woman.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 Woman extends Person {
  
  String sex;
  public Woman(String name, String sex){
    super(name);
    this.sex = sex;
  }
  public boolean equals(Object obj){
    if(obj == null){
      return false;
    }
    if(this == obj){
      return true;
    }
    if(this.getClass() != obj.getClass()){
      return false;
    }
    Woman woman = (Woman)obj;
    return this.sex.equals(woman.sex) && super.equals(obj);
  }
  
  /**
   * @param args
   */
  public static void main(String[] args) {
    Woman woman = new Woman("liujing","Female");
    Woman woman1 = new Woman("liujing","male");
    System.out.println(woman.equals(woman1));
  }

}
