Java 1.8 Core

The main goal of the training is to apply the basic Java Concepts to software design and development. This course promotes Object-Oriented Programming (OOP) using Java 1.8 SDK core concepts which include the basic Java Application Programming Interfaces (APIs), the OOP principles, Java data structures, inner classes, concurrency, and streamed file transactions using new IO. The outline also covers the memory management and Java administration concepts for software performance. It also includes all new features of Java 1.8.
