java 中 break 只会跳出当前层的循环 不会跳出 上一次的循环

for(int i = 0; i < 10; i++){
            for (int j = 0; j < 10; j++){
                if (j == 5){
                 break;
                }
                System.out.println("i ==" + i);
                System.out.println("j == " + j);
            }
        }

 输出：
i ==0
j == 0
i ==0
j == 1
i ==0
j == 2
i ==0
j == 3
i ==0
j == 4
i ==1
j == 0
i ==1
j == 1
i ==1
j == 2
i ==1
j == 3
i ==1
j == 4
i ==2
j == 0
i ==2
j == 1
i ==2
j == 2
i ==2
j == 3
i ==2
j == 4
i ==3
j == 0
i ==3
j == 1
i ==3
j == 2
i ==3
j == 3
i ==3
j == 4
i ==4
j == 0
i ==4
j == 1
i ==4
j == 2
i ==4
j == 3
i ==4
j == 4
i ==5
j == 0
i ==5
j == 1
i ==5
j == 2
i ==5
j == 3
i ==5
j == 4
i ==6
j == 0
i ==6
j == 1
i ==6
j == 2
i ==6
j == 3
i ==6
j == 4
i ==7
j == 0
i ==7
j == 1
i ==7
j == 2
i ==7
j == 3
i ==7
j == 4
i ==8
j == 0
i ==8
j == 1
i ==8
j == 2
i ==8
j == 3
i ==8
j == 4
i ==9
j == 0
i ==9
j == 1
i ==9
j == 2
i ==9
j == 3
i ==9
j == 4

 从上面可以看到，break 只是跳出当前层的循环
