How many times will the following loop execute? Write the output of the code:
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
12

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]How many times will the following loop execute? Write the output of the code:
