Java Program**

Write a program for the following problem. You are given a collection of scores for the last exam in your computer course. You are to compute the average of these scores, and then assign grades to each student according to the following rule. If a student's score is within 10 points (above or below) of the average, give the student a grade of SATISFACTORY. If the score is more than 10 points higher than the average, give the student a grade of OUTSTANDING. If the score is more than 10 points below the average, give the student a grade of UNSATISFACTORY. Test your program on the following data:

Hint: The output from your program should consist of a labelled three-column list containing the name, exam score, and grade of each student.

Explanation / Answer

/**The java program that calculates the names,scores and result
* of students on three column table on console.*/
//Testgrades.java
public class Testgrades {
   public static void main(String[] args) {
       //set names of the array
       String names[]={"RICHARD LUGAR",
               "FRANK RIZZO",
               "DONALD SCHAEFFER",
               "KEVIN WHITE",
               "JAMES RIEHLE",
               "ABE BEAME",
               "TOM BRADLEY",
               "WALTER WASHINGTON"
       };

       //set scores as array
       int scores[]=
           {
               55,71,84,93,74,70,84,68
           };

       String result="";

       double totalScore=0;
       //calculate total score
       for (int i = 0; i < scores.length; i++)
           totalScore=totalScore+scores[i];  

       //calculate average
       double avgScore=totalScore/scores.length;

       System.out.println("Average score : "+avgScore);
       for (int i = 0; i < scores.length; i++)
       {
           //check if score in above 10 on average score
           if(scores[i]>avgScore+10)
               result="OUTSTANDING";
           //check if score is within 10 witin points on scores
           else if(scores[i]>avgScore-10 || scores[i]<avgScore+10)
               result="SATISFACTORY";
           else
               result="UNSATISFACTORY";
          
           System.out.printf("%-25s%-10d%-25s ",
                   names[i],
                   scores[i],
                   result);
       }
   }
}

Sample Output :

Average score : 74.875
RICHARD LUGAR 55 SATISFACTORY   
FRANK RIZZO 71 SATISFACTORY   
DONALD SCHAEFFER 84 SATISFACTORY   
KEVIN WHITE 93 OUTSTANDING
JAMES RIEHLE 74 SATISFACTORY   
ABE BEAME 70 SATISFACTORY   
TOM BRADLEY 84 SATISFACTORY   
WALTER WASHINGTON 68 SATISFACTORY
