Java Code Analysis: Predicting Output of a While Loop

Predict the output of the following code:

int m = 4;
int n = 15;
while(m++ < -n){
System.out.println(m++ + n);
}

Options:

A) 99 B) 89

C) 10 10 D) 10 9

Correct Answer: D) 10 9

Explanation:

The while loop will not execute as the condition m++ < -n is false. The value of m remains 4 and n remains 15. Therefore, nothing will be printed.

Reasoning:

1. Loop Condition: The condition m++ < -n evaluates to 4 < -15, which is false. This is because m++ increments m after the comparison, so m remains 4.
2. Loop Execution: As the condition is false, the loop will not execute.
3. No Output: Since the loop body is not executed, no output will be printed.

Conclusion:

The provided Java code will not produce any output because the while loop's condition evaluates to false and the loop does not execute.
