典型案例,  建议自己调试代码,观看结果,分析流程!

public class TestYourCRoot {



	public static void main(String[] args) {

		// TODO Auto-generated method stub

		new c3();

	}

}



class c1{

	static 

	{

		System.out.println("c1 static 1");

	}

	{

		System.out.println("c1 codedata 4");

	}

	public c1(){

		System.out.println("c1 构造器  5");

	}

	

}



class c2 extends c1{

	static

	{

		System.out.println("c2 static 2");

	}

	{

		System.out.println("c2 codedata 6");

	}

	public c2()

	{

		System.out.println("c2 构造器 7 ");

	}

	public c2(String msg)

	{

		//super();

		this();

		System.out.println("c2 带参数的构造器  8 " + msg);

		

	}

}



class c3 extends c2{

	static{

		System.out.println("c3 static 3");

	}

	{

		System.out.println("c3 codedata 9");

	}

	public c3()

	{

		super("雇佣兵");

		System.out.println("c3 构造器  10");

	}
