for(int j = 12; j >= 2; j -= 2) {
if(j % 5 == 0)
continue;
System.out.println(j);
}

Answer
Loop executes six times.
Output
12
8
6
4
2
Reason
Step 1: Understanding the Loop
- Initialization:
j = 12 - Condition:
j >= 2(Loop runs whilejis≥ 2) - Update:
j -= 2(Decrementjby 2 each iteration) if (j % 5 == 0) continue;- Skips printing if
jis divisible by5.
Step 2: Iterations Breakdown
| Iteration | Value of j | Condition j % 5 == 0 | Action |
|---|---|---|---|
| 1st | 12 | Not divisible by 5 | Print 12 |
| 2nd | 10 | Divisible by 5 | Skip (continue) |
| 3rd | 8 | Not divisible by 5 | Print 8 |
| 4th | 6 | Not divisible by 5 | Print 6 |
| 5th | 4 | Not divisible by 5 | Print 4 |
| 6th | 2 | Not divisible by 5 | Print 2 |
Step 3: Final Output

To execute a loop 10 times, which of the following is correct?
- for (int i=11;i<=30;i+=2)
- for (int i=11;i<=30;i+=3)
- for (int i=11;i<20;i++)
- for (int i=11;i<=21;i++)
Define a class to accept a four digit number and check whether it is a Framul Number or not. A number is called a Framul Number if the product of all its digits equals fives times the sum of its first and last digit.
Example 1:
Input: 1325
Product of all digits = 1 x 3 x 2 x 5 = 30
Five times sum of first & last digit = 5 x (5 + 1) = 5 x 6 = 30Output: Framul Number
Example 2:
Input: 2981
Product of all digits = 2 x 9 x 8 x 1 = 144
Five times sum of first & last digit = 5 x (1 + 2) = 5 x 3 = 15Output: Not a Framul Number
If the entered number is not of four digits, the message "Please enter a four digit number" should be shown.
import java.util.Scanner; public class KboatFramulNumber { public static void main(String args[]) { Scanner sc = _____(1)_____ System.out.print("Enter a four-digit number: "); int num = _____(2)_____ _______(3)_______ { System.out.println("Please enter a four-digit number"); return; } int d = 0; int f = num % 10; int p = 1; _______(4)_______ { _____(5)_____ _____(6)_____ _____(7)_____ } int s = _____(8)_____ if (p == s) { _______(9)_______ } else { _______(10)_______ } } }Define a class to accept a number and check whether it is a SUPERSPY number or not. A number is called SUPERSPY if the sum of the digits equals the number of the digits.
Example1:
Input: 1021 output: SUPERSPY number [SUM OF THE DIGITS = 1+0+2+1 = 4, NUMBER OF DIGITS = 4 ]Example2:
Input: 125 output: Not an SUPERSPY number [1+2+5 is not equal to 3]Convert the following for loop segment to an exit-controlled loop.
for (int x = 1, y = 2; x < 11; x += 2, y += 2) { System.out.println(x + "\t" + y); }
