What is Java?
Java is a widely-used programming language for coding web applications. It has been a popular choice among developers for over two decades, with millions of Java applications in use today. Java is a multi-platform, object-oriented, and network-centric language that can be used as a platform in itself. It is a fast, secure, reliable programming language for coding everything from mobile apps and enterprise software to big data applications and server-side technologies.


What is the use of JAVA?
Java is popular because it has been designed for ease of use. Some reasons developers continue to choose Java over other programming languages include:

High quality learning resources :
Java has been around for a long time, so many learning resources are available for new programmers. Detailed documentation, comprehensive books, and courses support developers through the learning curve. In addition, beginners can start writing code in Core Java before moving to Advanced Java.

Inbuilt functions and libraries :
When using Java, developers don’t need to write every new function from scratch. Instead, Java provides a rich ecosystem of in-built functions and libraries to develop a range of applications.

Active community support :
Java has many active users and a community that can support developers when they face coding challenges. The Java platform software is also maintained and updated regularly.

High-quality development tools :
Java offers various tools to support automated editing, debugging, testing, deployment, and change management. These tools make Java programming time and cost-efficient.

Platform Independent :
Java code can run on any underlying platform like Windows, Linux, iOS, or Android without rewriting. This makes it especially powerful in today’s environment, where we want to run applications on multiple devices.

Security :
Users can download untrusted Java code over a network and run it in a secure environment in which it cannot do any harm. Untrusted code cannot infect the host system with a virus nor can it read or write files from the hard drive. The security levels and restrictions in Java are also highly configurable.

Socket Programming

What is Socket Programming ?  A   socket   is a communications connection point (endpoint) that you can name and address in a network. Socket programming shows how to use socket APIs to establish communication links between remote and local processes. The processes that use a socket can reside on the same system or different systems on different networks. Sockets are useful for both stand-alone and network applications. Sockets allow you to exchange information between processes on the same machine or across a network, distribute work to the most efficient machine, and they easily allow access to centralized data. Socket application program interfaces (APIs) are the network standard for TCP/IP. A wide range of operating systems support socket APIs. i5/OS sockets support multiple transport and networking protocols. Socket system functions and the socket network functions are thread safe.                                  Programmers who use Integrated Language Environment® (ILE) C can re
