Edison Info Systems

A high-level programming language developed by Sun Microsystems. Java was originally called OAK, and was designed for handheld devices and set-top boxes. 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 similar to C++, but simplified to eliminate language features that cause common programming errors.

Java source code files (files with a .java extension) are compiled into a format called byte code (files with a .class extension), which can then be executed by a Java interpreter.

What is JAVA?

Java is Easy to learn Java is an Object Oriented

Programming Language Great collection of Open Source

libraries Powerful development tools e.g.

Eclipse , Netbeans Java is FREE Java is Platform Independent Excellent documentation support -

Javadocs

Why choose JAVA Programming Language ?

On full performance of the Java platform gives you the following features:

Development Tools: The development tools provide everything you'll need for compiling, running, monitoring, debugging, and documenting your applications. As a new developer, the main tools you'll be using are the javac compiler, the java launcher, and the javadoc documentation tool.

Deployment Technologies: The JDK software provides standard mechanisms such as the Java Web Start software and Java Plug-In software for deploying your applications to end users.

What Can Java Technology Do?

Application Programming Interface (API): The API provides the core functionality of the Java programming language. It offers a wide array of useful classes ready for use in your own applications. It spans everything from basic objects, to networking and security, to XML generation and database access, and more. The core API is very large; to get an overview of what it contains, consult the Java Platform Standard Edition 7 Documentation.

User Interface Toolkits: The JavaFX, Swing, and Java 2D toolkits make it possible to create sophisticated Graphical User Interfaces (GUIs).

Integration Libraries: Integration libraries such as the Java IDL API, JDBC API, Java Naming and Directory Interface (JNDI) API, Java RMI, and Java Remote Method Invocation over Internet Inter-ORB Protocol Technology (Java RMI-IIOP Technology) enable database access and manipulation of remote objects.

Access restrictions are enforced (public, private) Byte codes are verified, which copes with the threat of a

hostile compiler Architecture-Neutral Compiler generates bytecodes, which

have nothing to do with a particular computer architecture Easy to interpret on any machine Portable Java goes further than just being architecture-neutral Standard libraries hide system differences The Java environment itself is also portable: the portability

boundary is POSIX compliant.

What makes JAVA so Secure and Powerful?

Why Java is Secure?

1: Console Application: A Java Console application can only display textual data. Console applications resemble DOS based applications in that all interaction with the program is through keyboard and text output. The mouse, and any use of multiple windows is not supported.

Background applications are almost always written as console applications. A background application is a program that runs, often for a long period of time, without user interaction.

Types of JAVA Application?

Anti-virus programs that scan while the user is using the computer

Business Data processing/loading applications that process large volumes of data

Examples of Background Applications Include

2: Windows Application Window Applications have facilitated enterprises to

perform dynamically with easy access to information. Window Applications are based on Graphical User

Interface. Window Application can be installed on a single computer

or laptop used to Perform a specific task. There is full control over window application to protect it

from various vulnerabilities. In java, J2SE is used for developing the Window Application.

3: Web Application: Web Applications are used to create dynamic websites. Java provides support for web application through Servlets and JSPs. We can create a website with static HTML pages but when we want information to be dynamic, we need web application.

Types of JAVA Application?

4: Mobile Application: Java ME has become popular in mobile devices, where it competes with Symbian, BREW, and the .NET Compact Framework.

The diversity of mobile phone manufacturers has led to a need for new unified standards so programs can run on phones from different suppliers - MIDP. The first standard was MIDP 1, which assumed a small screen size, no access to audio, and a 32kB program limit. The more recent MIDP 2 allows access to audio, and up to 64kB for the program size. With handset designs improving more rapidly than the standards, some manufacturers relax some limitations in the standards, for example, maximum program size.

Types of JAVA Application?

Google's Android operating system uses the Java language, but not its class libraries, therefore the Android platform cannot be called Java. Android executes the code on the Dalvik VM instead of the Java VM.

Types of JAVA Application?

1. Core Java & Swings Training

2. JAVA J2EE

3. JAVA Spring & Hibernate
