Why is my score variable not assessable outside my GameScreen class?

Question

DIFFERENT CLASSES

package battleship;


public class GameSum extends javax.swing.JFrame {


    public GameSum() {
        initComponents();
        J_time.setText(score);
    }



package battleship;

public class GameScreen extends javax.swing.JFrame {


    protected int score;

    public GameScreen() {
        initComponents();

    }   
private void B_checkActionPerformed(java.awt.event.ActionEvent evt) {                                        

       if (score < getHS(0) && score < hs[1])  {setHS(0, score, nickname);  }
       for (int loop = 0; loop<5; loop++)
       {
       if(score > hs[loop] && score < hs[loop+1]) {setHS(loop+1, score, nickname); }   
       }
    }

Because your variable is not public, or doesn't have a public getter available.

In Gamescreen just do:

public int getScore() {
    return score;
}

And call this function in GameSum.

By the way, I don't want to sound rude, but if this is your real indentation/code convention, it is really unredeable. Try to indent properly, put the content of a if on a new line if you use braces, or on the same line without braces if it is a one line block. Just my two cents.

You should lean about access modifiers presidency in Java. You have to create a way to access your variable(create public seter and public getter) or make variable public.

Follow this link to refer about access modifiers.

Your score variable is protected, which mean it is only can access by (Gamescreen)it childs classes and classes on same package and please go through on this https://stackoverflow.com/a/215505/2291134

I started with it as a public variable and it didn't work, anyway the score variable is in the same package so it should be accessible from another class in the same package but it isn't. – David Boulton Sep 11 '13 at 12:59
