Run BlueJ and create a new BlueJ project in your lab11 folder. Create a new class named JavaAPILabMain in your BlueJ project. Delete the example code and start afresh with a new class definition that contains a main method. To confirm everything is ready to go, add a System.out.println call to your main method and have it print out the name of your favorite movie. Then compile and run the program to verify that it works.

Part 1: Explore the Java API

Using the two left-hand frames in the API browser-window, find the String class and display its details in the large frame.

Notice that right above the words Class String are the words java.lang in a smaller font. java.lang is the package in which class String may be found. You already know that often you need to add an import statement to your program to make certain classes available; this is how you find out whether you need an import statement and, if so, which one. As it happens, java.lang is Javas default package: you never need to add an import statement for java.lang, because these classes are always available. If a different package name should appear there, however, you will know that you need to add an import statement to your program if you wish to use that class. You will need to use this fact later in this lab.

Answer the questions below:

1.Jill has two strings s1 and s2 which each contain different email addresses (e.g., ). She wants to know if both addresses are from academic institutions. The easiest way to do this is to see if both addresses end with . Find the best method in the String class for doing this and complete the code Jill should use below:

boolean bothEduAddresses = _________________________________;

2.Paul is writing software to store information about all the card carrying members of his secret club. Each membership card is stamped with a unique ID that contains three sections separated by hyphens. These sections are always four digits, four characters and then eight digits respectively. For example, one ID is 1994-NEPR-48573923.

Find the best method in the String class for comparing two ID strings to see if their second sections match. No other methods in the String class should be necessary. Write a code snippet using that method to compare the 4^th and 14^th entry in the members array to see if their second sections match.
