Price: $2695.00

Course Code: JA1012

Audience

Applications Programmers and Systems Programmers

Description

Java has been gaining in popularity for over 20 years. If you are an experienced programmer who will need to start writing and maintaining Java code, this is the course for you. You will learn to utilize the structure and syntax of the object oriented Java programming language for both general business and Internet programming applications. You will be able to code, test, and execute Java programs making use of the facilities provided by the language. You will also learn about the integrated development environment (IDE), which may be RAD or Eclipse. Previous knowledge of the COBOL programming language is expected.

Objectives

Upon successful completion of this course, the student will be able to:

Discuss the basic structure and syntax of the Java Programming Language
Create, compile, and execute Java programs
Explain benefits of Object Oriented Programming
Define and explain encapsulation, inheritance, and polymorphism
Declare and use the native data types
Describe and use expressions and operators
Code object oriented Java programs using all available control structures
Create and use classes and interfaces
Share and restrict access to class members
Effectively use arrays and references
Use String and StringBuilder class methods
Describe and use method overloading
Define and use constructors and finalizers
Increase software reusability through inheritance
Use polymorphism to facilitate Java programming efforts
Define and use interfaces
Handle and create exception conditions

Prerequisites

An understanding of object oriented programming concepts would be helpful but is not required.
