泛型自定义对象的equlas怎么写？求高手！...怎么写都运行equals方法。。郁闷

￣□￣｜｜....equals不能写泛型.....后面有讲到了{:soso_e101:}

你应该是想运行你的equals方法吧。把 public boolean equals(P p1)改为
public boolean equals(Object obj)  {
    if(!(obj instanceof People))
    return false;
   People p1 = (People)obj;
   System.out.println(this.name+".....equals"+p1.name);
   return this.name.equals(p1.name)&&this.age==p1.age;
  }

哥们，你搞错意思了...不过现在已经知道了:victory:
