An aspiring Java developer should first become familiar with the basic concepts and syntax of Java. We briefly went over the concept of object oriented programming in the previous chapter, where we learned that Java programs use software objects to model entities. To recap, software objects hold information about both the current state usually represented by the values of the object's properties, and the object behavior described by the methods that may be used to simulate specific types of actions.
