Java编写的苹果机游戏，以前，别说这个了，就几段代码都写不出来啊，还拿记事本写呢

import java.util.Scanner;

public class Apple {
static long score = 100;
// 使用常量表示水果种类
static final int FRUIT_SORT = 6;

static Scanner sc = new Scanner(System.in);

public static void main(String[] args) {
displayClient();
}

// 显示游戏主界面
public static void displayClient() {
  System.out
    .println("----------------------------------------------------------");
  System.out.println("当前积分：" + score + " 分");
  System.out.println("1> 苹果   [2倍]");
  System.out.println("2> 橙子   [3倍]");
  System.out.println("3> 西瓜   [5倍]");
  System.out.println("4> 芒果   [8倍]");
  System.out.println("5> 茄子   [10倍]");
  System.out.println("6> 白菜   [20倍]");
  // 输入所押的积分，并判断其合理性
  long inputPledge = inputPledge();
  // 输入所押的积分，并判断其合理性
  int inputFruit = inputFruit();
  int rightAnswer = (int) (Math.random() * 7 + 1);
  System.out.print(">>>>>>>>>>>>>>>>>>> ");
  System.out.println(getFruitName(rightAnswer) + "!!!!!");
  if (rightAnswer != inputFruit && score != inputPledge) {
   System.out.println("您损失了" + inputPledge + "积分！继续努力!!!!!!!!!");
   score -= inputPledge;
  } else if (rightAnswer == inputFruit) {
   System.out.println("恭喜恭喜…….. 您得到了" + inputPledge
     * getTimes(inputFruit) + "积分!!!!");
   score = (score + inputPledge * getTimes(inputFruit));
  } else if (score == inputPledge) {
   System.out.println("您损失了" + inputPledge + "积分！");
   System.out.println("游戏结束!!!!!!!!!!!!!");
   return;
  }
  displayClient();
}

// 输入所押的积分
public static long inputPledge() {
  System.out.print("请输入所押的积分：");
  long input = sc.nextLong();
  if (input > score) {
   System.out.println("您当前没有这么多的积分哦! ^_^ ");
   input = inputPledge();
  } else if (input <= 0) {
   System.out.println("对不起，输入的积分必须是正整数哦！！！");
   input = inputPledge();
  }
  return input;
}

// 输入所猜的水果
public static int inputFruit() {
  System.out.print("请选择所押的水果种类：");
  int input = sc.nextInt();
  if (input > FRUIT_SORT) {
   System.out.println("没有这样的水果，请确定后重新输入！");
   input = inputFruit();
  }
  return input;
}

// 根据水果的号码，判断水果的名字

public static String getFruitName(int number) {
  String s = "";
  switch (number) {
  case 1:
   s = "苹果";
   break;
  case 2:
   s = "橙子";
   break;
  case 3:
   s = "西瓜";
   break;
  case 4:
   s = "芒果";
   break;
  case 5:
   s = "茄子";
   break;
  case 6:
   s = "白菜";
   break;
  case 7:
   s = "通吃";
   break;
  }
  return s;
}

// 根据水果的号码，判断赢了之后，获得积分的倍数
public static long getTimes(int number) {
  long times = 1;
  switch (number) {
  case 1:
   times = 2;
   break;
  case 2:
   times = 3;
   break;
  case 3:
   times = 5;
   break;
  case 4:
   times = 8;
   break;
  case 5:
   times = 10;
   break;
  case 6:
   times = 20;
   break;
  }
  return times;
}
}
记事本写代码确实挺能锻炼人的，慢慢就把语法规则掌握了，看看那自己写的程序，心里挺有成就感的。
