java stringvars是什么意思？

Question

我是Java初学者，我想问一个问题 包 stringvars 在Java中是什么意思？

package stringvars;
import java.util.Scanner;
public class myProg{
    public static void main(String[] args)
    {
        Scanner user_input = new Scanner(System.in);

        String first_name; //packge stringvars
        System.out.print("Kindly Enter your first name: ");
        first_name = user_input.next();

        String family_name; //packge stringvars
        System.out.print("Enter your family name: ");
        family_name = user_input.next();

        String full_name; //packge stringvars
        full_name = first_name + " " + family_name;

        System.out.println("I Guess you are " + full_name);

    }

}

并且当我尝试运行Java时也出现错误

由于您将软件包声明为

package stringvars;

您的Java类应位于 stringvars 文件夹中。比您可以尝试编译和运行。
