Question:Explain What The Program Does And Guide The User With Care, Giving Lots Of Instructions And Feedback. Label User Errors

• Explain what the program does and guide the user with care, giving lots of instructions and feedback.
• Label user errors properly and understandably.
• Be sure to format your output nicely so the computing process and the results are understandable.
• need to use the specific exception that code throws

1. Make a program that reads a grade percentage as an integer number from the user in the main method.
2. The program should then send the number to a static method called calculateGrade which will calculate a letter grade from this number and print it out. The header for this method should look like this: public static void calculateGrade(int numIn) {

• Use the table below for the number to grade conversion in your method
• Number to Grade conversion table
• From 0 to 59 grade is F
• From 60 to 69 grade is D
• From 70 to 79 grade is C
• From 80 to 89 grade is B
• From 90 to 100 grade is A

3. The method should print out a nice message telling the user the letter grade.

• Your program must validate the user's input
• You must check it to make sure it is a number and is within the range of allowed percentage values. I suggest you check for a number in the main, and for the range in the calculateGrade method.
• Use try/catch and if/else statements to do this program.
• First check to see that the user has entered a valid integer number.
• If the input is not an integer number, the program should print a message telling the user the error and then exit. It should not call the calculateGrade method!
• Also check that the number is not less than 0 or greater than 100.
• If number is not in that range , the program should print a message telling the user the error and then exit. This can be done as part of the grade calculations in the calculateGrade method.
• The program should not crash at any point no matter what the user enters.
• I will try to crash it and points will be deducted if I can.
• Make sure to test "edge conditions" for correctness:
• If input is 0
• If input is
• if input is 100
• if input is > 100
• if input is 50, 60, 70, 80, or 90
• if input is not a number
• if input has a decimal
