錯誤消息：java.lang.ArithmeticException：/在survey.results處爲零（survey.java:51）

Question

我無法弄清楚我在這裏做錯了什麼;是你可以用「//」部分看到，我已經嘗試了不同的方式：

public class survey { 
    // instance variables - replace the example below with your own 
    private double total = 12467; 
    // private double percentage = 100; 
    private double one = total * .14; // percentage; 
    private double citrus = total * .64; // percentage; 

    public void results(int total) { 

     System.out.println("Number of people surveyed:" + total); 
     System.out.println("Number who purchase one or more energy drinks:" 
       + one); 
     System.out.println("Number who prefer citrus flavored energy drinks:" 
       + citrus); 
    } 
}

這是我落得這樣做，解決了這個錯誤。感謝大家的及時回覆！

    private int oneperc; 
    private int citrusperc; 
    { 
    oneperc = (int) ((total*one/100)); 
} 
    { 
    citrusperc = (int) ((total*citrus/100)); 
} 

public void results(int total) 
{ 
    System.out.println("Number of people surveyed:" + total); 
     System.out.println("Number who purchase one or more energy drinks:" + oneperc); 
      System.out.println("Number who prefer citrus flavored energy drinks:" + citrusperc); 
     } 
} 

Answer 1

我修改了public void results(double total)以接受double，並且它成功運行。

你確定這是你的所有代碼嗎？
