Disable System.err

Question

Is there a way to set the stream System.err so everything written to it is ignored? (i.e. discarded not outputted)

Answer 1

Just set Error to dommy implementation:

System.setErr(new PrintStream(new OutputStream() {
            @Override
            public void write(int arg0) throws IOException {
                // keep empty
            }
        }));

You need to have special permission to do that.

RuntimePermission("setIO")
