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
