Java Basics
This chapter explains the basic syntaxes of the Java programming language. I shall assume that you have written some simple Java programs. Otherwise, read "Introduction To Java Programming for First-time Programmers".
To be proficient in a programming language, you need to master two things:
The syntax of the programming language: Not too difficult to learn a small set of keywords and syntaxes. For examples, JDK 1.8 has 48 keywords; C11 has 44, and C++11 has 73.
The Application Program Interface (API) libraries associated with the language: You don’t want to write everything from scratch yourself. Instead, you can re-use the available code in the library. Learning library could be difficult as it is really huge, evolving and could take on its own life as another programming language.
The first few sections are a bit boring, as I have to explain the basic concepts with some details.

1. Basic Syntaxes
1.1 Steps in Writing a Java Program
The steps in writing a Java program is illustrated as follows:

Step 1: Write the source code Xxx.java using a programming text editor (such as Sublime Text, Atom, Notepad++, Textpad, gEdit) or an IDE(such as Eclipse or NetBeans).
Step 2: Compile the source code Xxx.java into Java portable bytecode Xxx.class using the JDK Compiler by issuing command:
javac Xxx.java
Step 3: Run the compiled bytecode Xxx.class with the input to produce the desired output, using the Java Runtime by issuing command:
