44, 100); System.out.println(findNext (arr, 100, 2)) The execution of the code segment should result in the value 4 being printed Which of the following expressions could be used to replace /* condition */ so that findNext will work as intended?
(A) (posarr.length) &&(arr [pos]- val)
(B) (arr [pos] != val) && (pos < arr. Îength)
(C) (pos
(D) (arr [pos} == val) && (pos < arr. length)
(E) (pos
Answer:
B)
Explanation:
The while loop runs as long as two conditions are satisfied, as indicated by the && logical operator.
The first condition- arr[pos] != val
checks to see if the value in the array index, pos, is equal to the given value and while it is not equal to it, the second condition is checked.
The second condition(pos < are.length), checks to see if the index(pos) is less than the length of the array. If both conditions are true, the program execution enters the while loop.
The while loop is only terminated once arr[pos] == Val or pos == arr.length.
Use the web to learn how to use the LocalDate Boolean methods isBefore(), isAfter(), and equals(). Use your knowledge to write a program that prompts a user for a month, day, and year, and then displays a message specifying whether the entered day is in the past, is today (the current date), or is in the future.
import java.util.*;
import java.time.LocalDate;
public class PastPresentFuture2
{
public static void main(String args[])
{
int mo,da,yr;
LocalDate today=LocalDate.now();
System.out.println("Program to find if the given date is in past, present or future::");
Scanner input=new Scanner(System.in);
//taking inputs from console and storing them in three variables.
System.out.print("Enter month::");
mo=input.nextInt();
System.out.print("Enter day::");
da=input.nextInt();
System.out.print("Enter year::");
yr=input.nextInt();
//creating a LocalDate object and initializing it to null;
LocalDate inputDate=null;
try
{
/*we are using the 3 variables and converting it into a date object to compare it with today's date */
inputDate = LocalDate.of(yr,mo,da);
}
catch(Exception ex)
{
/*if the entered day,month & year are not converted to a date object because of invalid entry of any values, we are stopping the program.*/
System.out.println("You have made invalid entries, please try again !!");
System.exit(0);
}
/*if the date object is created after proper entries, we are using the built-in functions to compare it the today's date object*/
System.out.print("The date you entered is ");
if(inputDate.isBefore(today))
System.out.println("in the past.");
else
if(inputDate.isAfter(today))
System.out.println("in the future.");
else
if(inputDate.equals(today))
System.out.println("the current date.");
}
}
Answer:
Explanation:
The code provided is already taking in the input and comparing it to the current date using the methods isBefore(), isAfter(), and equals(). It works perfectly and did not need any changes to the code. As you can see from the attached pictures below, every scenario works as intended. If the format is not correct and the date object is not able to be created then it prompts an error message and exits the program as intended.
import java.util.*;
import java.time.LocalDate;
class PastPresentFuture2
{
public static void main(String args[])
{
int mo,da,yr;
LocalDate today=LocalDate.now();
System.out.println("Program to find if the given date is in past, present or future::");
Scanner input=new Scanner(System.in);
//taking inputs from console and storing them in three variables.
System.out.print("Enter month::");
mo=input.nextInt();
System.out.print("Enter day::");
da=input.nextInt();
System.out.print("Enter year::");
yr=input.nextInt();
//creating a LocalDate object and initializing it to null;
LocalDate inputDate=null;
try
{
/*we are using the 3 variables and converting it into a date object to compare it with today's date */
inputDate = LocalDate.of(yr,mo,da);
}
catch(Exception ex)
{
/*if the entered day,month & year are not converted to a date object because of invalid entry of any values, we are stopping the program.*/
System.out.println("You have made invalid entries, please try again !!");
System.exit(0);
}
/*if the date object is created after proper entries, we are using the built-in functions to compare it the today's date object*/
System.out.print("The date you entered is ");
if(inputDate.isBefore(today))
System.out.println("in the past.");
else
if(inputDate.isAfter(today))
System.out.println("in the future.");

Explanation:
in cell B5 create a formula using round function that rounds the value in cell G19 to an integer, with 0 decimal places
Answer:
=ROUND(G19, 0)
Explanation:
In Microsoft Excel you would need to click on cell B5 and then click the function bar at the top and paste the following formula
=ROUND(G19, 0)
This formula will grab whatever value is in cell G19 and round it to the nearest whole integer without any decimal places at all. This is handled by the ROUND() method which takes in two arguments, the first is the cell which has the value to be rounded, and the second argument is the number of decimal places to round to. 0 indicates no decimal places.

HLOOKUP is used for Horizontal Data look ups while VLOOKUP is for Vertical Data look ups
Select one:
True
False
Answer:
True
Explanation:
Both HLOOKUP and VLOOKUP are excel functions used for searching through tables for a specified lookup value to either get an exact or approximate match. The VLOOK and HLOOKUP functions have identical syntax which only differs with the HLOOKUP requiring the row index number to search through the rows while, VLOOKUP requires the column index number to search through the columns. Other than this difference, the other syntax values are the same.
VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])

How is an interpreter different from a compiler?
An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.
An interpreter translates all code at once so that it is ready to be executed at any time, while a compiler translates and executes code line by line.
An interpreter translates programming code into binary language, while a compiler does not.
An interpreter translates binary language into programming language, while a compiler translates programming language into binary language.
Answer:
An interpreter is quite different from a complier due to the following statement below:
O. An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.
Explanation:
For an interpreter, it works in translating and execution of the codes line after another line. In a situation where there is a mistake in the code, the next line would not be able to be executed, but rather display error message. On the other hand, compiler translate all codes at once and execute them as a single work.
During its translation of the codes in compiler, should there be any error, it would not be able to execute despite the fact that, the error might be in the last line of the code.
