Java SE: Inheritance, Interfaces, and Collections, Part 8 of 18

Course description

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) with a focus on many of the common programming Java commands like Arrays, and Inheritance. The course will conclude with Exceptions, Polymorphism, Collections, Generics and other useful Java classes.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course is intended for programmers who are interested in adding Java to their skills. The students should be familiar with object-oriented principals and the concept of object-oriented programming.
