JAVA Programming Fundamentals

Audience:

Programmers moving to object-oriented programming using JAVA

Prerequisites:

Professional programming experience in a high level language, such as COBOL and Visual Basic.

DESCRIPTION

This course is paced to provide a solid foundation in Java™ for programmers without syntax experience in a C-based language. Intensive and hands-on, the course emphasizes becoming productive quickly as a Java programmer. Besides learning the basic structure and syntax of the language, students will also learn object-oriented principles and how they are applied in Java applications. The course then covers several of the provided API packages, such as I/O streams, collections, and accessing a database with JDBC. This course is current to Java 7 and uses the Eclipse IDE.
