How to set a variable equal to a class?

Question

I want set an array value equal to a variable int in another class. This seems dumb but this is just one small part of what i want to do, but i can't figure this out. 

I want to take,

anArray[1] in class 'A'
and set it equal to variable 'int x' in class 'B'

I don't want to do this by going

anArray[1] = B.x;

because the class i want to grab the variable from will change. So i want to create a variable "className" and set it equal to class.B

then i could go

anArray[1] = className.x;

and when i want to grab x from a different class, i just change className from equal to class.B to equals class.C for example, which would also hold a public static int x. 

How can something like this be done?

You have too man sentence fragments and things that are wrote wrong I can hardly understand your questions.

You have three classes in a directory.

You refer to them by creating a new object...

ClassName varname = new ClassName();

Your variables set inside the ClassName are set by the ()'s

Your class should be set up like this:

public class Main{

public static void main(String[] args){

ClassName cn = new ClassName("apples");

}


}

then your other class

public class ClassName{

private String Name;

ClassName(String name){
this.Name = name;
}

public String getName(){
return Name;
}

}

Therefore speaking with the second class you can say

String name = cn.getName();

This would return the current name when executed. It will always return the set value stored in cn. Once you change the value inside the class with... idk... changeName(); it would then return the current value of it.

to declare this variable a set value without it going changing on you... and no matter how many times you change the name inside that class... you call final with it.

SOOOO:

final String name = cn.getName();

Can't be changed nor returned a different value then it when executed.

In all cases if this was not what your looking for feel free to send me a message reguarding this.
I will happily overlook your scripts to.

Objects move via reference in Java. So... Int [][] array2Dim at x0AB191 memory in RAM int [][] array2nd is the same as x0AB191 reminiscence in RAM hence, exchange a sub-script on one Object, you see the reflection on all copies. Array.Clone() is a shallow copy additionally. You can write the loops to make a distinctive Object or serialize. Are you engaged on 9 queens?
