运行结果：
定义数组a存要显示的字幕，数组长度为n，生成0到n-1的随机数r，接受用户输入字符c，比较c和a[r]，记录用户猜的次数，3次后不能继续

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

do{

System.out.println("输入C:"+c);
for (int i = 0; i 4; i++) {
System.out.println("请输入一个大写字母：");
String at = in.next();
System.out.println(at);

}else {

}
}
System.out.println("是否继续：y/n");

}while("y".equals(yn));
System.out.println("你结束了猜字母的游戏！");
}
}
//直接粘贴，复制，就能运行。
import java.util.Random;

System.out.println(sb);

if(index=0){
if(sb.charAt(2*index)=='_'){
guessString.setCharAt(index, '*');
sb.setCharAt(index*2, c);
numberGuessed++;
}
}
System.out.println(sb);
}
}
}
代码如下：猜的次数和单词长度一样。
import java.util.* ;
public class T {
public static void main(String [] args) {
Scanner scanner=new Scanner(System.in);
String word;
String s;
String s1="";
String s2="";
char c;
System.out.println("Please enter a word:");
word=scanner.next();
s1=word;
for(int i=0;is1.length();i++)
s2=s2+"*";
for(int i=0;iword.length();i++){
System.out.println("Please enter a letter:");
s=scanner.next();
if(s.length()1){
System.out.println("Error!");
i--;
}else{
c=s.charAt(0);
int index=s1.indexOf(c);
if(index!=-1){
s2=s2.substring(0,index)+c+s2.substring(index+1);
s1=s1.substring(0,index)+"0"+s1.substring(index+1);
}
System.out.println(s2);
if(word.length()-i-10)
System.out.println("You have "+(word.length()-i-1)+" more tries");
}
}
if(s2.equals(word)){
System.out.println("You Win!");
}else
System.out.println("The answer is"+word+".You Lose!");
}
}
运行结果：
Please enter a word:
hello
Please enter a letter:
o
****o
You have 4 more tries
Please enter a letter:
h
h***o
You have 3 more tries
Please enter a letter:
l
h*l*o
You have 2 more tries
Please enter a letter:
l
h*llo
You have 1 more tries
Please enter a letter:
e
hello
You Win!
