Programming Tutorials

Excellent Free Tutorials to Learn Java

Java is a general-purpose, concurrent, class-based, object-oriented, high-level programming language and computing platform first released by Sun Microsystems in 1995. It’s related in some ways to C and C++, in particular with regard to its syntax, and borrows a few ideas from other languages. Java applications are compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.

Java is designed to be simple enough that many programmers can quickly become proficient in the language. It’s one of the most popular programming languages especially for client-server web applications.

Some popularity indexes show that Java holds the top spot with C. The respected TIOBE Index shows Java remains the most popular programming language.

Here’s our recommended tutorials to learn Java. If you’re looking for free Java programming books, check here.

1. Introduction to Computer Science using Java by Bradley Kjell, Central Connecticut State University

Introduction to Computer Science using Java is a first course in Computer Science using the programming language Java. It’s intended for high school AP Computer Science classes, for university level CS-I classes, and for self study.

There are about 20 pages per chapter. If you spend about 3 minutes per page each chapter will take about 60 minutes, or longer if you copy and run some of the programs.

6. Google Java Style Guide by Google

This document serves as the complete definition of Google’s coding standards for source code in the Java Programming Language. A Java source file is described as being in Google Style if and only if it adheres to the rules herein.

Like other programming style guides, the issues covered span not only aesthetic issues of formatting, but other types of conventions or coding standards as well. However, this document focuses primarily on the hard-and-fast rules that we follow universally, and avoids giving advice that isn’t clearly enforceable (whether by human or tool).
