Hi All, Thanks for stoping to help me :)

I have a question, may be for some of you, it will be a basic question :)

I have two lists ( not java lists, you can say two columns)

For example

**List 1**            **Lists 2**
  milan                 hafil
  dingo                 iga
  elpha                 binga
  hafil                 mike
  meat                  dingo
  iga                   
  neeta.peeta    

What I want ! I want that it returns me that how many elements are same. For this example it should be 3 and it should return me similar values of both list and different values too.

Should I use hashmap if yes then what method to get my result?

Please help

P.S: It is not a school assignment :) So if you just guide me it will be enough
