怎么样用java编写下面的猜字游戏程序，我们刚刚学，代码不要太难

import java.util.Scanner;

public class Test {

    public static void main(String[] args) {
        int guessTime = 8;
        boolean restart = true;
        while (restart) {
            System.out.println("请选择下列选项！");
            System.out.println("1 ----开始猜数");
            System.out.println("2 ----游戏参数设置");
            System.out.println("9 ----退出");
            boolean flag = true;
            String choose = null;
            Scanner in = null;
            while (flag) {
                in = new Scanner(System.in);
                choose = in.next();
                if (!choose.matches("[129]")) {
                    System.out.println("输入错误，请重新输入");
                    continue;
                } else {
                    break;
                }
            }
            if ("2".equals(choose)) {
                boolean chooseLevel = false;
                System.out.println("请选择游戏难度！");
                System.out.println("1 ----难(4次)");
                System.out.println("2 ----一般(6次)");
                System.out.println("3 ----容易(8次)");
                while (!chooseLevel) {
                    String s = in.next();
                    if (s.matches("[123]")) {
                        switch (Integer.parseInt(s)) {
                        case 1:
                            guessTime = 4;
                            chooseLevel = true;
                            break;
                        case 2:
                            guessTime = 6;
                            chooseLevel = true;
                            break;
                        case 3:
                            guessTime = 8;
                            chooseLevel = true;
                            break;
                        default:
                            System.out.println("你输入的选择不存在(请输入1、2、3)");
                            break;
                        }

                    } else {
                        System.out.println("你输入的选择不存在(请输入1、2、3)");
                    }
                }
                continue;
            }
            if ("9".equals(choose)) {
                System.exit(0);
            }
            if ("1".equals(choose)) {
                String number = String.valueOf(Math.round(Math.random() * 100) + 1);
                System.out.println(number);

                boolean getIt = false;
                int count = 0;
                while (!getIt && ++count <= guessTime) {
                    System.out.println("请输入你猜的值(1-100)");
                    String s = in.next();
                    if (s.matches("\\d+")) {
                        try {
                            if (Integer.parseInt(s) == Integer.parseInt(number)) {
                                getIt = true;
                                break;
                            } else if (Integer.parseInt(s) > Integer.parseInt(number)) {
                                System.out.println("你输入的数字大了！");
                            } else {
                                System.out.println("你输入的数字小了！");
                            }
                        } catch (NumberFormatException e) {
                            System.out.println("你输入的数据超过Integer的最大范围！");
                            continue;
                        }
                    } else {
                        System.out.println("你输入的数据不合法！");
                        continue;
                    }
                }
                if (getIt) {
                    System.out.println("恭喜你猜对了，你的战斗力是" + Math.round((1 - count * 1.0 / guessTime) * 100) + "%");
                } else {
                    System.out.println("超过次数,尚需努力");
                }
                in.nextLine();
                in.nextLine();
            }
        }

    }
}

这是详细代码，建议楼主多加研习，修成正果~~

那么多判断，真不是分的问题了。
