Test Four Threads Running

Now lets try four threads together:

 public class FourThreadsTogether extends Test {
    public BoundedBuffer buffer;
    public PutThread firstPutThread;
    public PutThread secondPutThread;
    public TakeThread firstTakeThread;
    public TakeThread secondTakeThread;

    public void setUp(){
        buffer = new BoundedBuffer();
        firstPutThread = new PutThread(buffer);
        secondPutThread = new PutThread(buffer);
        firstTakeThread = new TakeThread(buffer);
        secondTakeThread = new TakeThread(buffer);}

    public void runTest (){
        TakeThread.resetOutput();
        firstTakeThread.start();
        secondTakeThread.start();
        firstPutThread.start();
        secondPutThread.start();
        waitForTakeToFinish();
        should(TakeThread.doesOuputHaveTwoOf("a"), "should get two a");
        should(TakeThread.doesOuputHaveTwoOf("b"), "should get two b");
        should(TakeThread.doesOuputHaveTwoOf("c"), "should get two c");
        should(TakeThread.doesOuputHaveTwoOf("d"), "should get two d");
        should(TakeThread.doesOuputHaveTwoOf("e"), "should get two e");}

    public void waitForTakeToFinish(){
        try {
            firstTakeThread.join(1000);
            secondTakeThread.join(1000);}
        catch (InterruptedException exception) {};}
 }

I was expecting problems of some sort with this one, but it runs just fine.
