Hi Salim; both words usually refer to "Exception Handling" and so I would suggest you study about Exceptions which is Section 2 of the Java Certification Objectives. let me give you an example of a "handler":
The words "handle" and "handler" are not Java Keywords or Reserved words. These words are adjectives used to describe what we do with "exceptions" when they happen with the try-catch-finally code blocks. The catch block is used to "handle" (verb -meaning do something with) an exception. We say that a catch block is a "handler" (noun). Hope this helps!
