想问一下3 5题怎么编
孩子人傻了
编不对

挺好做的，加油(ง •̀_•́)ง

public static void main(String[] args) {
int [] arr = {6,7,8,9,10,11,12,13,14,15};
int max = arr[0];
int min = arr[0];
int sum = 0;
double avg =0;
for (int i = 0; i < arr.length; i++) {
if (arr[i]>max){
max=arr[i];
}
if (arr[i]<max){
max=arr[i];
}
sum = sum+arr[i];
avg = avg+arr[i];
}
avg=avg/arr.length;
System.out.println(max);
System.out.println(min);
System.out.println(sum);
System.out.println(avg);
}

public static void main(String[] args) {
int a [] [] = {{1},{4,5,6},{7,8}};
for (int i = 0; i < a.length; i++) {
for (int j = 0; j < a[i].length; j++) {
System.out.println(a[i][j]);
}
}
}
