What does the following code print?
public class { public static void main(String[] args) { int x=5 ,y = 10; if (x>5 && y>=2) System.out.println("Class 1"); else if (x<14 || y>5) System.out.println(" Class 2"); else System.out.println(" Class 3"); }// end of main } // end of class.
Answer:
It throws an error.
the public class needs a name.
like this:
public class G{ public static void main(String[] args) {
int x=5 , y = 10;
if (x>5 && y>=2) System.out.println("Class 1");
else if (x<14 || y>5) System.out.println(" Class 2");
else System.out.println(" Class 3"); }// end of main
}
if you give the class a name and format it, you get:
Class 2
Explanation:
Suppose that you are asked to modify the Stack class to add a new operation max() that returns the current maximum of the stack comparable objects. Assume that pop and push operations are currently implemented using array a as follows, where item is a String and n is the size of the stack. Note: if x andy are objects of the same type, use x.compareTo(y) to compare the objects x and y public void push String item ) { [n++] = iten; } public String pop { return al--n]; } Implement the max operation in two ways, by writing a new method using array a (in 8.1), or updating push and pop methods to track max as the stack is changed (in 8.2). Q8.1 Implement method maxi 5 Points Write a method max() using Out) space and Oin) running time. public String max() {...} Enter your answer here Q8.2 Update push() and popo 5 Points Write a method max() using On) space and 011) run time. You may update the push and pop methods as needed public void push {...} public String pop() {...} public String max() {...}
Answer:
Following are the code to the given points:
Explanation:
For point 8.1:
public String max()//defining a method max
{
String maxVal=null;//defining a string variable that holds a value
for(int x=0;x<n;x++)
{
if(maxVal==null || a[i].compareTo(maxVal)>0)//defining if blok to comare the value
{
maxVal=a[i];//holding value in maxVal variable
}
}
return maxVal;//return maxVal variable value
}
For point 8.2:
public void push(String item)//defining a method push that accepts item value in a parameter
{
a[n]=item;//defining an array to hold item value
if(n==0 || item.compareTo(maxVals[n-1])>0)//use if to comare item value
{
maxVals[n]=item;//holding item value in maxVals variable
}
else
{
maxVals[n]=maxVals[n-1];//decreasing the maxVals value
}
n++;//incrementing n value
}
public String pop()//defining a method pop
{
return a[--n];//use return value
}
public String max()//defining a method max
{
return maxVals[n-1];//return max value
}
In the first point, the max method is declared that compares the string and returns its max value.In the second point, the push, pop, and max method are declared that works with their respective names like insert, remove and find max and after that, they return its value.Consider the following statements. An abstract class is better than an interface when the variables in the abstract class or interface are likely to have changing values. An interface is better than an abstract class when nearly all of the methods in the abstract class or interface are abstract. An abstract class is better than an interface if new methods are likely to be required in the abstract class or interface in the future. An abstract class is better than an interface if a sub class is likely to need to inherit more than one super class. Which of the choices below is correct?

Explanation:
In the following cell, we've loaded the text of Pride and Prejudice by Jane Austen, split it into individual words, and stored these words in an array p_and_p_words. Using a for loop, assign longer_than_five to the number of words in the novel that are more than 5 letters long. Hint: You can find the number of letters in a word with the len function.
Answer:
Explanation:
Since the array is not provided, I created a Python function that takes in the array and loops through it counting all of the words that are longer than 5. Then it returns the variable longer_than_five. To test this function I created an array of words based on the synapse of Pride and Prejudice. The output can be seen in the attached picture below.
def countWords(p_and_p_words):
longer_than_five = 0
for word in p_and_p_words:
if len(word) > 5:
longer_than_five += 1
return longer_than_five
Using a loop and indexed addressing, write code that rotates the members of a 32-bit integer array forward one position. The value at the end of the array must wrap around to the ?rst position. For example, the array [10,20,30,40] would be transformed into [40,10,20,30].
//begin class definition
public class Rotator{
//main method to execute the program
public static void main(String []args){
//create and initialize an array with hypothetical values
int [] arr = {10, 20, 30, 40};
//create a new array that will hold the rotated values
//it should have the same length as the original array
int [] new_arr = new int[arr.length];
//loop through the original array up until the
//penultimate value which is given by 'arr.length - 1'
for(int i = 0; i < arr.length - 1; i++ ){
//at each cycle, put the element of the
//original array into the new array
//one index higher than its index in the
//original array.
new_arr[i + 1] = arr[i];
}
//Now put the last element of the original array
//into the zeroth index of the new array
new_arr[0] = arr[arr.length - 1];
//print out the new array in a nice format
System.out.print("[ ");
for(int j = 0; j < new_arr.length; j++){
System.out.print(new_arr[j] + " ");
}
System.out.print("]");
}
}

