Java Tutorials - Java Example Codes and Tutorials

Java is great programming language for the development of enterprise grade applications. This programming Language is evolved from a language named Oak. Oak was developed in the early nineties at Sun Microsystems as a platform-independent language aimed at allowing entertainment appliances such as video game consoles and VCRs to communicate . Oak was first slated to appear in television set-top boxes designed to provide video-on-demand services. Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web.

Java is an object-oriented language, and this is very similar to C++. Java Programming Language is simplified to eliminate language features that cause common programming errors. Java source code files are compiled into a format called bytecode, which can then be executed by a Java interpreter.

Detailed Java Course Material

Section I - Introduction to Java This section introduces you the Java programming language. These days Java programming language is being used for programming web applications. It is also widely used for mobile and electronic items.

What is Java?
Java is a high-level object-oriented programming language developed by the Sun Microsystems. Though it is associated with the World Wide Web but it is older than the origin of Web.
Java as an Internet Language
Java is an object oriented language and a very simple language. Because it has no space for complexities. At the initial stages of its development it was called as OAK. OAK was designed for handling set up boxes and devices.
Java as general purpose language
Java is an Object oriented application programming language developed by Sun Microsystems.

Java Features
Case sensitivity
What is case sensitivity: Case sensitivity is the mechanism in which words can be differ in meaning based on different use of uppercase and lowercase letters.
Java is Simple and platform Independent
The concept of Write-once-run-anywhere (known as the Platform independent) is one of the important key feature of java language that makes java as the most powerful language.
Java Enabled browsers
Java language is the most powerful language and is widely used in the web application. Today most of the web browser are java compatible.

Java Tools
Java Compiler
To commence with Java programming, we must know the significance of Java Compiler.
Java Interpreter
We can run Java on most platforms provided a platform must has a Java interpreter.
Java Debugger
Java debugger helps in finding and the fixing of bugs in Java language programs.
Java Header File GeneratorIn Java programming we need to implement some native methods. To implement these methods Javah generates C header and source files that are used by C programs to reference an Object's instance variables from native source code.
JavaDoc
This tool is used to generate API documentation into HTML format from Java source code.
Applet ViewerApplet viewer is a command line program to run Java applets.

Section II- Java Language

Java Comments
To comprehend any programming language, there are several kind of comments which are used.
Java Keywords
There are few keywords in Java programming language. Remember, we cannot use these keywords as identifiers in the program. The keywords "const" and "goto" are reserved though, they are not being currently used.
Java Data Types
Java programming language is a language in which all the variables must be declared first and then to be used i.e. to specify the name and the type of the variable. This specifies that Java is a strongly-typed programming language
Literals
By literal we mean any number, text, or other information that represents a value. This means what you type is what you get. We will use literals in addition to variables in Java statement. While writing a source code as a character sequence, we can specify any value as a literal such as an integer.
Arrays
In this section you will be introduced to the concept of Arrays in Java Programming language. You will learn how the Array class in java helps the programmer to organize the same type of data into easily manageable format.
Operators
Operators are symbols that performs some operations on one or more then one operands. Once we declare and initialize variables, we can use operators to perform certain tasks like addition, subtraction etc.
Controlling your program
We all know that the execution of the statements in a program takes place from top to bottom. We will learn how the different kinds of statement have different effects in looping like decision-making statements (if-then, if-then-else, switch), the looping statements (for, while, do-while), and the branching statements (break, continue, return) in Java programming language.
Java Classes
In this section you will be introduced to some essential classes in Java like Exceptions, Basic I/O, Concurrency etc.
Class Inheritance
To know the concept of inheritance clearly you must have the idea of class and its features like methods, data members, access controls, constructors, keywords this, super etc.
Summary
You have been introduced to the contents of Java language providing a great amount of information. Perhaps it would be a bit arduous to grasp the whole lot of things at one go. However, the implementation of these little basics will make you a substantial programmer.
