Introduction to Java Programming

Java Introduction for Beginners

Java Introduction: Java is a high-level programming language designed by James Gosling in the year 1991. Java (1.0) was released in 1995. Oracle Corporation acquired Java from Sun Microsystems in 2010.

Brief History of Java Programming Language

History of Java: It is a general-purpose, high-level, pure object-oriented programming language. java's first name oak next goes to Green and finally becomes JAVA. Java introduction Java is the name of Coffee Seed. it is developed by James Gosling and Sun Microsystem in 1995.

James Gosling and his team started to work on java for a client's set-top box project in 1991. The first version of java (java 1.0) is released in 1995.

It is a programming language created in 1991. James Gosling, Mike Sheridan, and Patrick Naughton, a team of Sun microsystems known as the Green team initiated the Java language in 1991. Sun Microsystems released its first public implementation in 1996 as Java 1.0.

Where java programming is used?

Following are some other uses of Java :

More than 3 billion devices run the Java language 

1. Developing Desktop Applications

2. Web Applications like Linkedin.com, Snapdeal.com, etc

3. Mobile Operating systems like Android

4. Embedded Systems

5. Robotics and games etc.

6. Java is officially supported

7. Android Studio[IDE for developing Android Applications.

Features of java programming Language

Object-Oriented: In Java, everything is an Object. Java can be easily extended since it is based on the Object model.

Platform Independent: Unlike many other programming languages including C and C++, when Java is compiled. it is not compiled into platform-specific machines, but rather into platform-independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it runs on.

Simple: Java is designed to be easy to learn. If you understand the basic concept of OOP Java, it will be easy to master.

Secure: With Java's secure feature it enables to development of virus-free, tamper-free systems. Authentication techniques are based on public-key encryption.

Architecture-neutral: Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many processors, with the presence of a Java runtime system.

Portable: Being architecture-neutral and having no implementation-dependent aspects of the specification makes Java portable. The compiler in Java is written in ANSI C with a clean portability boundary, which is a POSIX subset.

Robust: Java makes an effort to eliminate error-prone situations by emphasizing mainly compile-time error checking and runtime checking.

Multithreaded: With Java's multithreaded feature it is possible to write programs that can perform many tasks simultaneously. This design feature allows developers to construct interactive applications that can run smoothly.

Interpreted: Java byte code is translated on the fly to native machine instructions and is not stored anywhere. The development process is more rapid and analytical since the linking is an incremental and lightweight process.

High Performance: With the use of Just-In-Time compilers, Java enables high performance.

Distributed: Java is designed for the distributed environment of the internet.

Dynamic: Java is considered to be more dynamic than C or C++ since it is designed to adapt to an evolving environment. Java programs can carry an extensive amount of run-time information that can be used to verify and resolve accesses to objects on run-time.

Application of Java Programming Language

1. Window Application

2. Web Application

3. Android Application

4. Mobile Application

5. Embedded System

6. Scientific Application MATLAB

7. Games Developed

8. Database Connectivity

Why learn java programming language

Beginner Friendliness: Generally, Java was designed to be relatively beginner-friendly in that it assumes the programmer is not that smart or careful, so programmers will be less likely to shoot themselves in the foot when coding Java apps.

Relatively Simple to Use: Java is a high-level language, which means Java abstracts away (i.e. handles for you) most of the complex details of the machine (computer) such as memory management, etc. Thus, you can focus on programming instead of worrying about the little details many consider both tedious and challenging.

Less Rewarding from the Start: Java is very stubborn and verbose, which means you need to write a lot of code trying to convince the language to build some features. Thus, you may need to spend a lot of time coding before you can get a working app. This may be demotivating for coding beginners.

Scalability: Easier to Maintain: Java is a statically-typed language, which means your code will have to be checked for errors before it can be built into an app. This means errors will be easier to track down. Furthermore, since statically-typed languages are also more strict with the definitions of things, you will have fewer strange and unexpected errors, which means your codebase will be easier to maintain as it grows in size and complexity.

Fast: As a statically typed language, Java is faster than dynamically typed languages because things are more clearly defined. Thus, when the app is running, your machine's resources will not be wasted on checking the definition of something in your code.

Optimized Performance: Modern Java programs are now even more performant thanks to mature JIT (just in time) compilers and improved JVMs, as performance can be optimized in real-time to help a Java program run faster. This is very helpful as your app grows larger or needs to handle more processes.

Community: Community size is important because the larger a programming language community is, the more support you'd be likely to get. As you step into the programming world, you'll soon understand how vital support is, as the developer community is all about giving and receiving help. Moreover, the larger the community, the more people will be building useful tools to make development in that particular language easier.
