Referring to variables

Question

If I have a class like this :
public class Thing
public Thing()
JLabel label = JLabel("label");
}How do I refer to the label from outside of the constructor method?
For instance if I make a Thing object in another class and want to change the label to "tree"

Answer 1

The variable must be a member variable if you want to access it from outside the constructor.
Example:public class Thing
    JLabel label;
    public Thing()
        label = JLabel("label");
}
