Question

Write a program that calculates the total grade for three classroom exercises as a percentage. Use the DecimalFormat class to output the values as a percent. The scores should be summarized in a table. Accept the assignment information in this order:

Name of assignment (may include spaces)

Points earned (integer)

Points possible (integer)

Output should look similar to the following (bold italics indicates input)

Name of Assignment: Group Project Points

Points Earned: 10

Points Possible: 10

Name of Assignment: Homework

Points Earned: 7

Points Possible: 12

Name of Assignment: Presentation

Points Earned: 5

Points Possible: 8

Assignment Pts Earned Pts Possible

Group Project 10 10

Homework 7 12

Presentation 5 8

Total 22 30

Score 73.3%

       int[] Points earned = new int[3];
       int[] Points possible = new int[3];      
       int Total = 0, totalPoints possible = 0;
      
       for(int i = 0; i < 3; i++)
       {
           System.out.println("Name of exercise " + (i + 1) + ":");
           Name of assignment[i] = input.nextLine();
          
           System.out.println("points earned " + (i + 1) + ":");
           Points earned[i] = input.nextInt();
           Total += Points earned[i];
          
           System.out.println("points possible " + (i + 1) + ":");
           Points possible[i] = input.nextInt();
           totalPoints possible += Points possible[i];
          
           input.nextLine();          
       }
      
       input.close();
       DecimalFormat myFormat = new DecimalFormat("#.00%");
      
       //formatting output      
       System.out.printf("%n%-20s %-10s %-10s%n", "Assignment", "pts earned", "pts Possible");
       System.out.printf("%-20s %-10d %-10d%n", Name of assignment[0], Points earned[0], Points possible[0]);
       System.out.printf("%-20s %-10d %-10d%n", Name of assignment[1], Points earned[1], Points possible[1]);
       System.out.printf("%-20s %-10d %-10d%n", Name of assignment[2], Points earned[2], Points possible[2]);
       System.out.printf("%-20s %-10d %-10d%n", "Total", Total, totalPoints possible);
      
       System.out.print(" Your total is " + Total + " out of " + totalPoints possible);
       System.out.println(", or " + myFormat.format((double)Total / totalPoints possible) + ".");
