java猜謎遊戲運行但無法正常運行

無法弄清楚我在做java猜謎遊戲程序時做錯了什麼。計算機從1到100之間選擇一個數字，並要求用戶猜測它。用戶被提示的太低或太高，並要求再次猜測，直到他們正確。我的問題是，當你猜數字的時候，它總是會說得太低，但是如果你再次輸入相同的數字，它會說正確的。java猜謎遊戲運行但無法正常運行

你做了什麼來調試它??? –

else //If guess<housePick

你錯了。在上述情況下，它相當於guess <= housePick。它必須是

else if(guess < housePick)

此外，繼在housePick == guess所以沒有做guess = input.nextInt()的點，你可以簡單地說你贏了被執行的代碼塊。

}while (guess != housePick); //while guess doesnt = housePick... 

    // At this point, guess == housePick, why ask for input again???? 

     // guess = input.nextInt(); 
     //save entered number as guess 

    //guesses = guesses + 1;

哇。不能相信我不能指出這一點。 – user2809114

@ user2809114發生這樣的事情。快樂編碼:) – TheKojuEffect

讓我們看看

Housepick = 87

猜測= 87

if ((guess + 10) >= housePick) //AND if guess is close to housePick 
{ 
     System.out.println ("close, but too low.") ; 
     //then print "close, but too low" 

     guesses = guesses + 1; 

}

HMM的87 + 10比87

更大然後它打破了DO /而循環，並再次提示您

你也有一個額外的input.nextInt（）在一段時間後：

}while (guess != housePick); //while guess doesnt = housePick... 

guess = input.nextInt(); 
//save entered number as guess

刪除它
