重写equal

今天有点空写了一段基础代码复习一下，随便记记：

package com.dao;

public class OverwriteEquls {
	private  long id;
	private  String name;
	
	public long getId() {
		return id;
	}
	public void setId(long id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	//重写equals方法，当id和那么相同时我们认为两个对象是相同的
	public boolean equals(Object o){
		OverwriteEquls o3 = (OverwriteEquls) o;
		boolean b=false;
		 if(this.id==o3.getId() && this.name.equals(o3.getName())){
			 b=true;
		 }
		return b;
	}
	public static void main(String[] args) {
		OverwriteEquls o1= new OverwriteEquls();
		OverwriteEquls o2 = new OverwriteEquls();
		o1.setId(12l);
		o1.setName("LIMEI");
		o2.setId(12l);
		o2.setName("LIMEI");
		System.out.println(o1==o2);
		System.out.println(o1.equals(o2));
	}
}
