Question

Java Newbie question :

I need to capture the text being written to a printStream by a 3rd party component.

The PrintStream is defaulted to System.err, but can be changed to another PrintStream.

Looking through the docs, I couldn’t find an easy way to direct the contents of a PrintStream to a string writer / buffer.

Can someone please assist?

PipedOutputStream pipeOut = new PipedOutputStream(); PipedInputStream pipeIn = new PipedInputStream(pipeOut); System.setOut(new PrintStream(pipeOut)); // now read from pipeIn
