错误消息: java.lang.ArithmeticException: /在survey.results(survey.java:51)处为零

Question

你可以从"//“部分看出我做错了什么，我尝试过不同的方法：

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);
    }
}

这就是我最后所做的，解决了错误。感谢大家的及时回复！

/**

 */ 

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

我对public void results(double total)进行了修改，使其接受一个double，并且成功地运行了。

你确定这是你所有的代码吗？
