java刽子手小游戏代码，谁能帮我看下，注释一下，本人小白，讲清楚点哦。
import java.util.Scanner;
//引入包
public class Exercise9_31 {
public static void main(String[] args) {
String[] words = { "write", "program", "that", "receive", "positive" };
//创建一个string 数组
char anotherGame;
Scanner input = new Scanner(System.in);
//新建一个Scanner对象 用于读取用户输入
do {
//do while loop,用户输入Y就一直执行
int index = (int) (Math.random() * words.length);
//生成0-4之间的一个随机数
String hiddenWord = words[index];
//根据生成的随机数 选定hiddenword也就是你要猜的单词
StringBuilder guessedWord = new StringBuilder();
//新建一个StringBuilder对象 用来猜单词
for (int i = 0; i hiddenWord.length(); i++)
guessedWord.append('*');
//先将要猜的单词以全部星号形式显示
int numberOfCorrectLettersGuessed = 0, numberOfMisses = 0;
//两个整数 记录猜对的字母数 和猜错的字母数
while (numberOfCorrectLettersGuessed hiddenWord.length()) {
//只要还没才出来 就一直执行
System.out.print("(Guess) Enter a letter in word " + guessedWord
+ " ");
//打印消息 让用户输入
String s = input.nextLine();
char letter = s.charAt(0);
//这两句读取用户输入的字母
if (guessedWord.indexOf(letter + "") = 0) {
//如果这个字母已经显示了，已经猜过并且出现在要猜的单词里面（没有出现的话 index会是-1）
System.out.println("\t" + letter + " is already in the word");
} else if (hiddenWord.indexOf(letter) 0) {
//如果单词里面没这个单词
System.out.println("\t" + letter + " is not in the word");
numberOfMisses++;
//猜错的数加一
} else {
int k = hiddenWord.indexOf(letter);
//最后一种情况 就是这个字母猜中了某个位置
while (k = 0) {
guessedWord.setCharAt(k, letter);
//把这个字母替代星号 放到单词中
numberOfCorrectLettersGuessed++;
//猜对的字母加一
k = hiddenWord.indexOf(letter, k + 1);
}
}
}
System.out.println("The word is " + hiddenWord + ". You missed "
+ numberOfMisses + ((numberOfMisses = 1) ? " time" : " times"));
System.out.print("Do you want to guess for another word? Enter y or n ");
anotherGame = input.nextLine().charAt(0);
} while (anotherGame == 'y');
}
}
如何在JAVA语言中设置代码,输出X=1 X=2
这个分两种情况：
1.你要直接原样输出，那么就在主方法main()中写如下代码：
System.out.println("X=1
X=2");
因为println方法里，双引号括起来的内容会原样输出
2.你要动态输出，就是X=？不是固定的，那么就要先定义一个变量x，然后输出，代码如下：
int
x=1;
System.out.println("X="+x);
当然了，x还可以等于2，等于3，这样就可以随便输出任何你想要的数字了。
不知道有没有解决你的问题
跪求用java设计的“炮台射击游戏”程序代码
有现成java按x射击代码的java按x射击代码，自己去下吧
java 射击游戏中的追踪导弹怎么写？请高手说下，3Q！
开一个线程获取java按x射击代码你要追踪的目标的坐标java按x射击代码，让炸弹以你定义的线向坐标靠近java按x射击代码，线可以是直的或者曲线随你。
Java 求一段射击小游戏的代码(让一个小图片随机出现)
1、在JFrame上用网格布局批量实例化一些JLabel 2、建立一个线程获得一个随机数java按x射击代码，根据随机数给某个JLabel设置icon 3、线程sleep(1000); 4、移除这个JLabeljava按x射击代码的icon 5、线程循环
求java做动画代码
