紅包的分發(fā)見(jiàn)JAVA作業(yè)——紅包分發(fā)。而搶紅包要解決的是線程問(wèn)題。其實(shí)比較簡(jiǎn)單，設(shè)定好人數(shù)，每個(gè)人一個(gè)線程，每個(gè)線程執(zhí)行一遍，有紅包就搶?zhuān)瑳](méi)有紅包就搶不到，所以run函數(shù)中只要判斷現(xiàn)在還有沒(méi)有紅包就可以了。

import java.util.Random;import java.util.Scanner;public class Main { public static void main(String[] args) { int person_num, red_pocket_num, sum_money; Scanner scanner = new Scanner(System.in); System.out.println('請(qǐng)?jiān)O(shè)置紅包個(gè)數(shù):'); red_pocket_num = scanner.nextInt(); System.out.println('請(qǐng)?jiān)O(shè)置總金額數(shù)量(分):'); sum_money = scanner.nextInt(); if(sum_money < red_pocket_num) { System.out.println('錢(qián)不夠，退出程序。'); return; } System.out.println('請(qǐng)?jiān)O(shè)置搶紅包成員個(gè)數(shù):'); person_num = scanner.nextInt(); myRunnable myrunnable = new myRunnable(sum_money,red_pocket_num); Thread []person = new Thread[person_num]; for (int i = 0; i < person_num; i++) { person[i] = new Thread(myrunnable); person[i].setName('用戶'+(i+1)); person[i].start(); } }}class myRunnable implements Runnable{ private int []red_pocket; private int num; private int now_num; public myRunnable(int money, int num) { this.red_pocket = new Red_Pocket(money, num).get_red_packets(); this.num = num; this.now_num = num; } @Override public void run() { if(this.num>0){ System.out.println(Thread.currentThread().getName()+'搶到了紅包 '+(this.num-this.now_num+1)+' : '+red_pocket[--this.now_num]+'分'); } else{ System.out.println(Thread.currentThread().getName()+'未搶到紅包。'); } }}class Red_Pocket{ private long seed; private int money; private int num; public int[] get_red_packets() { if(this.money < this.num) return new int[0]; Random random = new Random(this.seed); this.seed = random.nextLong(); int[] res = new int[this.num]; double[] temp = new double[this.num]; double sum = 0; int sum2 = 0; for (int i = 0; i < this.num; i++) { temp[i] = random.nextDouble(); sum += temp[i]; } for (int i = 0; i < this.num; i++) { res[i] = 1 + (int)(temp[i] / sum * (this.money - this.num)); sum2 += res[i]; } res[random.nextInt(this.num)] += this.money - sum2; return res; } private void init() { this.seed = new Random(System.currentTimeMillis()).nextLong(); } public Red_Pocket(int money,int num) { init(); this.money = money; this.num = num; }}
