我是新來這個網站，以及Java。條件內條件java

任何人都可以幫助我找出爲什麼即使沒有紅點，程序的某些部分仍然無法工作？

我把註釋使用/ /行不工作。

import javax.swing.JOptionPane; 

public class ChatterBot { 

public static void main(String[] args) { 
    // TODO Auto-generated method stub 
    String firstName, work, sex = null; 
    int age; 
    firstName = JOptionPane.showInputDialog("Hello, my name is Chatterbox. What is your name?"); 
    if (firstName.toLowerCase().contains("name".toLowerCase())) { 
     JOptionPane.showMessageDialog(null, "Welcome " + firstName.substring(firstName.lastIndexOf(" ") + 1) + "!"); 
     sex = JOptionPane.showInputDialog(null, "Is " + firstName.substring(firstName.lastIndexOf(" ") + 1) 
       + " a guy name or a woman name? (type stop to end conversation)"); 
    } else { 
     JOptionPane.showMessageDialog(null, "Welcome " + firstName + "!"); 
     sex = JOptionPane.showInputDialog(null, 
       "Is " + firstName + " a guy name or a woman name (type stop to end conversation)"); 
    } 

    while (true) 
     if (sex.toLowerCase().contains("guy".toLowerCase())) { 
      JOptionPane.showMessageDialog(null, "Welcome friend"); 
      work = JOptionPane 
        .showInputDialog("Would you like to talk about work or do you want to hear a cool story?"); 
      if (work.toLowerCase().contains("work".toLowerCase())) { 
       JOptionPane.showMessageDialog(null, "Interesting"); 
       break; 

      } else if (work.toLowerCase().contains("story".toLowerCase())) { 
       JOptionPane.showMessageDialog(null, "hola"); 
       break; 
      } else if (sex.toLowerCase().contains("woman".toLowerCase())) { 
//when I type woman nothing happens but the else if below for "stop" works. 
       age = Integer.parseInt(JOptionPane.showInputDialog(null, "How old are you?")); 
       if (age >= 18 && age <= 40) { 
        JOptionPane.showMessageDialog(null, "Dayummm"); 
       } else if (age > 40) { 
        JOptionPane.showMessageDialog(null, "I don't like no cougar!"); 
       } else { 
        JOptionPane.showMessageDialog(null, "I ain't no pedo. Bye!"); 
       } 
      } 

      break; 
     } else if (sex.toLowerCase().contains("stop".toLowerCase())) { 
      JOptionPane.showMessageDialog(null, "Have a nice day."); 
      break; 
     } else { 
      JOptionPane.showMessageDialog(null, "Goodbye"); 
      break; 
     } 
}

調試器可以幫助您 – Jens

抱歉，這不是一個「我們調試程序爲您」的服務。而且你知道什麼有幫助：當加入一個*新的地方時，你首先了解那個地方的規則，而不是盲目地傾銷內容。從這個意義上說：請A）刪除這個「問題」B）閱讀[幫助]並學習如何問一個更好的問題;-) – GhostCat

歡迎來到堆棧溢出！尋求調試幫助的問題（「爲什麼這個代碼不工作？」）必須包含所需的行爲，特定的問題或錯誤以及在問題本身中重現問題所需的最短代碼。沒有明確問題陳述的問題對其他讀者無益。請參閱：如何創建[mcve]。使用「編輯」鏈接來改善你的*問題* - 不要通過評論添加更多信息。謝謝！ – GhostCat

你的if語句不按順序，你缺少一個字符}關閉，如果和刪除}

} else if (sex.toLowerCase().contains("woman".toLowerCase())) { 
//when I type woman nothing happens but the else if below for "stop" works. 
       age = Integer.parseInt(JOptionPane.showInputDialog(null, "How old are you?")); 
       if (age >= 18 && age <= 40) { 
        JOptionPane.showMessageDialog(null, "Dayummm"); 
       } else if (age > 40) { 
        JOptionPane.showMessageDialog(null, "I don't like no cougar!"); 
       } else { 
        JOptionPane.showMessageDialog(null, "I ain't no pedo. Bye!"); 
       } 


      break; 
     }

還建議：引入變量來防止重複碼

String sex = sex.toLowerCase() 
String work = work.toLowerCase()

您也可以刪除小寫字母的小寫字母（）作爲"story".toLowerCase()

我沒有編寫編譯錯誤，只是修復了if語句。我會寫更多的細節 – user7294900

對不起，我不確定你的措辭 –

你if (sex.toLowerCase().contains("woman".toLowerCase()))塊嵌套在if (sex.toLowerCase().contains("guy".toLowerCase()))塊內，但他們應該在同一水平：

if (sex.toLowerCase().contains("guy".toLowerCase())) { 
     JOptionPane.showMessageDialog(null, "Welcome friend"); 
     work = JOptionPane 
       .showInputDialog("Would you like to talk about work or do you want to hear a cool story?"); 
     if (work.toLowerCase().contains("work".toLowerCase())) { 
      JOptionPane.showMessageDialog(null, "Interesting"); 
      break; 

     } else if (work.toLowerCase().contains("story".toLowerCase())) { 
      JOptionPane.showMessageDialog(null, "hola"); 
      break; 
     } 

     break; 
    } else if (sex.toLowerCase().contains("woman".toLowerCase())) { 
      //when I type woman nothing happens but the else if below for "stop" works. 
      age = Integer.parseInt(JOptionPane.showInputDialog(null, "How old are you?")); 
      if (age >= 18 && age <= 40) { 
       JOptionPane.showMessageDialog(null, "Dayummm"); 
      } else if (age > 40) { 
       JOptionPane.showMessageDialog(null, "I don't like no cougar!"); 
      } else { 
       JOptionPane.showMessageDialog(null, "I ain't no pedo. Bye!"); 
      } 
    } else if (sex.toLowerCase().contains("stop".toLowerCase())) { 
     JOptionPane.showMessageDialog(null, "Have a nice day."); 
     break; 
    } else { 
     JOptionPane.showMessageDialog(null, "Goodbye"); 
     break; 
    }
