为啥我这个数组输出最大值和总数不对

public class imooc_shuzhu2 {

    

    public static void main(String[] args) {

    int[] shuzhu = new int[] { 61, 23, 4, 74, 13, 148, 20 };

      int max=shuzhu[0];

      int min=shuzhu[0];

      double sum=0;

      double avg=0;

      for(int i=0;i<shuzhu.length;i++){

     if(shuzhu[i]>max)

     sum=shuzhu[i];      

     if(shuzhu[i]<min)

     min=shuzhu[i];    

     sum+=shuzhu[i];

      }

 avg=sum/shuzhu.length;

System.out.println("最小值"+min);

System.out.println("最大值"+max);

System.out.println("平均数"+avg);

    }

}

    sum=shuzhu[i];改成max=shuzhu[i];
