Through the initial study and online information query know that the Java language is a multi-purpose language, concurrent language, class-based, object-oriented language. Java is a multi-functional high-level language, the Java language was first known as Oak, its author is James Gosling.ed Frank, Patrick Naughton, Jonathan Payne, Chris Warth added a number of features to the Java language for the next few years, making it possible to develop small programs for Web pages (applets), applications running on the desktop, server-side middleware to communicate with client and server resources, and for Web servers, Embedded systems and smart devices, and these are just a few of Java's many features.

The goal of the Java language is to eliminate the drawbacks of other languages that affect program robustness in terms of pointer and memory relationships, making the code as clear and reasonable as possible, and using object-oriented concepts to make programming easier.

The Java language consists mainly of five elements: identifiers, keywords, literals, operators, and separators. These five kinds of elements have different grammatical meanings and constituent rules, they cooperate with each other and accomplish the semantic expression of the Java language together.

A week of learning to understand the download and configuration of the JDK, a simple grasp of the use of the Javac,java command. Through the gradual in-depth study, we will learn in detail the five elements of Java, and its use, with mathematics and other related knowledge to solve the problem of the algorithm and so on. Also through their own after-school book knowledge and online teaching methods, a more comprehensive understanding of the various Java knowledge and operations.
