One characteristic of Java is portability, which means that computer programs written in the Java language must run similarly on any hardware/operating-system platform. This is achieved by compiling the Java language code to an intermediate representation called Java bytecode, instead of directly to platform-specific machine code. Java bytecode instructions are analogous to machine code, but are intended to be interpreted by a virtual machine (VM) written specifically for the host hardware. End-users commonly use a Java Runtime Environment (JRE) installed on their own machine for standalone Java applications, or in a Web browser for Java applets.
Standardized libraries provide a generic way to access host-specific features such as graphics, threading, and networking.
A major benefit of using bytecode is porting. However, the overhead of interpretation means that interpreted programs almost always run more slowly than programs compiled to native executables would. Just-in-Time compilers were introduced from an early stage that compile bytecodes to machine code during runtime.

Java is a high level programming Language. It was introduced by “SUN Microsystems” in June 1995. It was officially released in November 1995. It was developed by a team under James Gosling.
Primitive Data Types.
In this lesson you will learn eight primitive data types supported by java programming language.
Array and Classes.
An array can be declared as a field in a class. To create a field as an array, you can declare it like a normal array in the body of the class.
Creating a Package.
A package is a grouping of related types providing access protection and name space management. Note that types refer to classes, interfaces, enumerations, and annotation types. Enumerations and annotation types are special kinds of classes and interfaces, respectively, so types are often referred to in this lesson simply as classes and interfaces. "
Thread method in Java.
In this lesson you will learn the most important methods on this class.
List of exception.
Exception in Java is classified on the basis of the exception handled by the java compiler.
An applet is a Java program that runs in a Web browser. An applet can be a fully functional Java application because it has the entire Java API at its disposal.
A constructor is a special method that is used to initialize a newly created object and is called just after the memory is allocated for the object.

Java is a programming language originally developed by James Gosling at Sun Microsystems (now part of Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere." Java is currently one of the most popular programming languages in use, particularly for client-server web applications.
JDBC allows multiple implementations to exist and be used by the same application. The API provides a mechanism for dynamically loading the correct Java packages and registering them with the JDBC Driver Manager. The Driver Manager is used as a connection factory for creating JDBC connections.
JSP allows Java code and certain pre-defined actions to be interleaved with static web markup content, with the resulting page being compiled and executed on the server to deliver a document. The compiled pages, as well as any dependent Java libraries, use Java bytecode rather than a native software format. Like any other Java program, they must be executed within a Java virtual machine (JVM) that integrates with the server's host operating system to provide an abstract platform-neutral environment.
Servlets can be generated automatically from Java Server Pages (JSP) by the JavaServer Pages compiler. The difference between servlets and JSP is that servlets typically embed HTML inside Java code, while JSPs embed Java code in HTML. While the direct usage of servlets to generate HTML (as shown in the example below) has become rare, the higher level MVC web framework in Java EE (JSF) still explicitly uses the servlet technology for the low level request/response handling via the FacesServlet. A somewhat older usage is to use servlets in conjunction with JSPs in a pattern called "Model 2", which is a flavor of the model–view–controller pattern.
As we all know, the development of non-trivial (more than "Hello Android") apps require some pain and effort, even for skilled Java programmers. The challenge is not simpler when developing on a small mobile phone because of the limited editing and file manipulation features. But if you have these fancy Android tablets available, you can seamlessly switch to mobile development by using the JDroidLib framework.
We now offer a management tool, called ProjectBuilder for AIDE, to configure Android projects on mobile devices to be used with the JDroidLib and JTurtleLib frameworks. By installing the ProjectBuilder app, you are able to create projects that can be edited, built and run effortlessly even on cheap Android smartphones. Moreover ProjectBuilder can unpack Java sources with additional sprite images and media resources from a ZIP archive and integrate the files automatically in your Android project. ProjectBuilder is looking automatically for those archives and dispatches the files to the Android project folder. Because AndroidManifest.xml and layout files are created accordingly, the distributed app is built locally on the smartphone in a snap. The JDroidLib library is compiled only once when the project is used the first time which may take a while on narrow-chested smartphones. The following build processes use the precompiled library and last only a few seconds, not much longer than on a full-grown desktop computer.
The JDroidLib framework is ported from JGameGrid, a widely used game developing library for Java SE. Consult www.jgamegrid.com to inform you about the design principles and examples.
Want to learn "how to program" ? Algoid is made for you !
Algoid is an educational application for Android that teaches kids, teenagers and why not their parents "how to program".
★★★ With Algoid, learn programming become simple and funny !
Do you remember the Logo programming language ? This friendly turtle / robot that introduces step by step the basics of programming.
Algoid is based on the same idea of visual feedback loop : develop - run / debug - observe turtle that draw result.
★★★ Algoid go further, it embeds a real-time DEBUGGER (the first and so far the only one on Android), a step by step execution mode and SCOPE EXPLORER (for better understanding).
Still further, hide the turtle and develop your own VIDEO GAME directly from your device.
In short, Algoid will turn your Android device into a real development station dedicated to apprenticeship and fun.
Everything you need to become a future developer, whether you are a child, teenager or adult!
The goal of Algoid is to enable everyone to "learn to program" or "learn programming".
---- Highlights ----
Algoid is an all in one app that embeds tree products :
The rich integrated development environment "IDE" :
- Syntax highlighting
- BREAKPOINTS and DEBUGGER
- STEP BY STEP execution modes
- real-time SCOPE EXPLORER
- Auto completion
- Syntax error management
- Unlimited Undo/Redo
- UI optimized for small screens
The documentation platform for self apprenticeship
- Online forum
---- What's algoid is not ? ----
Algoid is not running through SL4A, it integrates its own (homemade) formal language parser. This choice was made to facilitate the debugger, step by step and scope explorer integration.
Its language AL is not Java, but its interpreter and runtime are both written in Java.
Algoid is not a compiler but a scripting language interpreter.
Algoid is not (not yet but I am working on) a c or java ide but a dedicated one for AL.

Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. Java applications are typically compiled to bytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture.
Java is, as of 2012, one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.
The original and reference implementation Java compilers, virtual machines, and class libraries were developed by Sun from 1991 and first released in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
The Java Runtime Environment (JRE) is what you get when you download Java software. The JRE consists of the Java Virtual Machine (JVM), Java platform core classes, and supporting Java platform libraries. GK
