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

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
