How do I access variables from the main class from another class (java)?

Question

I\'m making a cookie clicker clone in java to practice my java skills and I have a small problem, I have variables that are declared in the main method that I want to access

Answer 1

You would have to make the variables public class variables instead of method variables, thereby increasing the scope and visiblity of the variables. Like so:

public class ActionClass {
{
    public string MyPublicVariable = "woot";

    @Override
    public void actionPerformed(ActionEvent e) {


        ...
    }
}

A more popular/recommended way to do this is to use a getter/setter instead of making the variable explicitly public. You would access a private variable through public methods like so:

public class ActionClass {
{
    @Override
    public void actionPerformed(ActionEvent e) {

        private string MyPublicVariable = "woot";

        public void setMyString(string newString){
            MyPublicVariable = newString;
        }

        public string getMyString(){
            return MyPublicVariable;
        }
    }
}

This way, you have more control over what your variables are set to.
