Question

在我的Tafe工作中，我必须设置它，以便我的Java程序询问用户他们的名字和他们的成绩点平均值，然后将所述平均值乘以10，并显示结果。目前我的代码看起来像这样

public static void main(String[] args)
{

    Scanner sc = new Scanner(System.in);
    String Name;
    String gradePoint;

    Name=JOptionPane.showInputDialog(null, "Please enter your name.", "Input Name", JOptionPane.QUESTION_MESSAGE);
     gradePoint = JOptionPane.showInputDialog(null, "What is your grade point average?", "Grade point average", JOptionPane.QUESTION_MESSAGE);
    System.out.println("Your name is " + Name + ", and your grade point average is " + gradePoint + ", so your book store credit is " + Integer.parseInt(gradePoint)*10);

}

我认为这在公理上是错误的，但我仍然是Java的新手。请告诉我必须做出的任何和所有改变。

我采用了你的代码并制作了一个仅使用对话框的工作版本。扫描仪输入上没有System.out。从您的评论中，您似乎正在使用JavaFX项目。这不是JavaFX代码，只是常规应用程序......

public static void main(String[] args) throws Exception {
    String name = JOptionPane.showInputDialog(null,
            "Please enter your name.", "Input Name", JOptionPane.QUESTION_MESSAGE);
    String gradePointString = JOptionPane.showInputDialog(null,
            "What is your grade point average?", "Grade point average", JOptionPane.QUESTION_MESSAGE);
    int gradePoint = Integer.parseInt(gradePointString);
    int x = 10;
    JOptionPane.showConfirmDialog(null,
            "Your name is " + name + ", and your grade point average is " + gradePoint +
            ", so your book store credit is " + (gradePoint*x));
}

如何将值传递给将所述值乘以10的方法？
