Public class Example {

    private int number;

    public Example(int number){
        this.number = number;
    }

    public int getNumber(){
        return number;
    }

    public void setNumber(int number){
        this.number = number;
    }

    public static void main(String[] args){
        Example e = new Example(5);

What is preffered when accessing a variable within its own class; "e.number" or "e.getNumber()" ?
