Is it bad practice to have my getter method change the stored value?

Question

Is it bad practice to change my getter method like version 2 in my class.

Version 1:

 public String getMyValue(){
     return this.myValue
 }
         


        

Answer 1

I do feel this is a bad practice unless and until you explain the reason why it is so necessary for you modify the object inside the getter method instead of doing it inside the setter method.
Do you feel this cannot be done for some reason? Could you please elaborate?
