Lab Activities: Exercise 1: 1) Write a thread class TabPrinter that prints the elements of an array of integers (in one line) every 2 seconds 5 times. Use the way of extending the class thread. Write the main method which creates and starts three threads Printer which will print different arrays of integers. After that it prints "Main won't wait. Main exits". 2) Modify the above thread program so that you implement the interface Runnable. Make the main thread waiting till all other threads finish execution.
