thread ends due to an exception, a new thread will replace it. This thread pool ensures that all tasks are executed in the order they are submitted.
Test Case:
We create a Text thread for testing:
class Text implements Runnable{ String name; public Text(String name){ this.name = name; } @Override public void run() { System.out.println(Thread.currentThread().getName() + "--" + name); } }
Now let's test the effect of the threa
