System.out.println and System.err.println out of order

Question

My System.out.println() and System.err.println() calls aren\'t being printed to the console in the order I make them.

public static         


        

Answer 1

This is a bug in Eclipse. It seems that Eclipse uses separate threads to read the content of out and err streams without any synchronization.

If you compile the class and execute it in the console (with the classic java

), the order is as expected.
