How to access parent class integer variable in child class? [duplicate]

Question

I am trying to access int a= 10 variable in child class but getting error:

Cannot make a static reference to the non-static field FreshJuice.a

Following is my code.

class FreshJuice {
    enum FreshJuiceSize{SMALL,MEDIUM,LARGE};
    FreshJuiceSize size;
    int a   =   10;
}

public class Index extends FreshJuice {

    enum programmingLanguage{PHP,Java,Dotnet,HTML};

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        System.out.println(FreshJuice.FreshJuiceSize.SMALL);
        System.out.println(programmingLanguage.PHP);
        System.out.println(FreshJuice.a); //getting error in this line
    }

}

I want to directly access int variable of FreshJuice class in child class. How can i achieve this target?

Why are you being abstract and secretive? You got an error. Tell us exactly what error you got. But, before you do that, check that others haven't had the same error. (Hint: they have.) — Sotirios Delimanolis

First create an instance of FreshJuice class:

FreshJuice fj = new FreshJuice();

Now you can access the variable a .

But if you set your variable as private int a=10; Then you can't access that still. That's why it is good practice to use getter and setter methods to access those private variables.
