I am stuck on the first part. I included my code below. It says my catch is not throwable. The BadDataException class which it says I
can use as a model is a try and catch exception. Would appreciate any help.
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 two int parameters. The first parameter
is the minimum number in the range, and the second 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 should
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
Use a Scanner to read the user input as an int. You can
ensure that an int was entered because the nextInt method 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.
Scanner input = new
an integer >> ");
x = input.nextInt();
x is " + x);

I did one extends class so far
