break的标签的用法

package study;

public class breakdemo {
	public static void main(String[] args) {
		System.out.println("1");
		System.out.println("2");
		System.out.println("3");
		System.out.println("4");
		System.out.println("5");
		System.out.println("6");
		System.out.println("7");
m1://标签，用于break跳出循环只能放在for前面或者后面，中间不能放语句
		for (int i = 0; i < 5; i++) {
			System.out.println("for"+i);
			if (i==3) {
				break m1;
			}
		}

	}
}
