Calling a variable from a void method

Question

Hey this is a very simple question. Can I call a variable, in this case an array, from a void method? I have declared my arrays at the class level and initialized them in a void method. Not sure it I am doing this correctly but I am trying to call the array from another class. I am a beginner. Thank you for the help.

ex:

public class HeyThere{
    public double me[];

    public void yeahYou(int you){
        me = new me[69]
    }
}

Answer 1

Yes, since your class level array me is scoped as Public, you will be able to access it from another class after you instantiate the HeyThere class.

Ex:

public class HeyThereCaller
{
..
....
    public void SomeMethod()
    {
    ...
    ....
    HeyThere heyThereInstance = new HeyThere();
    double[] meArray = heyThereInstance.me;
    }
}

Answer 2

Here you declarate a public variable (array)

public double me[ ];

and here you instantiate it in a method

me = new me[69]

Answer 3

HeyThere obj1; double a = obj1.me[0]; This is going to give an error in Java though, because me is not instantiated

Answer 4

Yes, you certainly can! Because me is public, you can access it from outside of the class in which it is stored.
Also, you spoke of accessing it from a void method. The return type of a method has no effect on the data it can access; void only means that the method doesn't return a value when called.
