Question

At present I have a class that is calling the static method of a different class. What I am trying to do however is have the static method change a variable of the calling class, is that possible?

Example code:

public class exClass {
    private int aVariable;

    public exClass() {
        othClass.aMethod();
    }
}

public class othClass {

    static void aMethod() {
        // stuff happens, preferably stuff that
        // allows me to change exClass.aVariable
    }
}​

So what I would like to know is, if there is a way to access aVariable of the instance of exClass that is calling othClass. Other than using a return statement, obviously.

Answer 1

You can pass this as a parameter to the second function.

public class exClass {
   public int aVariable;

   public exClass()
   {
      othClass.aMethod(this);
   }
}

public class othClass{

   static void aMethod(exClass x)
   {
      x.aVariable = 0; //or call a setter if you want to keep the member private
   }
}
