Answer Posted / jinxuan
public class SingletonTest
{
public static void main(String[] args)
{
Singleton singleton = Singleton.getInstance();
Singleton singleton1 = Singleton.getInstance();
System.out.println(singleton == singleton1);
}
}
class Singleton
{
private static Singleton singleton = new Singleton();
private Singleton()
{
}
public static Singleton getInstance()
{
return singleton;
}
}
it means whenerver you new a Object,it returns the same
object address, i'ts Singleton Pattern. so your object is
immutable class
