两种重写equals的方法

public class User {

	private String name;
	private String code;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getCode() {
		return code;
	}
	public void setCode(String code) {
		this.code = code;
	}
	
	@Override
	public boolean equals(Object obj) {//电脑重写Object的equals方法；
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		User other = (User) obj;
		if (code == null) {
			if (other.code != null)
				return false;
		} else if (!code.equals(other.code))
			return false;
		if (name == null) {
			if (other.name != null)
				return false;
		} else if (!name.equals(other.name))
			return false;
		return true;
	}
	
	
	//自己重写Object类中的equals方法；
	/*public boolean equals(Object obj){
		
		if(obj==null){
			return false;
		}
		if(!(obj instanceof User)){
			return false;
		}
		
		User u=(User)obj;
		
		if(!(this.getName().equals(u.getName()))){
			
			return false;
		}
		if(!(this.getCode().equals(u.getCode()))){
			
			return false;
		}
		
		
		return true;
