Question

这是从编程课的介绍，不幸的是我的导师根本没有帮助，所以我正在寻求专业人士的帮助。我使用最新的JDK版本。感谢任何可以提供帮助的人。

import java.util.Scanner; //the error here reads : incorrect package. but im in the correct package

package calculate.a.tip.ricardo.penaloza; // the error here reads: class,interface or enum expected

public class CalculateATipRicardoPenaloza 
{


    public static void main(String[] args)
    {
        Scanner input = new Scanner (System.in);
        System.out.println("Enter a number for radius");
        double radius = input.nextDouble();

        double area = radius * radius * 3.14;

        System.out.println("The area for the circle of radius" +
                radius + "is" + area);
    }

}
