Basic concept of Getters&Setters

public class Main {
    public static void main(String[] args){
        getter_setter obj1 = new getter_setter();
        getter_setter obj2 = new getter_setter();

        obj1.setValue(9);
        obj2.setValue(11);
        System.out.println(obj1.getValue());
        System.out.println(obj2.getValue());
    }
}