Construct a SQL query that displays a list of colleges, their sity/state, the accrediting agency, and whether or not the school is distance only. Only show the first 10 records.
Answer:
SELECT college, city_state, accre_agency, distance LIMIT 10
Explanation:
Given
Table name: College
See attachment for table
Required
Retrieve top 10 college, state, agency and school distance from the table
To retrieve from a table, we make use of the SELECT query
The select statement is then followed by the columns to be selected (separated by comma (,))
So, we have:
SELECT college, city_state, accre_agency, distance
From the question, we are to select only first 10 records.
This is achieved using the LIMIT clause
i.e. LIMIT 10 for first 10
So, the complete query is:
SELECT college, city_state, accre_agency, distance LIMIT 10

The moment that S-locks are released will determine:__________
a. The granularity of locks
b. The compliance with ACID
c. The look-ahead logging strategy
d. The anomalies that can happen
Answer:
A.
Explanation:
In computer science, the selection of a lockable device is an essential consideration in the creation of a database management system.
Granularity locking is a locking technique that is applied in database management systems (DBMS) as well as relational databases. The granularity of locks corresponds to how much data is locked at once, and it is determined when S lock (Shared Locks) are released.
The moment that S-locks are released will determine the granularity of locks (Option a).
A lock can be defined as a procedure capable of enforcing limits on access to a particular resource when there exist many threads of execution.Multiple granularity locking (abbreviated as MGL) is a locking strategy employed in database management systems and also in relational databases. This strategy (multiple granularity locking) is often used in order to ensure serializability.In conclusion, the moment that S-locks are released will determine the granularity of locks (Option a).

A database designer wants to create three tables: Supplier, Product, and Country. The Supplier table has a Countryld column with values that must appear in the Country table's Countryld column. The Product table has an auto-increment column.
Which table's CREATE TABLE statement(s) must specify a FOREIGN KEY?
a. Supplier
b. Product
c. Country
d. Supplier and Country
Answer:
(a) Supplier
Explanation:
In database design, two tables are linked together using a FOREIGN KEY. A foreign key is formed from one or more columns of one table that reference or match another key (often called a primary key) in another table. In other words, when a column or a combination of columns on one table points to a primary key of another table, the column(s) will specify the foreign key.
PS: A primary key is used to make each entry of a table unique.
In the given tables - Supplier, Product, Country - since the Supplier table has a column called CountryId referencing the CountryId column of the Country table, then CountryId is a primary key in Country table but a foreign key in Supplier table.
Therefore, the CREATE TABLE statement(s) of the Supplier table must specify a foreign key.
A database management system often reads and writes data in a database, and makes sure there is consistency and availability. The supplier table's CREATE TABLE statement(s) must specify a FOREIGN KEY.
The database system often guards data when a lot of transactions is taking place. it often hinders multiple transactions with the same data at the same time.The Select SQL statement does not alter any database data. A supplier database is made up of different list of service, product or materials providers who can meet orders quickly.

A digital computer has a memory unit with 16 bits per word. The instruction set consists of 72 different operations. All instructions have an operation code part(opcode) and an address part(allowing for only one address). Each instruction is stored in one word of memory.
Required:
a. How many bits are needed for the opcode?
b. How many bits are left for the address part of the instruction?
c. What is the maximum allowable size for memory?
d. What is the largest unsigned binary number that can be accommodated in one word of memory?
Answer:
a. 7 bits b. 9 bits c. 1 kB d. 2¹⁶ - 1
Explanation:
a. How many bits are needed for the opcode?
Since there are 72 different operations, we require the number of bits that would contain 72 different operations. So, 2ⁿ ≥ 72
72 = 64 + 8 = 2⁶ + 8
Since n must be an integer value, the closest value of n that would contain 72 different operations is n = 7. So, 2⁷ = 128
So, we require 7 bits for the opcode.
b. How many bits are left for the address part of the instruction?
bits left = bits per word - opcode bit = 16 - 7 = 9 bits
c. What is the maximum allowable size for memory?
Since there are going to be 2⁹ bits to addresses each word and 16 bits for each word, the maximum allowable size for memory is thus 2⁹ × 16 = 512 × 16 = 8192 bits.
We convert this to bytes
8192 bits × 1 byte/8 bits = 1024 bytes = 1 kB
d. What is the largest unsigned binary number that can be accommodated in one word of memory?
Since the number go from 0 to 2¹⁶, the largest unsigned binary number that can be accommodated in one word of memory is thus
2¹⁶ - 1

Your disaster recovery plan calls for tape backups stored at a different location. The location is a safe deposit box at the local bank. Because of this, the disaster recovery plan specifies that you choose a method that uses the fewest tapes, but also allows you to quickly back up and restore files. Which backup strategy would best meet the disaster recovery plan for tape backups?
Store Physical Backup Media Offsite. Like data stored in the cloud, offline data stored on physical media is susceptible to unauthorized access. Offsite media storage helps significantly reduce the possibility of theft and physical damage to your media assets from fires, floods and natural disasters.
An incremental backup is one in which successive copies of the data contain only the portion that has changed since the preceding backup copy was made. ... Incremental backups are often desirable as they reduce storage space usage, and are quicker to perform than differential backups.
