Write it, run it, read the output

This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Implement the same one-pass candidate scan in Java for the array [4, 1, 1, 3, 2]. A value may replace second only when it is strictly greater than min and smaller than the current second, or when no second candidate exists. Print 2, while retaining the hasSecond branch that prints -1 when no distinct second minimum exists.
