java array 성적입력받아 성적표 출력하기

import java.util.Scanner;
public class Sungjuk {
public static void  main(String[] args){
Scanner sc = new Scanner(System.in);
System.out.print("이름 입력=>");
String name = sc.next();//문자열입력
System.out.print("HTML 점수=>");
double html=sc.nextDouble();

System.out.print("JSP 점수=>");
double jsp=sc.nextDouble();

System.out.print("JAVA 점수=>");
double java=sc.nextDouble();

double total=html+jsp+java;
double avg=total/3.0;
System.out.println(name+"학생의 점수");

System.out.println("HTML : "+html);
System.out.println("JSP : "+jsp);
System.out.println("JAVA : "+java);

System.out.println("합계 : "+total);
System.out.printf("평균 : %.2f\n" , avg);
System.out.println("-------------------------------");
double[] arr = new double[3];
arr[0]=html;
arr[1]=jsp;
arr[2]=java;
double max;
double min;
        int i;
        max = min = arr[0];
        for(i=1;i<arr.length;i++){
        if(max<arr[i]){
        max= arr[i];
        }
        if(min>arr[i]){
        min = arr[i];
        }
        }
        System.out.println("최대값 : " + max);
        System.out.println("최소값 : " + min);
}
}

                               결과

                               3과목 double로 입력받아서 합계와 평균을 구해서

                               출력해준다.
