Question

我是Java的初学者，我的教授希望我们创建一个涉及数学的程序。问题是他想要一个单独的方法进行计算。有人可以帮帮我吗。由于某种原因，程序不会运行结果。我试着环顾这个网站，找不到答案。以下是代码：

import javax.swing.JOptionPane;

public class forFun {
    public static void main(String[] args)
    {
        double x, y, z;
        String xVal, yVal, zVal;
        xVal = JOptionPane.showInputDialog("Enter first integer: ");
        yVal = JOptionPane.showInputDialog("Enter second integer: ");
        zVal = JOptionPane.showInputDialog("Enter third integer: ");

        x = Double.parseDouble(xVal);
        y = Double.parseDouble(yVal);
        z = Double.parseDouble(zVal);

        System.exit(0);
    }

    public static void sumOfStocks(double x, double y, double z)
    {
        double result = x * y * z;

        System.out.println("The product of the integers is: " + result);
        System.exit(0);
    }
}

以下是代码应该如何

的示例

import javax.swing.JOptionPane;

public class forFun {
public static void main(String[] args)
{
    double x, y, z;
    String xVal, yVal, zVal;
    xVal = JOptionPane.showInputDialog("Enter first integer: ");
    yVal = JOptionPane.showInputDialog("Enter second integer: ");
    zVal = JOptionPane.showInputDialog("Enter third integer: ");

    x = Double.parseDouble(xVal);
    y = Double.parseDouble(yVal);
    z = Double.parseDouble(zVal);
    double result = sumOfStocks(x, y, z);
    System.out.println("The result is %d", result);
    System.exit(0);
}

public static double sumOfStocks(double x, double y, double z)
{
    double result = x * y * z;
    return result;

}
}
