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

Answer 1

I have used thread to print the output of System.out and System.err sequentially as:

    for(int i = 0; i< 5; i++){
        try {
            Thread.sleep(100);
            System.out.print("OUT");
            Thread.sleep(100);
            System.err.print("ERR");
        }catch (InterruptedException ex){
            System.out.println(ex.getMessage());
        }
    }
