java中break与continue

break:

for (int i = 0; i < 3; i++) {

    for (int j = 0; j < 3; j++) {
        if (j == 1) {
            break;
        }
        System.out.println("i,j:" + i + "," + j);
    }

}

输出：

i,j:0,0
i,j:1,0
i,j:2,0

continue:

for (int i = 0; i < 3; i++) {

    for (int j = 0; j < 3; j++) {
        if (j == 1) {
            continue;
        }
        System.out.println("i,j:" + i + "," + j);
    }

}

输出：

i,j:0,0
i,j:0,2
i,j:1,0
i,j:1,2
i,j:2,0
i,j:2,2

结论: break 放在子循环，会跳出内层循环体

        continue 只会结束本次 内层循环

跳出外层循环，添加标签：

outer:

for (int i = 0; i < 3; i++) {

    for (int j = 0; j < 3; j++) {

        if (j == 1) {
            break outer;
        }

        System.out.println("i,j:" + i + "," + j);

    }

}

输出：

i,j:0,0
