This is a course for programmers who has an understanding about the Java language internals but still learning the Java language. This course covers the general programming topics more in detail and includes new features like functional programming, streams and collections framework.
This course is designed to be a hands-on training with labs and practices for each lesson. Students needs to have general programming skills with Java as this course covers them in more detail. New programming features that are added in Java 8 also makes this course useful for advanced programmers who developed applications with JDK versions prior to JDK 1.8.
OUR COURSES WILL OPEN IF MIN 3 PARTICIPANTS
Who Is This Course For :
New Java Programmers who has a general understanding of the Java programming concepts and wants to cover them more in detail for to develop applications. Advanced programmers who worked JDK versions prior to JDK 1.8 and want to learn the new concepts like functional programming, lambda functions, streams and collections framework.
