Related to Collection class

[padmaratna kamble]

we use following ways to create a collection object.
1.List l1=new ArrayList();
2.ArrayList al=new ArrayList();
3.Collection c=new ArrayList();
Why we use the first one more often but not the remaining two?

Hi,

Welcome to JavaRanch!

This is a Java question, but you've posted it in our HTML and JavaScript forum -- so it's off-topic here. I'm going to move this over to our Java in General(Beginner) forum, where someone will answer it for you.
