This chapter explores various standard classes and their methods to let you discover and learn the functionality that is already been provided by the Java API itself.

The Java API has loads of utility functionality. Many times we would end up re-writing a similar kind of code instead of just re-using the available functionality because

• We are unaware of such functionality being available.
• We are not sure on exactly how to use it.

Hopefully this chapter should address this problem to a certain extent as it will discuss the available functionality class by class and method by method providing working examples along the way.
