Important Note: Please follow the java coding style. Comment your code. Maintain indentation. 10% of this lab assignment is reserved for coding style and documentation. For both of the following problems write your own exception class InvalidInputException that extends the Exception class. The class should have one constructor that does not take any parameter and prints only Invalid input!" and another constructor that takes the invalid input as parameter to show it with the error message. Example: "You provided 3N which is not a valid nput Problem 1: Write a program in java that takes a double value as input from user and prints the square of it. Add appropriate exception handling code block in case the user provides any string other than a double value Sample dialogue: Enter a number: 3.2 The square of the number is: 10.24 Enter a number: 3N The value you provided is invalid Problem 2: Write a program in java that asks user to enter a whole number and keeps asking in case user enters wrong input. Input checking should be done within try/catch block. Sample dialogue: Enter a whole number: forty two Incorrect input. Please try again! Enter a whole number: fortytwo Incorrect input. Please try again! Enter a whole number: 42 You entered: 42
