Chapter 1
Basic Java Syntax
Java is one of the most versatile of all the computer programming languages and one of the easiest to learn. In this chapter, we will be covering the basic syntax of the language, which is the first thing you must learn:
Whitespace
Whitespace characters are what makes the java code much easier to read and consist of spaces, newlines, and tabs. Usually, a whitespace character will be ignored by the Java compiler so, even if you were to use large amounts of it in your code, the actual bytecode that is generated would be quite small and would have an impact on system memory.

Do be careful of excessive use, though, because it can make the code hard to read.

Styles
Styles is all about how the source code is formatted. A Java file is normally formatted so that it is easy to read and that is where style guidelines come into play. These are standards that are usually set by an individual or an organization; this formatting is ignored by the Java compiler and it includes the use of indentation, newlines, and spacing. You can also use comments to format the code and add in notes so that anyone else reading your code can see what is going on. Styles must deal with the formatting of the source codes.

Generally, we format a Java file so that it becomes easier to read. To format a Java file, we need to look at style guidelines. Style guidelines are mainly standards followed by company, organization or individual. Generally, when setting guidelines developers keep in mind formatting of code which is easier to read. This formatting is ignored by the compiler. Styles include the use of indentation, spacing, and newlines which format source codes as per developers.

Comments are used to format code and add notes so that any other programmer reading the code gets the idea behind the code.
Example 1 Bad Formatting // Bad Style Coding // Not easy to read, no indents usedpublic class Welcome {public static void main(String[] args){int i = 0; // single line commentfor(int i=0;i<=10;i++){int j = 1;int k = j;System.out.println("Welcome to comments");}} Example 2 Good Formatting // Good Style Coding // Very easy to read, excellent use of indentspublic class Welcome {public static void main(String[] args){int i = 0; // single line commentfor(int i=0;i<=10;i++){int j = 1;int k = j;System.out.println("Welcome to comments");}}}

Comments
Comments are very important because they allow you to add notes to your source code, thus making what could be a complicated piece of code much easier to read and to debug. They are not read by the Java compiler so they will have no impact on memory. There are a couple of types of comments: Single line begins with a // and anything written between // and the end of the line is ignored Multi-line begins with /* and ends with */ - anything written in between is ignored and this can cover many lines of your code. public class Welcome { public static void main(String[] args){int i = 0; // this is a single line commentfor(int i=0;i<=10;i++){/* int j = 1;int k = j;System.out.println("Welcome to comments"); *//* multi-line comment, whole code in between will be commented out */}}}
Identifiers
Identifiers are the collective names that are given to methods, classes and variables in Java. There are rules about the naming conventions for identifiers and these follow: Identifiers must start with a Unicode character, underscore or dollar sign Numbers can be included after the first character, along with dollar signs, underscores and Unicode characters Try to avoid using currency symbols, like $ if you can Identifier names are case sensitive You cannot use a reserved keyword Use capital letters to separate two or more words in the name Valid Identifiers Invalid Identifiers Comments tree Tree case-sensitive my2var 2myVar digit as the first character myNewVar my@new@var invalid character - @ switching switch a reserved keyword
Reserved Keywords
There are several words in Java that are reserved for use by the language and you cannot use them for anything other than their intended purpose, especially not for naming. The reserved keywords are: abstract assert boolean break byte case catch char class const continue default do double else enum extends final finally float for goto if implements import instanceof int interface long native new package private protected public return short static strictfp super switch synchronized this throw throws transient try void volatile while
