Java is an object-oriented programming language that was first released in 1995. It is widely used because it is platform independent, secure, and has features like automatic garbage collection and multithreading. Some key features of Java include its support for object-oriented concepts like inheritance, polymorphism, and encapsulation. Java code can run on any device because it is compiled to bytecode, which can be run by a Java virtual machine regardless of the underlying hardware or operating system. The document promotes a company called Chetu that provides custom Java development solutions and includes their contact information.
3. Introduction
■ Java is an object oriented general purpose computer programming language. It was
first released in 1995 by “James A Gosling” by Sun Microsystems. Java is widely used
in application development because it’s secure, fast, reliable and free. Java’s compiled
code can run on any operating system such as Windows, Linux, Mac and Android.
4. Why Java
■ There are many Java features that makes it a programmer’s favorite language.
■ Object Oriented
■ Platform Independent
■ Simple:
■ Secure
■ Multithreading
■ Automatic Garbage Collection
5. Object Oriented
■ Java is an object oriented programming language, it supports all the OOP features
such as encapsulation, polymorphism, inheritance and abstraction.
6. Platform Independent
■ It is not exclusive to any specific operating system or processor. It’s a
platform independent language called Java byte code or intermediate code.
It can be run on any platform and interpreted by the virtual machine. Hence,
there is no need to re compile after compiling once, it can be run anywhere.
7. Simple
■ If the programmers OOP concept is clear. Java code is very easy to write and
understand.
8. Secure
■ Java language’s static type checking and run time checking shows its security
features. Java platform is completely secure from any kind of virus and tamper for
application development.
9. Multithreading
■ Java supports the features of multithreading. It allows concurrent thread’s activity The
programming language is very helpful for creating highly interactive and responsive
applications.
10. Automatic Garbage Collection
■ Java is a robust programming language. It consists the feature of automatic
garbage collection and memory management that are very helpful to build highly
reliable applications.
11. ■ Besides all, few more important features are portable, high performance, dynamic.
■ In the real World use of Java: Java is a widely preferred programming language. It
is frequently used in many industrial development platforms such as building
scientific applications, mobile applications, gaming app, enterprise applications,
desktop application, web services, application server and web server.
12. Final thought
■ In 21st century, technology has become inseparable parts of our lives. Java
technology is secure and reliable. There are many software development
companies that offer custom Java software development solutions
