use of private in getter and setter

[katturv]

1.use of private variable in getter and setter method??
2. how to implement singleton class in another class??
like
public class Singleton {
// class is automatically instantiated when the
// class is loaded
private static Singleton instance = new Singleton()

// constructor is made inaccessible by declaring
// it private
private Singleton() { ... }

// Access to the single instance of the class is
// provided by a static accessor method
public static Singleton getInstance() {
// returns a reference of the private instance
return instance;
}

// rest of the class implementation
}
i have one more class...how to use singleton class inside this???
class B
{
}

Create a public getter for private variable 'instance' in A, then call that getter from B.
