Course Overview

This course is designed for programmers and developers who are new to the Java language. It provides a solid foundation for writing Java, the latest programming language to be integrated into the Oracle Database. The course covers the fundamental concepts needed to write Java programs effectively. Students will learn the basics of object-oriented programming, such as inheritance, how an object is structured and how an object is instantiated, as well as flow control, data types, error handling, performance tips and an introduction to some of the common Java packages. The course concludes with a brief discussion on JDeveloper and how this IDE tool can assist in developing Java code. Numerous hands-on exercises solidify the concepts discussed in class and the course's step-by-step approach makes it accessible to those without any object-oriented experience. Concepts taught provide the necessary foundation for students to proceed to more advanced Java topics.
