* Java, make 2 exception classes that will throw errors, the class notgreaterthan10exception is provided in the picture. Create the 2 classes lessthanorequaltoexception and lessthanexception

sample output of what it should do is provided.

tell me if somwthing else is needed

Instructions This program will allow us to enter data for the shapes that we have created in the previous labs. Specifically we want to enter the width, length, and height values. The width and length must be integers (whole numbers) greater than 0. Height may be 0. otherwise it must be a positive integer. Make sure that you are familiar with the example program CreateAndUseException Example from the Chapter 11 lecture notes. You may find it helpful to enter compile, and run this program. Do not forget to enter and compile the class Integer NotGreater Than 10Exception. Of course, both classes must be compiled in the same folder. To accomplish this task you will need to: 1. Create 2 exception classes that will throw errors (see the lecture notes class IntegerNotGreater Than10Exception) a. Less Than OrEqualToZeroException b. Less ThanZeroException 2. Write an executable class called InputWidthLength Height which asks the user to inputs value for three variables of type integer: height, length, width. a. Print your name, Lab number, and date as the first three lines of output. Hard-code the date...do not use the system date You will want to create two public static void methods in this class that will test the data and throw the correct exception. i. public static void less ThanOrEqualToZeroException(String myField, int myNumber throws LessThanOrEqualToZeroException public static void lessThanZeroException( String myField, int myNumber ) throws Less Than ZeroException myField is the current field that is attempting to be input, i.e. " width", "length", "height": iv. myNumber is the value that the user has input c. Input data If the user's data causes an exception your program should respond by explaining the error and asking the user to reenter the inappropriate value. Handle any exceptions which might occur. Your program should not "blow up" or crash but continue to run until all three values contain an appropriate value. iii. Do not use generic exception handling. Set up a catch block for each specific exception you encounter 1. height must be greater than or equal to zero: catch Less Than ZeroException width and length must be greater than 0: catch Less ThanOrEqualToZeroException 3. non-numeric or decimal inputs: catch InputMismatchException All three values must be input with valid data. Once all three value are entered then display a message that alerts the user to the successful input. d. Calculate and display the width to length ratio(width divided by length) 3.
