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

Use set:

yourList = new ArrayList(new LinkedHashSet(yourList));

This will create list without duplicates and the element order will be as in original list.

Just do not forget to implement hashCode() and equals() for your class Blog.
