Learning to Program with Java

All HOTT courses are available face-to-face, remote-live, on-demand or on-site at your facility. 

This hands on Java Programming course provides an introduction to programming using the Java language. Students are introduced to the application development cycle, structure of programs, and specific language syntax. The course introduces important algorithmic constructs, string and character manipulation, dynamic memory allocation, standard I/O, and fundamental object-oriented programming concepts. 

The course explains the use of inheritance and polymorphism early on so the students can practice extensively in the hands on labs. Structured programming techniques and error handling are emphasized. The course includes the processing of command line arguments and environment variables so students will be able to write flexible, user-friendly programs. Comprehensive hands on exercises are integrated throughout to reinforce learning and develop real competency.

Students Will Learn:

• Fundamental Elements of Programming
• Classes, Objects and Methods
• Structured Programming Techniques
• Arrays and Data Structures
• Exception Handling
• String Handling
• Fundamental Algorithms
• GUI Programming Concepts

Course materials include student guide, hands-on lab manual and USB flash drive containing examples and lab files. Students receive a certificate of completion at the end of class.

This class is intended for non-programmers. Students who already understand fundamental structured programming and object-oriented techniques should attend the Java Programming course instead of this more introductory course.

Course Prerequisites: Familiarity with computers.

Note: Classes do not have fixed location. Prior to each class they examine the geographical location of the enrolled students and then select a venue that will provide most convenient overall access for the students. Classes are held in hotel conference rooms and exact location is determined 2 weeks prior to the course date.
