Break/Continue+ 标签 的用法

Break+ 标签 ； 跳出标签所标注的那个语句 , 然后去执行后续语句 .

Continue+ 标签 ； 停止 continue 语句的后续语句的执行 , 跳到标签所标注的语句去执行下一循环 .

public class TestWhile {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        System.out.println("program is begin.");
        int i = 1;
        labelbreak: while (true) {

            while (true) {
                System.out.println("inner: i=" + i);
                if (i == 1) {
                    break;
                }
                if (i % 2 == 0 || i > 2) {
                    break labelbreak;
                }
                i++;
            }
            i++;
            if (i == 10) {
                break;
            }
            System.out.println("outer: i=" + i);

        }
        System.out.println("program is end.");

    }

}
