这是清华大学编写的JAVA教材中所有题目的源代码！

abstract class Employee
{
	int basic=2000;
	abstract void salary();//抽象方法没有方法主体
	void display()
	{ System.out.println("员工最低薪资等于"+basic);}
}

class Manager extends Employee
{
	void salary()
	{
		System.out.println("经理薪资等于"+basic*5);
	}
}

class Worker extends Employee
{
	void salary()
	{
		System.out.println("工人薪资等于"+basic*2);
	}
}

public class AbstractDemo
{
	public static void main(String args[])
	{
		Manager m=new Manager();
		m.display();
		m.salary();
		
		Worker w=new Worker();
		m.display();
