Audience

Programmers with a knowledge of Java principles who wish to gain a more in-depth understanding of Java classes

Prerequisites

Completion of the previous courses in the Java curriculum

Course Aim

To explain the structure of Java classes, outline the properties of an object and its interfaces, and explain exception handling

Learning Objectives

Describe the structure of Java classes and the function of methods, instance variables, and class variables within the class declaration. Describe the purpose of super references in a Java program. Describe the use of constructors, the finalize method, and garbage collection in Java. Discuss the use of object serialization in Java. Describe casting and reflection and the declaration, implementation, and function of interfaces within a Java object.
