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

How many times will the following loop execute? Write the output of the code:
int x=10; while (true){ System.out.println(x++ * 2); if(x%3==0) break; }Define a class to accept a number from user and check if it is an EvenPal number or not.
(The number is said to be EvenPal number when number is palindrome number (a number is palindrome if it is equal to its reverse) and sum of its digits is an even number.)
Example: 121 – is a palindrome number
Sum of the digits – 1+2+1 = 4 which is an even number
