Exception Handling

 Exception Handling

1. Create three exception classes named NumberHighException, NumberLowException, and NumberNegativeException. Both NumberHighException and NumberLowException should be directly subclassed from the Exception class, but NumberNegativeException should be subclassed from NumberLowException. You can use the BadDataException class that was defined in this module as the model for your exception classes.

Next create a class called Verify that will be used to validate that a number is within a specified range. It should have one constructor that has 2 int parameters. The 1st parameter is the minimum number in the range, and the 2nd parameter is the maximum number in the range.

In addition to the constructor, the Verify class should have one method that is named validate. The validate method will have a single parameter of data type int. The parameter contains the number that is being validated. If the value of the parameter is less than zero, the method should throw a NumberNegativeException. If the value is less than the minimum value of the range, it should throw a NumberLowException. If the value is greater than the maximum value of the range, it should throw a NumberHighException. If the value is within the specified range, no exception should be thrown.

Once all of these classes are created, create the driver class called Program5. The driver class should instantiate a Verify object with a range of 10 to 100. It should then do the following:

 Prompt the user to input a number within the specified range.  Use a Scanner to read the user input as an int. You can ensure that an int was entered because the nextInt method in the validate class throws an InputMismatchException if any non digits are entered.  Call the validate method to validate that the number is within the range.  Print an appropriate error message if the value is not within the range, or print the value if it is within the range. 2. You may use any Java Integrated Development Environment (IDE) you choose to develop your source code, compile and link your code, and execute your program (jGRASP is recommended). Or you may use the Windows Command Prompt.

You are to submit the following deliverables in a single Microsoft Word file in this order, and clearly labeled.

 A screen snapshot of your Java source code (all file(s) shown separately) displayed in the IDE or Windows editor showing a successful compilation if possible (only the beginning of the source file(s) are necessary).  A listing of your entire source code file(s).  A screen snapshot of all of your program's outputs for the specified values in Step #1. Failure to show any of them will result in lost points. 2. Your instructor may compile and run your program to verify its correctness. 3. You will be evaluated on (in order of importance):  Following directions and inclusion and packaging of all deliverables in Step #2.  Correct execution of your program (this includes proper compilation). This also includes getting the correct answers!  Proper commenting of your Java code and indentation (as specified in the text).  Neatness in packaging of your deliverables (to include putting the items in Step #2 in the correct order).
