在这里插入代private  String  name;
private  int age;public D() {}public D(String name, int age) {this.name = name;this.age = age;}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}
public DD() {
}public DD(String name, int age) {super(name, age);
}
public  void  a(){
D s=new D("张三",25);
D s2=new D("李四",28);System.out.println(s.getName()+"老司机"+s.getAge()+"的基础班老师正在讲JavaSE");System.out.println(s2.getName()+"老司机"+s2.getAge()+"就业班老师讲JavaEE");
}
public static void main(String[] args) {DD a=new DD();a.a();
}
