Get string from one class to another class in Android?

Question

I need to get the string variable from one class of my project to another class,

in First class, I made a string type variable and that is Global, like this: the name of class is firstclass

 public String  firstClassVar;

and I am assigning the value to it in this method

public String requestForServerData(String strURL) throws IOException, UnknownHostException, IllegalArgumentException, Exception {
//additional code 
 firstClassVar   = myObject.getString("values");
//additional code
}

Now in second class, I am doing something like this:

  public firstclass getVar;

  public void method{
      String secondClassVar;
             secondClassVar=getVar.firstClassVar;
 }

By doing this it crashes. I have done another thing in firstclass that is

public String getStringPublically() {
       return firstClassVar;
    }

and for accessing it another class I am doing like this

   secondClassVar =getVar.getStringPublically();

and by doing this it also crashes the app.

Now I am bit new to Android, and don't know the basic way to access the string from another class.

You can use SharedPreferences to set/get values in any class you want. Here is a good topic about it
