Java怀旧：break <label> & continue <label>，break <label>相当于简易的goto了，凑活用了

package com.super119;

public class BreakContinueLabel {

    public static void main(String[] args) {
        bfinish: {
            for (int i = 0; i < 10; i++) {
                System.out.println(i);
                if ( i == 5) break bfinish;
            }
        }
        System.out.println("Break label finished.");
        
        /*
         * This is wrong:
         * cfinish: {
         *     for (int i = 0; i < 10; i++) {

         *     }
         * }
         *
