我写的代码

public class Demo6_6{

public static void main(String[] args){

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

int max = nums[0];

int min = nums[0];

int sum = 0;

double avg = 0;

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

if(nums[i] > max){

max = nums[i];

}

else if(nums[i] < min){

min = nums[i];

}

sum = sum + nums[i];

}

avg = sum /nums.length;

System.out.println("最大值是" + max);

System.out.println("最小值是" + min);

System.out.println("平均值是" + avg);

System.out.println("总和是" + sum);

}

}
