audio - Java generating sound

Question

I created a pong clone and I would like to add some sound effects when collisions occur. My problem is that every example I could find about synthesizing sound takes about 30 lines of code, considering my whole application has only 90 lines of code. I am looking for a simpler approach. Is there a simple way to create a beep sound of different tones? Duration does not matter. I just want a series of beeps with different tones.

Here's a small example taken (and shortened) from Java Sound - Example: Code to generate audio tone

    byte[] buf = new byte[ 1 ];;
    AudioFormat af = new AudioFormat( (float )44100, 8, 1, true, false );
    SourceDataLine sdl = AudioSystem.getSourceDataLine( af );
    sdl.open();
    sdl.start();
    for( int i = 0; i < 1000 * (float )44100 / 1000; i++ ) {
        double angle = i / ( (float )44100 / 440 ) * 2.0 * Math.PI;
        buf[ 0 ] = (byte )( Math.sin( angle ) * 100 );
        sdl.write( buf, 0, 1 );
    }
    sdl.drain();
    sdl.stop();
