Now I create a test that uses the threads I used in the single-threaded tests to create one with both threads running at the same time.

 public class B''''''othThreadsTogether extends Test{
    public BoundedBuffer buffer;
    public P''''''utThread putThread;
    public T''''''akeThread takeThread;
    
    public void setUp(){
        buffer = new BoundedBuffer();
        putThread = new P''''''utThread(buffer);
        takeThread = new T''''''akeThread(buffer);}
    
    public void runTest (){
        T''''''akeThread.resetOutput();
        putThread.start();
        takeThread.start();
        waitForTakeToFinish();
        should(T''''''akeThread.doesOuputInclude(0, "a"), "first out should be a");
        should(T''''''akeThread.doesOuputInclude(1, "b"), "second out should be b");
        should(T''''''akeThread.doesOuputInclude(2, "c"), "third out should be c");
        should(T''''''akeThread.doesOuputInclude(3, "d"), "fourth out should be d");
        should(T''''''akeThread.doesOuputInclude(4, "e"), "last out should be e");}
        
    public void waitForTakeToFinish(){
        try {
            takeThread.join(1000);}
        catch (InterruptedException exception) {};}
 }

This one runs fine as well.
