Answer 2

import java.util.*;
public class Main {

public static void main(String[] args) {
Scanner read = new Scanner(System.in);
double score1 = read.nextDouble();
double score2 = read.nextDouble();
double score3 = read.nextDouble();
double score4 = read.nextDouble();
double avgScore = getAverageScore(score1, score2, score3, score4);
System.out.println(avgScore);
}
//create your method here
public static double getAverageScore(double a,double b,double c,double d) {

double dd = a+b+c+d ;
dd=dd/4;
return dd;

}
}

How to use the concept here?

public class Main {

public static void main(String[] args) {
Scanner read = new Scanner(System.in);
double score1 = read.nextDouble();
double score2 = read.nextDouble();
double score3 = read.nextDouble();
double score4 = read.nextDouble();
double avgScore = getAverageScore(score1, score2, score3, score4);
System.out.println(avgScore);
}
//create your method here
public static double getAverageScore() {

}
}
