java string to byte arrayThe advent of open source and community development changed the way developers and programmers create new applications and collaborate on the development of new projects and designs, but there is one downside to open source, and that is that this type of collaboration can lead to a diverse approach when it comes to coding approaches and standards. That is why the Google Java Coding Standards guide has been seen by many within the industry as a great way to standardize the approach to coding in Java applications. And let’s face it, who is going to argue with Google anyway? As one of the most powerful providers, it pays to ensure your coding meets the requirements set out in the guide. If you are new to Java, the Introduction to Java Training Course offers 205 lessons and over 20 hours of video content that will teach you all you need to know about coding in Java. It will show you how to write stand-alone applications using the Java language and Eclipse IDE for development purposes. It will help you to accurately implement object oriented principles using the various Java features like classes, interfaces and references. You will create well-scoped classes using pages and you will learn to write programs that handle exceptions. The course will teach you to read and write data input using various output and input streams and you will learn to use the Java collections framework to group objects and work with those groups.

The Google Java Coding Standards Guide

Essentially the Java coding standards guide standardizes the way in which applications are coded in terms of good practices. The guide is divided into six sections, each section dealing with different Java coding topics. The sections included in the Google Java Style guide are:

1.       Source file basics

2.       Source file structures

3.       Formatting

4.       Naming

5.       Programming practices

6.       JavaDoc

Google Java Coding Standards – Source File Basics

The source file basics include standards that determine how to name a file, basic file encoding, Ascii character rules and whitespace rules. The most important style rules in terms of source file basics state that source files must be named using the .java extension. The name itself must contain the name of the top level class it contains. Source file names are also case sensitive and that should be kept in mind when naming source files. The only whitespace character that should appear anywhere in the file should be the Ascii horizontal space character. This means that whitespaces in characters in strings and literals are all escaped, and that tab characters should not be used for indentation purposes.

To learn how to code in Java, enroll in the Java 101: Java Programming for Beginners course now. This course will teach you how to set up the Java development environment and how to troubleshoot any Java errors you may have. It will teach you how to work with the various variables within Java. The course will show you how Java strings work and how to use them in your applications. You will learn to work with simple and complex Java conditionals and the course will show you how to use the switch case break statement, how to use the while and do while loop and how to create the Java for loop. You will work with arrays and create simple and complex Java functions. The course will introduce you to the concept of Java inheritance and it will show you how to implement inheritance in your applications. The course also includes lessons on working with XML and XML data.

Google Java Coding Standards – Source File Structures

According to the Google Java coding standard, each source file may consist of license or copyright information, a package statement, import statements and then exactly one top level class, in that particular order. Developers will use one blank line only to separate each section within the file. This section also specifies that no wildcard imports are allowed. Import statements should not be line wrapped and the column limit of 80 or 100 does not apply to these statements. This section also sets out the standards for grouping and sorting import statements.

Programming Java for Beginners – The Ultimate Java Tutorial will take you from zero Java programming skills to a certified Java programmer. This course offers 115 lectures and 10 hours of video content that will teach you all the Java skills required to program effectively in Java. It will teach you about programming using object-oriented concepts like classes, objects, loops, and more. The course is suitable for beginners and is aimed at those who thrive on learning by video and example. The training methods help you to learn by doing, therefor increasing retention and accelerating the learning process. Each step is broken down into simple to follow steps that will teach you to develop a Java program from start to finish.

Google Java Coding Standards – Formatting in Java

In terms of the google Java coding standards, programmers need to add braces where braces are optional. Braces should therefore be used with all if, else, for, while and do statements even when these structures contain only one statement. The brace should appear on the same line as the statement, so no line breaks should appear between the statement and the bracket. There should be a line break after the bracket and after the closing bracket. Block indentation should be set at two spaces. Statements should be confined to a new line per statement. Columns widths should be confined to 80 to 100 characters except for long URL or import statements.

Vertical line breaks or whitespaces should be limited to members of a class, to create logical groupings of statements. Multiple line breaks are discouraged. Horizontal whitespaces should be used to separate reserved words, separate reserved words from braces, before curly braces, on both sides of a binary operator, after closing parenthesis, between a type and variable declaration. Interior whitespaces should be avoided.

Google Java Standards

There are a number of different Java coding standards. The above is an introduction to those standards. It is important to apply the standards to your programs if you want to run them via Google in any form. These standards are not only necessary for programs running on Google, but they actually form part of best programming practices for Java in general, so learning programming standards will ultimately make you a better programmer.

To learn more about Java and how to become a Java developer, enroll in the Java – Java Programming for Beginners course. This course will teach you the basic Java concepts you need to understand to build fully functional Java programs. You will learn how Java is the base for all object-oriented programming languages and how you can improve your programming skills in any other language by learning Java. The course will teach you the basics of Java syntax. You will learn the complexities of object-oriented programming and what object-orientation means. The course will teach you about Java SE and it will take you step by step through the process of creating a Java program with user interfaces that run on Mac, PC and Linux machines. You will learn about the different variables in Java and how you can use them in your programs. Each chapter of the course ends with specially designed exercises to ensure that you can harness the power of what you have learned to create Java programs that you can be proud of.
