Java第二个静态方法不执行

我无法弄清楚第二种方法无法执行的原因。它编译并接受输入,但之后没有任何反应。有人能指出我正确的方向吗?

import javax.swing.JOptionPane;

public class Test1 {
    public static void main(String[] arg) { 
        String hoursOfWorkString, costOfMaterialsString, nameOfProductString;

        nameOfProductString = JOptionPane.showInputDialog(null, "Enter the name of the product. ", JOptionPane.QUESTION_MESSAGE);   
        hoursOfWorkString = JOptionPane.showInputDialog(null, "Enter the number of hours worked. ", JOptionPane.QUESTION_MESSAGE); 

        double hoursOfWork = Double.parseDouble(hoursOfWorkString);

        costOfMaterialsString = JOptionPane.showInputDialog(null, "Enter the cost of the product. ", JOptionPane.QUESTION_MESSAGE);           
        double costOfMaterials = Double.parseDouble(costOfMaterialsString);
    }



    public static void CalulatePrice(double costOfMaterials, double hoursOfWork, String nameOfProductString) {
        double salePercentage = 0.75, shipping = 6, markup = 14, retailPrice;

        retailPrice = salePercentage * (costOfMaterials + (markup * hoursOfWork)) + shipping; 

        JOptionPane.showMessageDialog(null, String.format("The retaill price of the %. product is $ %.02f.", nameOfProductString, retailPrice));
    }
}

更新:我使用了该示例并修复了一些其他错误并运行。阅读评论后,我认为它不会起作用。我只知道我的代码出了点问题。

感谢大家的意见。

那是因为你已经定义了你的功能,但你还没有调用它。在main方法的末尾插入一个电话,例如

double costOfMaterials = Double.parseDouble(costOfMaterialsString);
// Here...
CalulatePrice(costOfMaterials, hoursOfWork, nameOfProductString);

,我认为您意味着 计算。并且, 遵循Java命名约定,它应该类似于calculatePrice
