Java is a very popular programming language and is used in many enterprise applications. It runs on 3 billion devices worldwide, and it’s used by more than 12 million developers. Java is an object-oriented programming language and has rich set of Built-in APIs. Java is simple and easy to learn when compared to many other programming languages.

This Kaliyona tutorial covers all the important topics of “Core Java” including a brief introduction to the programming language, installation, object-oriented concepts, Collections etc. This course also includes lots of hands-on programs and coding challenges to enhance the learning and the student will be awarded with a Course Completion certificate at the end.

Contents of the Course (Currently 8 modules have been released) :

1. Introduction: A brief introduction of Java programming language, its origin and how the Java platform works. Also covers Installation, the first program that user will be writing “Hello World” and its execution in command prompt and IntelliJ IDE
