I have an interface implemented by 2 abstract class, and I have to extends these class in a sub-package, but I don't know how to do it.

I have my class 1 in a package (summarized) :

package com.p1;

abstract class Class1 implements InterfaceTest{
    private int x;

    public Class1(int x){
    }
}

And my second class in a sub-package :

package com.p1.subPackage;

import com.p1.Class1; //which is not working cause its abstract

public class Class2 extends Class1{
    public Class2(){
        x = 5;
    }
}

How I am supposed to import this class?

    It's not working because the class isn't `public`, not because the class is abstract. Having no visibility modifier means it's package-private. In other words, it's only visible to classes within the same package. – Slaw Mar 30 '19 at 02:35
