You need to instantiate the xyz.java class in your main_activity.java like :

xyz xyzInstance = new xyz();

You can then access the public methods and attributes of xyz class using 

int x = xyzInstance.value;

You can also make the values inside xyz class static and directly access the values like :

int x = xyz.value;

first of all you need to create Xyz.java class object like this:

Main_Activity.java

Xyz x=new Xyz();

//use x object to get values from xyz class

int value=x.mydata;

Xyz.java

class Xyz

{

public int mydata=10;
