Complete Java

Description

Duration: 4 Days

Description

The Java language began modestly as a programming language to address the needs of a diverse set of consumer appliances, but has since evolved to become the most popular language and platform for building enterprise level applications.  This course teaches you the syntax and core APIs of the Java programming language while also coaching you on the conventions and practical techniques necessary to code Java professionally.  Note: this class is based on Java 8.

The class begins by describing the core syntax of the Java language while also exposing students to object-oriented programming concepts.  After establishing this essential foundation, the class then covers other crucial topics like exception handling, packaging, and when to use arrays versus collections.

Learning Objectives

• Master basic Java 8 syntax.
• Know how to write, compile and execute a Java application on a Java Virtual Machine.
• Become familiar with Javadocs and how to locate Java API within Java’s immense libraries.
• Learn Java coding conventions/standards.
• Know how the object-oriented principles of encapsulation, inheritance and polymorphism manifest in Java.
• Understand the basics operations and mechanics of the Java Virtual Machine.

Audience

This class is intended for experienced software developers looking to get a foundation in Java, however no prior knowledge of Java or Java tools is assumed.

Prerequisites

There are no prerequisites for Complete Java.  Object oriented programming experience is helpful.
