コンソール出力を GUI の TextArea にリダイレクトするにはどうすればよいですか?

<code class="java">public class GUIOutputRedirection {

    private TextArea textArea;
    private PrintStream originalPrintStream;

    public GUIOutputRedirection(TextArea textArea) {
        this.textArea = textArea;
        originalPrintStream = System.out;
    }

    public void redirectOutput() {
        PrintStream stream = new PrintStream(new OutputStream() {

            @Override
            public void write(byte[] b, int off, int len) {
                String text = new String(b, off, len);
                textArea.append(text);
                originalPrintStream.write(b, off, len);
            }

            @Override
            public void write(byte[] b) {
                write(b, 0, b.length);
            }

            @Override
            public void write(int b) {
                byte[] b1 = new byte[1];
                b1[0] = (byte) b;
                write(b1, 0, 1);
            }
        });

        System.setOut(stream);
    }

    // ...
}</code>

<code class="java">GUIOutputRedirection redirection = new GUIOutputRedirection(textArea);
redirection.redirectOutput();</code>
