Question # 2                                                                                                                              Marks 10     

You will write a simple Java code that will demonstrate working of threads. You will write two classes, one CS508.java and 2^nd one will be SimpleThread.java.

SimpleThead.java will extend the thread class. In run method, your thread will display its name and number of milliseconds (0 to 5000) it will sleep for. And then it will sleep randomly for 1 to 5000 milliseconds. Once thread has finished it will display its name and message that it has finished. One thread will sleep 5 times before ending.

In CS508.java, you will create 3 threads of SimpleThread  and will run them. Name of the first thread will be your name, name of second thread will be your VU student id, and name of 3^rd thread will be VU.

Here is the sample output of the code that you will write

Note:

1) No need to send the java/class files, put code in word file along with answer of the first question.

2) For question number one you can search over the internet. But do not copy paste the contents as it is , use your own words.
