A database has one physical schema and one conceptual (logical) schema but many external schemas (views).
a) True
b) False
Answer:
true
Explanation:
A database has one physical schema and one conceptual (logical) schema but many external schemas (views): a. True.
A database refers to a structured (organized) collection of data that are stored on a computer system and usually accessed in various ways such as electronically.
In database management, a database schema can be defined as a structure which is typically used to represent the logical design of the database. Thus, it denotes how data are stored (organized) and the relationships existing in a database management system (DBMS).
Generally, there are two (2) main types of a database schema and these include;
Physical database schema: it is only one per database.Conceptual (logical) schema: it is only one per database.However, there are multiple number of external schemas (views) for each database because it is what an end user is interested in.

Write code which takes a sentence as an input from the user and then prints the length of the first word in that sentence.
Hint: think about how you know where the first word ends - you may assume that the sentence contains more than one word.
Input a code in the following:
/* Lesson 3 Coding Activity Question 4 */
import java.util.Scanner;
public class U2_L3_Activity_Four{
public static void main(String[] args){
/* Write your code here */
}
}
import java.util.Scanner;
public class U2_L3_Activity_Four {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.println("Enter a sentence.");
String sent = scan.nextLine();
int count = 0;
for (int i = 0; i < sent.length(); i++){
char c = sent.charAt(i);
if (c != ' '){
count++;
}
else{
break;
}
}
System.out.println("The first word is " + count +" letters long");
}
}
We check to see when the first space occurs in our string and we add one to our count variable for every letter before that. I hope this helps!

g You and your friend both send documents to the printer, but the printer can only print one document at a time. What does it do with the other document
Answer:
It places the document in a buffer
Explanation:
Since the printer can only print a document at a time, the other document is going to be placed in a buffer.
The print buffer can be described as a location in memory that has the function of holding data that is going to be sent to a computers printer. A print job such as in this scenario may remain in the buffer because another document is to be printed first.
Sometimes a document could be put in the buffer because the computer is waiting for the printer to respond. This is just another reason why documents are placed in a buffer.
Write a method called rotate that moves the value at the front of a list of integers to the end of the list. For example, if a variable called list stores the values [8, 23, 19, 7, 45, 98, 102, 4], then the call of list.rotate(); should move the value 8 from the front of the list to the back of the list, changing the list to store [23, 19, 7, 45, 98, 102, 4, 8]. If the method is called for a list of 0 elements or 1 element, it should have no effect on the list. You may neither construct any new nodes to solve this problem nor change any of the data values stored in the nodes. You must solve the problem by rearranging the links of the list.
Answer:
Explanation:
public void rotate()

ListNode current = front;
ListNode firstNode = current;
while(current.next != null)
{

Which input value causes the loop body to execute a 2nd time, thus outputting "In loop" again? { String s = "Go"; while ((!s.equals("q"))&& (!s.equals("")) System.out.println("In loop"); 5 - scnr.nextO;
a) "Quit"
b) "q" only
c) "Q only
d) Either "q" or "Q"
Answer:
a) "Quit"
c) "Q only
Explanation:
Given
String s = "Go";
while ((!s.equals("q"))&& (!s.equals(""))) {
System.out.println("In loop");
s = scnr.next();
}
Required
What input causes another execution
Analyzing the while condition
while ((!s.equals("q"))&& (!s.equals("")))
This can be split into:
!s.equals("q")) && (!s.equals(""))
Meaning
When s is not equal to "q" and when s is not an empty string
In other words,
the loop will be executed when user input is not "q" and user input is not empty.
So, from the list of given options: The loop both will be executed when:
a) Input is "Quit"
c) Input is Q only
Input of q will terminate the loop, hence b and d are incorrect

Write a script that inputs a line of plaintext and a distance value and outputs an encrypted text using a Caesar cipher.
The script should work for any printable characters. An example of the program input and output is shown below:
Enter a message: Hello world!
Enter the distance value: 4
Output: Lipps${svph%
Answer:
def encrypt_text(text,value):
encoded = ""
for i in range(len(text)):
char = text[i]
if (char.isupper()):
encoded += chr"po"ord'po'char'pc' + value -65'pc' % 26 + 65'pc'
else:
encoded += chr'po'ord'po'char'pc' + value -97'pc' % 26 + 97'pc'
return encoded
plaintext = input("Enter sentence of encrypt: ")
dist_value = int(input("Enter number: "))
encrypted = encrypt_text(plaintext, dist_value)
print(encrypted)
Explanation:
The python program above is a Ceasar cipher implementation. The encrypt_text function is defined to accept text input and a distance value, which is used to encrypt the plaintext.
The user can directly input text and the distance value from the prompt and get the encrypted text printed on the screen.

In the Lesson Slides for this activity, we developed a method findChar for figuring out if a character was in a String.
The implementation was:
public boolean findChar(String string, String key)
{
for(int index = 0; index < string.length(); index++)
{
String character = string.substring(index,index+1);
if(character.equals(key))
{
return true;
}
}
return false;
}
However, there is a much more efficient and simple algorithm that we can use to determine if a character is in a String. Using the method signature public boolean findChar(String string, String key), figure out a more efficient method with a lower exection count.
Hint: We’ve learned a couple of methods that can tell us what index a character is at - can we use those to determine if the character is in a String?
public class JavaApplication78 {
public boolean findChar(String string, String key){
if (string.contains(key)){
return true;
}
return false;
}
public static void main(String[] args) {
JavaApplication78 java = new JavaApplication78();
System.out.println(java.findChar("hello", "h"));
}
}
First I created the findChar method using the contains method. It checks to see if a certain sequence of characters is in another string. We returned the result. In our main method, we had to create a new instance of our main class so we could call our findChar method.

a rectangle is 12 cm long and 9 cm wide.Its perimeter is doubled when each of its sides is increased by a fixed length.what is the length?
Answer:
length = 12 cm
breadth = 9 cm.
perimeter of rectangle = 2( l+b)
= 2(12+9) = 2(21) = 42cm.
New length = (12+x) cm
New breath = (9+x) cm
2(12+x+9+x) = 42×2
2(21+x) = 84
21+ x = 84/2
21+x = 42
x= 42-21= 21
x= 21.
Therefore, length = (12+x)cm
=( 12+21) cm = 33cm.
Explanation:
Firstly we have written the length and breadth of the rectangle.
And the perimeter of rectangle i.e. 2(l+b)
Then, as it is in question we have doubled the perimeter
And at last, we have got the value of x.
and by putting the value in the new length we will get our answer.
hope you have got your answer dear.
