Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

class CGPA {
       public static void main(String arg[]) {
       int num = 5;

       double mm[] = new double[num];

       double gg[] = new double[num];

        double cgpa, sum = 0;

        mm[0] = 95;

        mm[1] = 85;

        mm[2] = 75;

        mm[3] = 80;

        mm[4] = 95;

            for (int i = 0; i < num; i++) {
            gg[i] = (mm[i] / 10);
            }

            for (int i = 0; i < num; i++) {
            sum += gg[i];
            }

        cgpa = sum / num;

        System.out.println("CGPA = " + cgpa);

        System.out.println("percantage from CGPA = " + cgpa * 9.5);

                                }
}

Result
