java 黄金点游戏

  最近自己使用纯java写的黄金点游戏,写的不是很好,希望各位多多指点。本来想使用swing来做几个按钮的,但是对这个确实不是很懂,还是放弃了,采用了控制台输入的方式。主要是

使用hashmap来存储参加游戏的name和每次输入的数据。

代码如下:

package demo2;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Scanner;

public class GoldPoint {
public static void main(String[] args){
	GoldPoint gd=new GoldPoint();
	gd.goldPoint();
}
public void goldPoint(){
	HashMap<String,Double> inputMap=new HashMap<String,Double>();//存入输入分数
	HashMap<String,Double> scoreMap=new HashMap<String,Double>();//存入分数
	String name="";
	Double inputScore;
	int peopleNum;//参加的人数
	int time;//进行轮数
	Double sum=0.0;
	Double aver=0.0;
	Scanner scan=new Scanner(System.in); //参数对象是系统进来的流
	System.out.println("输入参加的人数:");
	peopleNum=scan.nextInt();
	System.out.println("输入需要进行几轮:");
	time=scan.nextInt();
	for(int i=0;i<peopleNum;i++){
		System.out.println("请输入第"+(i+1)+"个参加者的姓名:");
		name=scan.next();
		System.out.println("请输入第一轮的分数:");
		inputScore=scan.nextDouble();
		 inputMap.put(name, inputScore);
		 scoreMap.put(name,(double) 0);//初始化scoreMap
		 sum+=inputScore;
	}
	aver=sum/peopleNum*0.618;
	System.out.println("aver="+aver);
	this.findWinner(inputMap, scoreMap, aver);
	this.show(scoreMap);
	System.out.println("第一轮结束");
	for(int i=0;i<time-1;i++){
			sum=0.0;
			System.out.println("请输入第"+(i+2)+"轮的分数:");
			Iterator iter = inputMap.entrySet().iterator();
			while (iter.hasNext()) {
				Map.Entry entry0 = (Map.Entry) iter.next();
				String key = (String) entry0.getKey();
				System.out.println(key+"输入第"+(i+2)+"轮分数:");
				Double score =scan.nextDouble();
				inputMap.put(key, score);//替换掉以前的分数
				sum+=score;
		}
			aver=sum/peopleNum*0.618;
			System.out.println("aver="+aver);
			this.findWinner(inputMap, scoreMap, aver);
			this.show(scoreMap);
		System.out.println("第"+(i+2)+"轮结束");
	}
    System.out.println("游戏结束"); } //找出每次分数最接近黄金点的 和最远的 最接近的加一分 最远的减一分 其余加零分(可能有相同的) public void findWinner(HashMap<String,Double> inputMap,HashMap<String,Double> scoreMap,Double aver){ Double temp; Double temp0; List<String> latest=new ArrayList<String>(); List<String> farthest=new ArrayList<String>(); Iterator iter = inputMap.entrySet().iterator(); Map.Entry entry = (Map.Entry) iter.next(); Double input = (Double) entry.getValue(); String key0 = (String) entry.getKey(); latest.add(key0); farthest.add(key0); //iter.hasNext(); temp0=temp=Math.abs(aver-input); //遍历map while (iter.hasNext()) { entry = (Map.Entry) iter.next(); String key = (String) entry.getKey(); input = (Double) entry.getValue(); Double temp1=Math.abs(aver-input); if(temp>temp1){//寻找最近 temp=temp1; latest.clear(); latest.add(key); }else if(temp==temp1){ latest.add(key); } if(temp0<temp1){//寻找最远 temp0=temp1; farthest.clear(); farthest.add(key);} else if(temp0==temp1){ farthest.add(key); } } //实现加分 iter = scoreMap.entrySet().iterator(); while (iter.hasNext()) { Map.Entry entry0 = (Map.Entry) iter.next(); String key = (String) entry0.getKey(); Double score =(Double) entry0.getValue(); if(this.containList(key, latest)){ score=score+1; scoreMap.put(key, score); } if(this.containList(key, farthest)){ score=score-1; scoreMap.put(key, score); } } } public boolean containList(String str,List<String> list){ for(int i=0;i<list.size();i++){ if(str.equals(list.get(i))){ return true; } } return false; } public void show(HashMap<String,Double> scoreMap){ System.out.println("得分情况:"); Iterator iter = scoreMap.entrySet().iterator(); while (iter.hasNext()) { Map.Entry entry0 = (Map.Entry) iter.next(); String key = (String) entry0.getKey(); Double score =(Double) entry0.getValue(); System.out.println(key+":"+score); } } }
