Get string from one class to another class in Android? -

i need string variable 1 class of project class,

in first class, made string type variable , global, this: name of class firstclass

 public string  firstclassvar; 

and assigning value in method

public string requestforserverdata(string strurl) throws ioexception, unknownhostexception, illegalargumentexception, exception { //additional code   firstclassvar   = myobject.getstring("values"); //additional code } 

now in second class, doing this:

  public firstclass getvar;    public void method{       string secondclassvar;              secondclassvar=getvar.firstclassvar;  } 

by doing crashes. have done thing in firstclass is

public string getstringpublically() {        return firstclassvar;     } 

and accessing class doing this

   secondclassvar =getvar.getstringpublically(); 

and doing crashes app.

now bit new android, , don't know basic way access string class.

you can use sharedpreferences set/get values in class want. here topic it
