Use of Class<...> in Java

Question

I have come across many java programs where I have found a style of programming new to me:

Class_name<...>

Can anyone plase explain what is this.?

It seems that you are asking about [generics](http://docs.oracle.com/javase/tutorial/java/generics/types.html) — Pshemo, Apr 06 '13 at 18:14

Angular backets are used to specify generics.

Check this post: Why is Java's Class<T> generic?

This feature has been added in jdk 5 onwards and purpose is type safety to avoid class cast exception – spandey Jan 10 '18 at 06:17

http://docs.oracle.com/javase/tutorial/java/generics/ will help. generic type is in short saying a param of type Object will in fact be using specified class or interface instead. so you can have an array list with just strings. why - type safety (less bugs that are difficult to spot) and easier to type.
