Java Question

Learning Goal: I’m working on a java question and need an explanation and answer to help me learn.

For this programming assignment, you will re-implement the java program that you

implemented in the fourth programming assignment for storing grades of students, finding

the average of grades, the maximum and minimum grade, and printing the name and grade

of a student given their ID number.

Program Input Handling

This phase of the program is the same as the previous programming assignment, except

this time, you need to do error handling as well. The program first asks the user to enter

the information of the first student via keyboard by printing the following message: After

Welcome to my grade book version 2!

Please enter the information of the first student using the following format:

“firstName lastName PID grade”.

Press Enter when you are done.

user enters the requested information (e.g. “Ann Smith 1234567 93”), the program must

repetitively ask for information of the next student by printing the following message in a

while loop:

Please enter the information of the next student using the same format.

If there is no more students, please enter the keyword “DONE”.

Press Enter when you are done.

The program must ask the user to try again (re-enter a student’s information) if the

input does not meet any of the following criteria:

firstName is a single word and does not include any white space character.

lastName is a single word and does not include any white space character.

PID is a seven digit integer with no leading zeros.

grade is a non-negative integer that doesn’t exceed 100.
