Hey to everyone out there. I am new to this forum and seeking assistance with a java program assignment. if anyone can help let me know. The program is completed all I have left is to produce accurate output of a students grade. Here is the code:

////////////////////////////////////////////////////////////////

import javax.swing.JOptionPane;
class Student {
final double ASSIGNMENT_ONE_PERCENTAGE = .10;
final double ASSIGNMENT_TWO_PERCENTAGE = .10;
final double ASSIGNMENT_THREE_PERCENTAGE = .10;
final double ASSIGNMENT_FOUR_PERCENTAGE = .10;
final double MIDTERM_PERCENTAGE = .25;
final double FINALEXAM_PERCENTAGE = .25;
final double PARTICIPATION_PERCENTAGE = .10;

String name, finalLetterGrade;
int assignmentOne = 0;
int assignmentTwo = 0;
int assignmentThree = 0;
int assignmentFour = 0;
int midterm = 0;
int finalExamGrade = 0;
int participation = 0;
double finalNumericGrade = 0;


public Student() {
System.out.println (" Initializing Student...");

}

public void inputGrades() {
name=JOptionPane.showInputDialog("Enter Student's full Name:");
assignmentOne = Integer.parseInt(JOptionPane.showInputDialog( "Enter the Assignment One Grade" ));
assignmentTwo = Integer.parseInt(JOptionPane.showInputDialog( "Enter the Assignment Two Grade" ));
assignmentThree = Integer.parseInt(JOptionPane.showInputDialog( "Enter the Assignment Three Grade" ));
assignmentFour = Integer.parseInt(JOptionPane.showInputDialog( "Enter the Assignment Four Grade" ));
midterm = Integer.parseInt(JOptionPane.showInputDialog( "Enter the Midterm Grade" ));
finalExamGrade = Integer.parseInt(JOptionPane.showInputDialog( "Enter the Final Examination Grade" ));
participation = Integer.parseInt(JOptionPane.showInputDialog( "Enter the Participation Grade" ));
}

public double getAverage(){
finalNumericGrade =
(assignmentOne * ASSIGNMENT_ONE_PERCENTAGE) +
(assignmentTwo * ASSIGNMENT_TWO_PERCENTAGE) +
(assignmentThree * ASSIGNMENT_THREE_PERCENTAGE) +
(assignmentFour * ASSIGNMENT_FOUR_PERCENTAGE) +
(midterm * MIDTERM_PERCENTAGE) +
(finalExamGrade * FINALEXAM_PERCENTAGE) +
(participation * PARTICIPATION_PERCENTAGE);
return finalNumericGrade;
}

private String letterGrade(){
if (finalNumericGrade >= 93)
finalLetterGrade = "A";
else
if ((finalNumericGrade >= 85) & (finalNumericGrade < 93))
finalLetterGrade = "B";
else
if ((finalNumericGrade >= 78) & (finalNumericGrade < 85))
finalLetterGrade = "C";
else
if ((finalNumericGrade >= 70) & (finalNumericGrade < 78))
finalLetterGrade = "D";
else
if (finalNumericGrade < 70)
finalLetterGrade = "F";

return finalLetterGrade;

}


public String toString() {
String studentStringValue= " Student Name is: "+name +"\n";
studentStringValue+= " Assignment One grade is: " + assignmentOne + "\n";
studentStringValue+=" Assignment Two grade is: " + assignmentTwo + "\n";
studentStringValue+=" Assignment Three grade is: " + assignmentThree + "\n";
studentStringValue+=" Assignment Four grade is: " + assignmentFour + "\n";
studentStringValue+=" Midterm grade is: " + midterm + "\n";
studentStringValue+=" Final Exam is: " + finalExamGrade + "\n";
studentStringValue+=" Participation grade is: " + participation + "\n\n";
studentStringValue+=" Final Numeric Grade is: " + finalNumericGrade + "\n";
studentStringValue+=" Final Letter Grade is: " + finalLetterGrade +"\n";

return studentStringValue;
}


public void printName(){
System.out.print(" "+name);
}

}

I can not get the letter grade to reflect in the output. ANy ideas?

I JUST gave you the answer to this problem a couple of days ago. Your program works fine...Nowhere in your code do you actually run the program though..What do you expect it do output if you don't make it output.

This is the link...Don't crosspost. If you have further questions let me know, but your code DOES work fine and will output the grades if you add the output lines like I gave you.
