Other Ways of Singleton in Java [duplicate]

Answer 1

Here is how I do it. It is faster, because it only requires a synchronized block when the instance is created.

public class MyClass
{
    private static MyClass INSTANCE=null;

    private MyClass()
    {
    }

    public static MyClass getInstance()
    {
        if(INSTANCE==null)
        {
            synchronized(MyClass.class)
            {
                if(INSATCNE==null) INSTANCE=new MyClass();
            }
        }
        return INSTANCE;
    }
}
