CODE:

import java.util.Scanner;

public class Main
{
public static void main(String[] args) {
int g1, g2, g3, g4;
float avg;

Scanner scan=new Scanner(System.in);
System.out.println("Enter grade of Exam 1");
g1=scan.nextInt();

System.out.println("Enter grade of Exam 2");
g2=scan.nextInt();

System.out.println("Enter grade of Exam 3");
g3=scan.nextInt();

System.out.println("Enter grade of Exam 4");
g4=scan.nextInt();

avg= (g1+g2+g3+g4)/4;
System.out.println("Average is: "+avg);
}
}
