Java 二维数组的遍历及应用

二维数组基本使用

 @Test
    public void test1(){
        int[][] accounts = new int[][] {{1,2,3},{1,2,3}};//定义二维数组方法和以为数组相似
        //基本的遍历
        for (int i = 0; i < accounts.length; i++) {
            for (int j = 0; j < accounts[i].length; j++) {
                System.out.println(accounts[i][j]);
            }

        }
    }

算法题：

题解1：

class Solution {
    public int maximumWealth(int[][] accounts) {
        int count = 0;
        for (int i = 0; i < accounts.length; i++) {
            for (int j = 1; j < accounts[i].length; j++) {
                accounts[i][0] += accounts[i][j];
            }
            if(accounts[i][0]>count){
                count = accounts[i][0];
            }
        }
        return count;
    }
}
