This is my Final Project and as you can see my program asks the users twice for the test grade I am trying to consolodate and have the program only ask for the test score once and give the letter grade at the same time.? any ideas I do not know how to take the input from what is the score for test one and use it with the if else statement. Thank a bunch.
import javax.swing.JOptionPane; //for the JOptionPane class
public class Final
{
// Main method to start program which will find letter grades
// for individual tests and also find average letter grade for all 5 tests
public static void main(String[] args)
{
calcaverage();
}
// Method determineGrade used to determine letter grade for a numeric test score and the average test score
public static void determineGrade()
{
int testScore; //Numeric test score
String input; //To hold user's input
//get the numeric test score.
input = JOptionPane.showInputDialog("Please Re-enter the score to recieve a letter grade.");
testScore = Integer.parseInt(input);
//calculate and display the grade.
if (testScore < 60)
JOptionPane.showMessageDialog(null, "Your Grade is F.");
else if (testScore < 70)
JOptionPane.showMessageDialog(null, "Your Grade is D.");
else if (testScore < 80)
JOptionPane.showMessageDialog(null, "Your Grade is C.");
else if (testScore < 90)
JOptionPane.showMessageDialog(null, "Your Grade is B.");
else if (testScore <= 101)
JOptionPane.showMessageDialog(null, "Your Grade is A.");
else //Invalid score
JOptionPane.showMessageDialog(null, "Invalid score.");
}
