Java Return Result From Thread. The Runnable interface has been around since the beginning of time for the Java platform. This method blocks the current thread to wait until the computation completes and returns the value.
Suppose that you have a class hierarchy in which ImaginaryNumber is a subclass of javalangNumber which is in turn a subclass of Object as illustrated in the following figure. Public class MyTask implements Callable Override public String call throws Exception Here your implementation return new StringResult. First well return arrays and collections.
You can use wait and notify notifyAll with his solution too.
