can i use getters and setters to already initialized variable?

Question

Can i use getters and setters to a already initialized variable (names)? it has been initialized in class level as the values are used in many method.

Class Family{ private String names[] = {"Arthur","Molly","Ginny","Fred", "George","Ron"}; // Is it ok to initialize this way since the names will be used in many methods. private String surname; public void displayOccupation(){ for(int o=0; o<occupation.length; o++){ System.out.println(names[o]+ "\t"+ occupation[o]+"\n"); } } public void displayNames(){ setSurname("Gates"); for(int x=0; x<names.length; x++){ System.out.println("\n"+rel[x]+"\t"+" = "+names[x]+" "+surname); } } public String getSurname(){ return surname; } public void setSurname(String s){ surname=s; } }

Or do i have to re initialize it in every method that access the private variable ?

Yes. In fact, that's most of the point of setters and getters. — nhgrif

“re-initialize it in every method” makes no sense at all. Why would you ever want to have a variable if you overwrite it before any access? — Holger
