Being familiar with a framework is actually an optional knowledge for becoming a JAVA programmer.

Frameworks will have a lot of reusable code, good hierarchical relationships and business control logic. Framework-based development allows you to save a lot of development costs. Currently popular frameworks include Struts and Spring.
