<p>In java parent package class accessible from child packge class? please explain me any one?</p>

<p>example
package A.A1.A2 contains class sub
package A contains class sup</p>

<p>Is there anyway to access sup from sub?</p>

<p>pls explain.</p>

<p>i tried import it won't work
Example:
before the program Directory Structure is 
package1 contains package1.java --> package2 --> package3 contains PCheck.java</p>

<pre><code>//package1.java
package package1;
public class package1{
    public static void main(String[] args) {

    }
}
class phelo{
    phelo(){
        int a;
        System.out.println("hai fun freom package 1");
    }
}

//PCheck.java;
package package1.package2.package3;
import package1.*;   //to import package1.java
public class PCheck {
    public static void main(String[] args) {
        phelo obj=new phelo();
    }
}
class helo{
    helo(){
        int a;
        System.out.println("hai fun from package 3");
    }
}
</code></pre>

<p>output:
compile time error:package package1.package2.package3 doesnot exist;</p>

<p>for import class from different directory we use import statements but here we need access parent package from subpackage.i tried import  it won't work  pls explain with an example.</p>
