studentregist.java

有一个接口,用抽象类实现它的部分功能,再用实现类继承抽象类,实现其它没实现的接口方法

package cn.edu.test;
import cn.edu.csu.Student;
//import cn.edu.csu.*;

public class StudentRegist{
  public static void main(String[] args){
    Student stu = new Student("draglong",30,"Male",16);
    Student stu1 = new Student("draglong",30,"Male",16);
	System.out.println(stu.hashCode());
	System.out.println(stu1.hashCode());
	stu.setName("chenlong");
	
    System.out.println("stu对象的信息如下：姓名: " + stu.getName()  + " 年龄: " + stu.getAge() + " 性别: " + stu.getSex() + " 年级: " + stu.getGrade());
    System.out.println("stu1对象的信息如下：姓名: " + stu1.getName()  + " 年龄: " + stu1.getAge() + " 性别: " + stu1.getSex() + " 年级: " + stu1.getGrade());
//    Student stu2 = new Student();

    Student stu2 = new Student();
//	stu2.stu_name = "liujing";
//	stu2.stu_age = 888888;
	stu2.setAge(88888);
	System.out.println(stu2.getAge());
  }
