Write a java application program that takes in user input from keyboard and calculate semester grade based on the scores. I need help, to rewrite the program, instead of taking keyboard input, you will use dialog box to prompt user, take input, and display result.
Pseudo code for the Grading Program
==========
BEGIN
Initialize Score to 0
Initialize Grade to 'F'
Initialize Letter to ‘B'
While the Letter IS NOT 'E' or ‘e'
Input Score
If the Score is greater than or equal to 90
Set Grade to 'A'
else if the Score is greater than or equal to 80
Set Grade to 'B'
else if the Score is greater than or equal to 70
Set Grade to 'C'
else if the Score is greater than or equal to 60
Set Grade to 'D'
else
Set Grade to 'E'
print Grade
print enter 'E' or 'e' to end otherwise enter any other character
Input Letter
END
