Beginner Java Summary

In the process of learning Java, the summary is as follows:

First we understand the classification of computer language programming, computer language is divided into machine language, assembly, high-level language, including the characteristics of the three languages, let me in-depth understanding of the meaning of the development process of computer language, and then we learned the algorithm, how to describe the algorithm how to make the algorithm flowchart , so it's good to exercise the logical thinking ability of our brains and understand how the computer works. Java is a versatile, high-level language. It can develop small programs on Web pages, applications running on the desktop, server-side middleware for clients and servers, and for Web servers, embedded systems, and smart devices, then learn how virtual machines work, understand the concepts of class libraries, and Java's operating environment. Where the JDK is called the Java Development toolset. This includes the Java compilation environment, the runtime environment, the debug environment, and the underlying library, which is called the Java Runtime environment. Includes virtual machines, core class libraries, and connection files, and the JDK contains the JRE. To understand these basic concepts and theories next is to understand Java's first program Hello World, which said in the beginning as a small white I can hardly understand the true meaning, but when you step-by-step, to debug the environment variables, In accordance with the teacher handed into their own mind to think again to understand the profound meaning of the enlightened after the feeling is also very good, this thing let me summarize to have patience, and analysis of the importance of the problem, so far this time the summary is here.
