关于继承（一）

public class A
{
	public A()
	{
		System.out.println("A constructor");
	}
	
	{
		System.out.println("A block");
	}
	
	static
	{
		System.out.println("A static block");
	}
}

 

public class B extends A
{
	public B()
	{
		System.out.println("B constructor");
	}
	
	{
		System.out.println("B block");
	}
	
	static
	{
		System.out.println("B static block");
	}
}

 

public class TestMain
{
	/**
	 * @param args
	 */
	public static void main(String[] args)
	{
		B b = new B();
	}
}

 

输出结果：

A static block
B static block
A block
A constructor
B block
B constructor
