employee.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.csu.oo.overrideoper;

public class Employee {
  String name;
  int id;
  String sex;
  
  public Employee(String name, String sex){
    this.name = name;
    this.sex = sex;
  }
  /**
   * @param name
   * @param id
   * @param sex
   */
  public Employee(String name, int id, String sex) {
    super();
    // TODO Auto-generated constructor stub
    this.name = name;
    this.id = id;
    this.sex = sex;
  }
  public int getId() {
    return id;
  }
  public void setId(int id) {
    this.id = id;
  }
  public String getName() {
    return name;
  }
  public void setName(String name) {
    this.name = name;
  }
  public String getSex() {
    return sex;
  }
  public void setSex(String sex) {
    this.sex = sex;
  }
  @Override
  public String toString() {
    // TODO Auto-generated method stub
    return  id + " , " + name + " , " + sex;
  }
  @Override
  public boolean equals(Object obj) {
    //如果要比较的obj对象为空，返回false
    if(obj == null){
      return false;
    }
    //如果比较的是同一个对象，返回true
    if(this == obj){
      return true;
    }
    //判断比较的对象的类型是否相同。不同返回false
    if(this.getClass() != obj.getClass()){
      return false;
    }
    //将Object类型的对象转换为Employee类型的
    Employee e = (Employee)obj;
    
    return new Integer(this.id).equals(new Integer(e.id)) && 
               this.name.equals(e.name) && this.sex.equals(e.sex);
  }
  
  
}
