Simple import problem

I'm trying to learn java and seem to be missing something obvious.

In subdirectory lab I have the file Play.java

package lab;
import java.io.*;

public class Play {
    public static void playprint(Object obj) {
        System.out.println(obj);
    }
}

My CLASSPATH starts with '.'

In the parent directory I have a program

public class test {
    public static void main(String[] args) { 
       lab.Play.playprint("hello world");
   }
}

This runs fine. If I change the program to 

import lab.Play.*;

public class test {
    public static void main(String[] args) { 
        playprint("hello world");
    }
}

It fails with an error that it can't find symbol method playprint

What am I missing?

If you want to skip using static methods, you can create an object of Play class inside the class test and then call playprint.

To import a method you have to use import static. Without you are trying to import all classes (and interfaces) within your class "Play" only.

import static lab.Play.*;

See the documentation on static imports for details.
