Keywords

Many Java statements contain Java keywords (also called reserved words). Keywords are words that have been reserved by the developers of the Java language to have special meaning.

In terms of the number of keywords, Java is a small language.

In addition to keywords, Java statements are composed of things such as method names, class names, literals (like 5, and 4.5 and "hello").

Also Java has many libraries of pre-written classes. The learning of these library classes is a large task. You will be introduced to many important library classes in the course of the module.
