java代码数组求平均值，最大值，最小值

（测试类）

package com.badu;

public class Tste {

    public static void main(String[] args) {
        Class5 sa=new Class5("周阿郎",3,2,24);
        Class5 [] a=new Class5[5];
        a[0]=new Class5("张扬",2,4,34);
         a [1]=new Class5("刘禅",3,2,24);
        a[2]=new Class5("张燕",4,23,78);
        a [3]=new Class5("周少博",32,23,99);
        a [4]=new Class5("张旭",24,13,100);
        System.out.println(sa.toString());
        double [] w={a[0].getSJava(),a[1].getSJava(),a[2].getSJava(),a[3].getSJava(),a[4].getSJava()};
        int s=0;
            double max=w[2];
            double min=w[0]; 

        for(int i=0;i<5;i++){
            s+=w[i]/5;
            if(max<w[0]){
                max=w[2];
            }
            if(min>w[0]){
                min=w[0]; 

            } 

        }
        System.out.println("java成绩的平均值为"+s+",最小值为"+min+",最大值为"+max);
    }

}

package com.badu;

public class Class5 {
  private String name;
  private int age;
  private int sno;
  private int sJava;
  public  Class5(String a,int w,int g,int l){ 

      name=a;

      sno=g;
      sJava=l; 

  }public  Class5(int b){
      age=b;
  }public Class5(int c,int d){ 

      sno=c;

  }
  public Class5(){}
    public String getName(){

    }
    public int getSJava(){

    }
    public String toString (){
        String s="我叫"+name+",我今年"+age+"岁"+"我的java成绩是"+sJava;
        return s;
    }
    public static void main(String[] args) { 

    }
