cmd中的Java编程错误

Question

import PPP.*;
public class Main{

   public static void main(String args[]){
      PP obj=new PP();
      obj.Show();
   }
}

这个简单的程序会出错：

cannot access PP where PPP(Package) only contains a class file (PP.class) and it's on desktop
also Main.java is on desktop.

Answer 1

你必须在你的班级PP

中找到package PP;

这是您修改后的代码

package PPP;

public class PP
{

    public static void main(String...a)
    {
        System.out.println("hello");
    }
    public void show()
    {
    System.out.println("hello");
    }

}

这里是你的主要课程

import PPP.*;

public class Main{

   public static void main(String args[]){
      PP obj=new PP();
      obj.show();
   }
}

它会帮助你
