Add a statement to Method3 that throws a TestException without a message. (You'll also need to delete or comment out the last statement in Method3 or the compiler will flag it as unreachable.) Add the code necessary to catch this exception in Method2. The catch block should simply display a message at the console. Compile and run the program and observe its operation.

Modify your solution so that a custom message is passed to the TestException and is then displayed in the catch block. Compile and run the program to be sure that the custom message is displayed.

Add another constructor to the TestException class that accepts a Throwable object as a parameter.

Add a try statement to Method3 of the CustomTesterApp class. The try clause should throw an IOException, and the catch clause should throw a TestException, passing the IOException to its constructor.

Modify the catch block in Method2 that catches the TestException so that it displays the original cause of the exception. Compile and run the application to make sure it works.
