How to remove duplicate objects in a List without equals/hashcode?

Question

I have to remove duplicated objects in a List. It is a List from the object Blog that looks like this:

public class Blog {
    private String title;
    priv         


        

Answer 1

This can be logically solved using a property. Here I have a property called a key.

1. Take out any String property in the object and put it in the list.
2. Check in the list weather that property contains if so then remove it.
3. Return the object list.
