//Mini-exercise: Investigate the substring method for String objects in the Java API. Find out what kind of exception it throws. Create a test class with a main method. Set up a try-catch block that defines a string and finds its length. Once you have the length of your string, modify your program so it creates a substring from your original string, but give it an index that doesn't exist so you get the error message.
