Special Singleton
I'm looking for a way to have 2 different getInstance() methods for a singleton class. The 2 methods should return 2 identical instances of that object, except a single method which should act in 2 different ways.
For example I have class MyObject, which has a getName() method. When you get an instance of the class using MyObject.getInstance(), it returns an instance whose getName() will return MyObject.name property. Instead when you use MyObject.getInstance(number), a call to getName() of the former instance will return id + name.
Thanks.

Singleton is a singleton because its getInstance() always returns a ref to the same instance, so you need another type of object. At the same time you need a class variable to keep an index which depends of getInstance parameter thus you'll have different objects. You can try following idea, it could partly help you.
class MyClass{
private static List<MyClass> listOfInstances = new ArrayList<MyClass>();
private MyClass(){
}
public static MyClass getInstance(int index){
// Check if the instance with such index already exists in the list
// otherwise create a new instance and put it into list to the certain place
// then returns it
}
public String getName(){
// find index of the instance inthe list and return it + Name
}
}
Cheers.
