Java:

What is a Programming Language? Advantage of using Java, Java Life Cycle, Download JDK, Download Eclipse, Enabling Eclipse feature.

Java Basics: Naming convention for projects, package, class, method, variables, Constructor etc. Java Comments and their type, print vs println, Use of \n, \t, \r etc, How to rename, how to save, how to run program etc. How to take screenshot.
