[Java知识库]Java中增强for循环 for(int x:number) continue中的label: 标签 continue标签

package com.milkyFog.JavaSE;

public class forLoop {
    public static void main(String[] args) {
        //增强for循环
        int[] numbers = {1, 2, 3, 4, 5, 6};
        for (int x : numbers) {
            System.out.println(x);
        }

        //等价于
        for (int i = 0; i < numbers.length; i++) {
            System.out.println(numbers[i]);

        }
        //label:标签
        outer://标记continue从哪里出来，有点goto的意思
        for (int i = 0; i < 100; i++) {
            for (int j = 2; j <= i / 2; j++) {
                if (i % j == 0) {
                    continue outer;
                }

            }
            System.out.print(i + " ");
        }


    }
}
