public class Main {
public static void main(String[] args) {
int[][] arr = {{11,33,55},{22,44,66,88},{131,214,315,146},{928,827,726,625},{424,525}};
int sum=add(arr);
System.out.println(sum);
}
public static int add(int[][] arr) {
// 压行处理，双重循环，foreach语法
int sum = 0;
for (int[] ints : arr) for (int anInt : ints) sum += anInt;
return sum;
}
}
