In Java do the following tasks: Task 1: Define an exception class called MessageTooLongException. The class should have a default constructor. If an exception is thrown using this zero-argument constructor, getMessage should return Message too Long!. This class should also define a constructor having a single parameter of type String. If an exception is thrown using this constructor, getMessage should return the value that was used as an argument to the constructor. Task 2: Write an application called UserInput that asks the user to enter a line of text having no more than 20 characters. If the user enters an acceptable number of characters, the program should display the message You entered x characters, which is an acceptable length (with the letter x replaced the actual number of characters). Otherwise, a MessageTooLongException should be thrown and caught. In either case, the program should repeatedly ask whether the user wants to enter another line or quit the program.
