How do you "call output.java program"? Invoking its main()? Process exec? Can you modify output.java to use an arbitrary PrintStream or is it hardcoded to System.out? Give us more details. — polygenelubricants

That's because you're doing it all wrong. The textarea is in a different process so you need to capture the output of the other program yourself.

Try passing a reference of the JTextarea in question to the output.java as a Constructor or method argument.
