類與對(duì)象案例-童年回憶之打字游戲

一、玩家類
二、等級(jí)類
三、游戲類
四、等級(jí)地圖
五、測(cè)試類

這次要做的案例是一個(gè)打字游戲的案例，相信大家小時(shí)候都玩過(guò)金山打字通的警察抓小偷和飛機(jī)大戰(zhàn)，這次的案例是類似的簡(jiǎn)易版。

首先對(duì)于這個(gè)案例，我們要解決的是如何生成隨機(jī)的字符串，如何判斷生成的字符串和輸入的字符串是否相等。

一、玩家類

package com.yc.oop6.hc0705;

public class Player {
 private int score; //積分
 private long startTime; //各級(jí)別的開(kāi)始時(shí)間
 private long dis;   //每次闖關(guān)剩余時(shí)間
 private int levelNo; //級(jí)別號(hào)碼
 public int getScore() {
 return score;
 }
 public void setScore(int score) {
 this.score = score;
 }
 public long getStartTime() {
 return startTime;
 }
 public void setStartTime(long startTime) {
 this.startTime = startTime;
 }
 public int getLevelNo() {
 return levelNo;
 }
 public void setLevelNo(int levelNo) {
 this.levelNo = levelNo;
 }
 public Player(int score, long startTime, int levelNo) {
 super();
 this.score = score;
 this.startTime = startTime;
 this.levelNo = levelNo;
 }
 public Player() {
 super();
 }
 public long getDis() {
 return dis;
 }
 public void setDis(long dis) {
 this.dis = dis;
 }
 
 
}

二、等級(jí)類

package com.yc.oop6.hc0705;

public class Level {
 private int levelNo; //第幾關(guān)
 private int strLength; //字符串長(zhǎng)度
 private int strTime; //需要輸入的次數(shù)
 private int timeLimit; //時(shí)間限制
 private int score; //答對(duì)一次獲得的積分
 public int getLevelNo() {
 return levelNo;
 }
 public int getStrLength() {
 return strLength;
 }
 public int getStrTime() {
 return strTime;
 }
 public int getTimeLimit() {
 return timeLimit;
 }
 public int getScore() {
 return score;
 }
 public Level(int levelNo, int strLength, int strTime, int timeLimit, int score) {
 super();
 this.levelNo = levelNo;
 this.strLength = strLength;
 this.strTime = strTime;
 this.timeLimit = timeLimit;
 this.score = score;
 }
 public Level() {
 super();
 }
 
}

三、游戲類

package com.yc.oop6.hc0705;

import java.util.Random;
import java.util.Scanner;

public class Game {
 private Player player;
 private Random r = new Random();
 private Scanner sc = new Scanner(System.in) ;
 
 public Game(Player player) {
 this.player = player;
 }
 
 //開(kāi)始游戲
 public void startGame() {
 System.out.println("游戲開(kāi)始");
 
 //開(kāi)始闖關(guān)
 for(int i = 0; i < Levels.ls.length; i++) {
 System.out.println("開(kāi)始進(jìn)入第" + (i+1) + "關(guān)");
 //每一關(guān)的開(kāi)始在這里
 player.setLevelNo(player.getLevelNo() + 1);
 player.setStartTime(System.currentTimeMillis());
 
 //循環(huán)，這一關(guān)要輸入多少次
 
 for(int j = 0 ; j < Levels.ls[player.getLevelNo() - 1].getStrTime() ; j++ ) {
 String out = printStr();
 System.out.println(out);
 String in = sc.nextLine();
 
 boolean flag = result(in, out);
 if(flag == false) {
  System.exit(1);;
 }
 
 }
 //每剩下1s 增加20分
 player.setScore(player.getScore() + (int)player.getDis() * 20);
 System.out.println("完成第" + (i+1) + "關(guān)，您現(xiàn)在的積分為：" + player.getScore());
 
 System.out.println("進(jìn)入下一關(guān)");
 
 }
 }
 
 //隨機(jī)字符串
 
 public String printStr( ) {
 
 
 
 String str = "";
 double rNum = 0;
 
 
 for(int i = 0; i < Levels.ls[player.getLevelNo()-1].getStrLength(); i++ ) {
 rNum = r.nextDouble();
 if(rNum < 0.3333) {
 str += (r.nextInt(9)+1);
 }else if(rNum < 0.6667){
 str += (char)(r.nextInt(26)+65);
 }else {
 str += (char)(r.nextInt(26)+97);
 }
 }
 return str;
 }
 
 //字符串對(duì)比
 
 public boolean result(String in, String out) {
 //字符串判斷
 if(out.equals(in)) {
 //先獲取一下當(dāng)前的系統(tǒng)時(shí)間
 long endTimes = System.currentTimeMillis();
 long startTimes = player.getStartTime();
 //獲得下一關(guān)的時(shí)間
 long dis = Levels.ls[player.getLevelNo() -1 ].getTimeLimit();
 
 if((endTimes - startTimes)/1000 > dis) {
 System.out.println("游戲超時(shí)，游戲結(jié)束，您的最終得分為：" + player.getScore());
 return false;
 }else {
 //輸入正確，且沒(méi)有超時(shí)
 //加積分
 int score = Levels.ls[player.getLevelNo()].getScore();
 player.setDis(dis - (endTimes - startTimes)/1000); 
 player.setScore(player.getScore() + score );
 
 
 System.out.println("輸入正確，您現(xiàn)在的積分為："+ player.getScore() +" ，這一關(guān)您還有： " + player.getDis() + " 秒鐘");
 return true;
 }
 }else {
 System.out.println("輸入錯(cuò)誤，游戲結(jié)束，您的最終得分為：" + player.getScore());
 return false;//輸入錯(cuò)誤
 }
 
 
 }
}

四、等級(jí)地圖

package com.yc.oop6.hc0705;

public class Levels {
 //定義一個(gè)靜態(tài)的對(duì)象數(shù)組
 public static Level ls[] = new Level[7];
 
 static {
 ls[0] = new Level(1,2,5,20,10);
 ls[1] = new Level(2,3,5,18,20);
 ls[2] = new Level(3,4,4,16,30);
 ls[3] = new Level(4,5,4,15,40);
 ls[4] = new Level(5,6,4,15,50);
 ls[5] = new Level(6,7,3,15,60);
 ls[6] = new Level(7,8,3,15,70);
 }
}

五、測(cè)試類

package com.yc.oop6.hc0705;


public class Test {
 public static void main(String[] args) {
 
 Player p = new Player();
 Game g = new Game(p);
 g.startGame();
 
 

 }
}

詳細(xì)的解釋都在代碼的注釋里了，大家細(xì)品。
