Test the derived constructor, base constructor and initialization block calling sequence

BaseConstructor.java

class BaseConstructor
{
	static class Base
	{
		{
			System.out.println("Base initialize block");
		}
		Base() 
		{
			System.out.println("Base()");
		}
	}
	
	static class Derived extends Base
	{
		{
			System.out.println("Derived initialize block");
		}
		Derived()
		{
			System.out.println("Derived()");
		}
	}
	
	public static void main(String[] args)
	{
		Base b = new Derived();
	}
}
