import java.util.*;
import java.util.Scanner;
public class Prac2
{
   public static void main(String[] args)
   {
       Scanner sc =  new Scanner(System.in);
       do
       {
           String guess;
           int wL=0;
           char hidden='r';
           char gchar;
           System.out.println("enter your word, stop to end.");
           guess = sc.nextLine();
           wL = guess.length();
           while(guess != 'stop')
           {
               for(int i=0;i<wL;i++)
               {
                   gchar=guess.charAt(i);
                   if(gchar = hidden)
                   {
                       System.out.println("Your guess does not contain the secret letter");
                       System.out.println("enter next word, stop to end.");
                       guess = sc.nextLine()
                   }
                   else
                   {
                       System.out.println("Your guess contains the secret letter");
                       System.out.println("enter next word, stop to end.");
                       guess = sc.nextLin()
                   }
               }
           }
       }
   }

推 zhengdavy:查看看字串比較跟判斷式的運算子
→ zhengdavy:for loop裡有問題, 你試試看自己一行一行走一遍
→ zhengdavy:看不懂你是在寫do while loop還是while loop
推 ayumi001:if(gchar = hidden) 編譯錯誤 要"兩"個等號才會是boolean
→ MiaShopgirl:看起來是猜字遊戲.. 請參考 http://goo.gl/Z5wl0
推 darkk6:關鍵字，查一下：字串、字元常數、字串的比較、比較運算子
→ hoby:謝謝大家  我會再研究看看^^
推 waterleader:基本語法就有很多問題。
