a Java program that reads in the following values from the standard input device (i.e. Keyboard) an

Provided that it is ultimately the responsibility of the students to 
comprehensively test their program and make sure that it indeed 
satisfies all explicit and implicit requirements for a given project; 
the following few test cases are just ment to give you some ideas on 
how to go about testing your first project (projA):

	Test Case: 1 (valid inputs)
	Aim: To test if the number of months is zero the result is correct.
	Inputs:
		A (loan Amount)= 100000.00
		r (interest rate)= 10
		Y (number of years)= 10
		M (number of months)= 0

	Output:	
		R (monthly Repayents): $1356.21

        Test Case: 2 (valid inputs)
        Aim: To test if the number of months is not zero the result is correct.
        Inputs:
                A (loan Amount)= 100000.00
                r (interest rate)= 10
                Y (number of years)= 9
                M (number of months)= 12

        Output:
                R (monthly Repayents): $1356.21


        Test Case: 3 (valid inputs)
        Aim: To test if the number of years is zero and the number of months
	     is correct (i.e. <= 12) the result is correct.
        Inputs:
                A (loan Amount)= 100000.00
                r (interest rate)= 10
                Y (number of years)= 0
                M (number of months)= 12

        Output: 
                R (monthly Repayents): $9166.67


        Test Case: 4 (invalid inputs)
        Aim: To test that an invalud amount is not accepted.
        Inputs:
                A (loan Amount)= -100000.00
                r (interest rate)= 10
                Y (number of years)= 9
                M (number of months)= 12

        Output:
		Some error message for the invalid amount!


        Test Case: 5 (invalid inputs)
        Aim: To test that an invalud interest rate is not accepted.
        Inputs:
                A (loan Amount)= 100000.00
                r (interest rate)= -10
                Y (number of years)= 9
                M (number of months)= 12

        Output:
                Some error message for the invalid interest rate!


        Test Case: 6 (invalid inputs)
        Aim: To test that an invalud value for year(s) is not accepted.
        Inputs:
                A (loan Amount)= 100000.00
                r (interest rate)= 10
                Y (number of years)= -9
                M (number of months)= 12

        Output:
                Some error message for the invalid year(s)!


        Test Case: 7 (invalid inputs)
        Aim: To test that an invalud value for months is not accepted.
        Inputs:
                A (loan Amount)= 100000.00
                r (interest rate)= 10
                Y (number of years)= 9
                M (number of months)= -12

        Output:
                Some error message for the invalid months!
