public class {
public static void main(String[] args) {
out:for (int i = 0; i < 3; i++) {
System.out.println("out:" + i);
for (int j = 0; j < 3; j++) {
if(i == 1 && j == 1) {
break out;
}
System.out.println(" in:" + j);
}
}
}
}

输出如下，可以看到(i == 1 && j == 1)条件满足后，内外层循环都停止了

继续外层循环

public class {

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

结果如下，可以看到(i == 1 && j == 1)条件满足后，该次的内层循环停止了，回到外层循环继续

停止多层循环
同理可以跳出或者继续多层的循环，只要在要跳出或继续的循环出设置标识即可

继续多层循环类似，就不贴代码了
