This study guide covers objects and classes in Java. Key concepts include: defining objects and classes, understanding objects as instances of classes, using the new keyword and constructors for object instantiation, accessing instance variables with the dot operator (.), and the difference between classes (blueprints) and objects (instances). It also touches upon how these concepts connect to arrays, ArrayLists, and inheritance. The guide provides a real-world example using the Student class and includes practice questions.
