public static void main(String[] args) {
TableTennisPlayer p1=new TableTennisPlayer();
p1.setName("彭万里");
p1.setAge("23");
System.out.println(p1.getName()+","+p1.getAge());
p1.eat();
p1.study();
p1.speak();
System.out.println("-----------------------------");
basketballPlayer b1=new basketballPlayer("马宏宇","25");
System.out.println(b1.getName()+","+b1.getAge());
b1.eat();
b1.study();
