Java Programming Level 1: Introduction for Programmers Course Outline
Overview
In this live, instructor-led training course, students who already have a programming background will learn to program in Java, including:
• How Java works and its place in the world of programming languages
• Work with and manipulate strings
• Perform math operations
• Work with Java operators and loops
• Gain a deeper understanding of Object Oriented Programming concepts
• Make best use of the Java collections framework
• Best practices for dealing with exceptions
• Package Java code
• Work with external data storage systems.
This Java course is taught using Java 12.
Audience
Students new to the Java language who already have experience with other programming languages.
Prerequisites
This course is specially designed for those with prior programming background. You should also have a working knowledge of Object Oriented Programming concepts. If you do not have prior programming experience nor are not familiar with Object Oriented Programming, you should instead attend our Java Programming Level 1: Introduction for Non-Programmers" course. To view the course outline for the alternative course for non-programmers see:
