JAVA 抽像类使用

package org.abstractdemo;

abstract class A{
	private String name;
	public A(String n){
		this.name = n;
	}
	public String getName(){
		return this.name;
	}
	abstract void print();
}

class B extends A{
	public B(String n){
		super(n);
		System.out.print("------------");
	}
	public void print(){
		System.out.println(super.getName());
	}
}

public class AbstractDemo01{
	public static void main(String args[]){
		B b = new B("张三");
		b.print();
	}
}
