Exception Handling in Java

Why do we use "new" keyword while throwing exception. Like for e.g. throw new IllegalArgumentException. Why did we use new there.

Hi Pranjal Agnihotri !

Because it is a class, so you are creating a new instance of the IllegalArgumentException class.

If you are really interested you can take a look at the source code since everything is open.

Does that make sense?

Thank you sir , Now I understood that's why you were using getMessage() which is a method of that IllegalArgumentException class.
