這段java代碼有什麼問題？

-4

如果有人能夠發現此代碼中的錯誤，它將幫助我一噸。我正在使用Eclipse，並且我正試圖製作一個程序，只需按一下按鈕即可吐出單詞/句子。如果您需要更多信息，請詢問。這段java代碼有什麼問題？

ERROR：「如果（this.boverall [α]！= 0）{」，ERROR消息「操作員=未定義的參數類型（一個或多個）的布爾，INT！」

public String sentenceOverall() 
    { 
    ArrayList<String> toBeUsed = new ArrayList(); 
    for (int a = 0; a < this.soverall.length; a++) { 
     if (this.boverall[a] != 0) { 
     toBeUsed.add(this.soverall[a]); 
     } 
    } 
    if (toBeUsed.size() == 2) 
    { 
     int sentencePattern = rand.nextInt(10); 
     if (sentencePattern < 9) 
     { 
     String[] OverallOptions = { " The song is overall both ", " Overall, the song is both ", " This song, overall, is both ", " Your song is quite ", " I think that the song is ", " I believe that your song is both ", " Your song is without a doubt ", " In my point of view, this is ", " First of all, thank you for creating this song. This song is very ", " Judging from my position, this song is ", " Personally, I think that the song is ", " All things taken together, I would say that this song is " };

什麼是'boverall'數組？ – BitNinja

說實話，我不知道。我發現了一種我想上網的程序，我正在編輯它，因此它吐出了我想要的單詞，但在此之前，我需要修復所有代碼錯誤。 – user3856445

是唯一的一段代碼？ –

它似乎boverall是一個boolean陣列。試試這個：

if (this.boverall[a])

我是如何達到這種狀態的？讓我們來看看，一步一步：

this.boverall[a] != 0  // this is wrong, can't compare int with boolean 
this.boverall[a] != false // this is what you really meant to write 
this.boverall[a] == true // if it's not false, then it can only be true 
this.boverall[a]   // equivalent to the above line, but shorter

記住，在Java（不像其他編程語言）一boolean是不一個整數，特別是0不一樣false。

非常感謝你，我還是新手，你解決了我的所有問題。<3謝謝你的每一個人 – user3856445

這看起來與OP想要的完全相反。他們正在測試它是否爲非零，通常相當於真。 – McLovin

注意詳細說明，就好像（！this.boverall [a]）似乎不起作用 – user3856445
