In 1995, James Gosling, famously known as the Father of Java developed it. Java is anisland in Indonesia where the first coffee (java coffee) was produced. While having coffee near his office, James Gosling chose this name.

Why choose Java?

It is Platform Independent

Java Virtual Machine executes the bytecode produced by the compiler. Operating Systems have different JVM, but the result they produce after the execution is the same across all the operating systems. Thus, Java is popularly called a platform-independent language.

It Supports OOPS (Object -Oriented Programming)

It enables organizing the program in terms of the collection of objects, each representing an instance of the class.

It is Simple

Java is one of the simplest languages because it does not have complex features like multiple inheritances, explicit memory allocation, and the like. It is thus easy to learn and progress to advanced levels.

WORA

Java applications are called WORA (Write Once Run Anywhere) because you can develop Java code on one system and run it on any other Java-enabled system without any adjustment.

It is reliable

The main features of Java, likegarbage collection, Exception Handling, and memory allocation, make it reliable. It is built to check errors as early as possible and detect problematic errors that other programming languages might miss.

It is Secure

Due to a lack of pointers, it is impossible to access out-of-bound arrays; if we do, it will throw an ArrayIndexOutOfBound Exception. Additionally, Java programs are independent of the OS (operating system), making java programs more secure.

It is Portable

You can carry java bytecode into any platform. (Set of instructions for JVM is called bytecode; code lies between low-level and high-level language).

Multithreading

Java supports multithreading, thus facilitating the simultaneous execution of two or more program segments for maximum CPU utilization.

High Performance

Java architecture reduces overhead during the runtime. For example, using the Just In Time (JIT) compiler, you can compile code on-demand where it only compiles those methods that are called, facilitating faster execution.

Applications that use Java

• Mobile App Development- Developing Mobile Applications, and most android applications are made using Java
• Desktop GUI Applications-program enables to perform communication through Symbols; Java provides tools such as AWT, JavaFx, and Swing
• Web-based Applications- we can create Web Applications using JSP, Servlets, Spring Boot
• Gaming Technologies-Java supports powerful 3D Engine Games such as MissionImpossible3, Minecraft, etc.
• Cloud Applications- Java develops SAAS (Software AsA Service) and PAAS (Platform AsA Service)

Top companies using Java

• Netflix
