    Default How to make an array a global static variable

    I have an issue where I need an array as a global variable. If someone could tell me if that is possible and/or how to do that then that would be great. (insert meme here XD).

    There is no such thing as a global variable in Java.

    The closest parallel is to create a public static member of a class, then every class which wants to use that "global" would reference it from the given class.

    public class MyGlobals
    {
        public static int[] data = new int[]{1,2,3};
    }

    An alternative is to employ the singleton idiom.

    If you explain WHAT you're trying to do - a code example would be great - someone here can explain HOW to do it. The solution won't include the approach you've suggested.

    you make a global type array just as like you instantiate a array. But one thing remind it, that array elements are always get a default value irrespective of the position of a array.

    Thank you all for the help! Especially Rahul Bansal and helloworld922. My professor called the example helloworld922 gave, global variables. Sorry for the misuse of the term.
