Given: public class TestLoop1 { public static void main(String[] args) { int a = 0, z=10; while (a < z) { a++; --z; } System.out.print(a + " : " + z); } } What is the result?

The loop starts with `a=0` and `z=10`. In each iteration, `a` increments by 1 and `z` decrements by 1. The loop continues as long as `a < z`. They will meet when `a` reaches 5 and `z` reaches 5, at which point the condition `a < z` (5 < 5) becomes false, and the loop terminates, printing their final values.

This result would imply the loop executed one more time than it should have or the values were miscalculated, as `a` and `z` would not simultaneously be 6 and 4 at termination.

This output implies an incorrect number of loop iterations or miscalculation of `a` or `z`'s final value.

This result suggests an off-by-one error in tracking `a` or `z` during the loop execution, inconsistent with the symmetric increment/decrement until `a < z` is false.
