Reviews

This course introduces the Java programming language and how to develop Java applications using Eclipse. Students learn the syntax of the Java programming language, object-oriented programming using Java, exception handling, generics, collections, and file input/output (I/O). During the course, students will develop and test Java applications using Eclipse. This course covers Java SE 11.

  • Throughout the course students will also work on a "project" which develops a complex Java application by applying principles learned to meet changing application requirements. This project is intended to simulate the programming environment they would encounter in real-world projects by providing application requirements and challenging the student to write Java code to meet those requirements.

Skills Gained

After completing this course, the student should be able to:

  • Apply OOP principles
  • Design OO applications using abstraction, encapsulation, modularity and hierarchy
  • Use Java exceptions to guarantee graceful error recovery for your application
  • Create and use inner classes in your program to make them concise and clear
  • Do input/output using Java
  • Create servlets and JavaServer Pages
  • Use Eclipse for Java application development

Who Can Benefit

This course is intended for programmers who are interested in adding Java to their skills.

Prerequisites

It is beneficial but not required for students to be familiar with object-oriented principles and the concept of object-oriented programming.
