Features of Java: Why is Java So Popular with Beginners and Experts:
Java is one of the most popular programming languages used to create applications and web platforms.Everyone who has already heard about programming knows that Java is among the main programming languages.
An important reason that contributes to the immense popularity of Java is platform independence or cross platform support. Java programs are able to run on different machines, as long as there is a Java Runtime Environment (JRE) running.
Features of Core Java :
Here are some important features of the Java programming language:
- Simple
- Oriented to Objects
- Portable
- Independent of Platform
- Protected
- Robust
- Neutral Architecture
- Dynamic
- High Performance
- Multi-Threaded
- Distributed
Simple:
The Java language is easy to learn and its coding style is easy to read and write. It contains many features of other languages, such as C and C ++, and Java removes complexity because it does not use pointers and does not support multiple inheritance.

Oriented to Object:
In Java everything is object that has some data and behavior. Java can be easily extended, since it is based on the object model.
Portable:
Being neutral in the architecture and not having aspects dependent on the application’s specification makes the Java portable. The compiler in Java is written in ANSI C with a limit of clean portability, which is a POSIX subset.
Independent platform:
This is where the slogan “Write Once, running” for Java comes in. This means that you can develop in one environment (operating system) and rotate in another environment without making any modification to the code.
Protected:
Java was designed with security in mind. As Java must be used in network / distributor environments, it implements several security mechanisms to protect it against malicious code that may attempt to invade its file system.
For example: The absence of pointers in Java makes it impossible for applications to access sites of memory without adequate authorization, since the allocation model and memory reference is completely opaque to the programmer and is completely controlled by the underlying runtime platform.
Robust:
Compiler generates bytecodes, which have nothing to do with a particular computer architecture, hence a Java program is easy to intrepret on any machine.
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 at run-time.
High performance:
Java programs are met for portable intermediate formats, known as bytecodes, instead for instructions on the level of the native machine, and the JVM executes the Java bytecode. Any machine on which it is installed.
Multi-Threaded:
The Java multithreading function enables the recording of programs that can perform several tasks simultaneously. The benefit of multithreading is that it uses the same memory and other resources to execute multiple threads at the same time, as during writing, grammatical errors are checked along.
Distributed:
Java is Distributed Language means because the Java program is compiled in A machine can easily be transferred to the machine and run on another machine because the Bytes Codes So Java facility is specially designed for Internet users who use remote computers to run their programs on the local computer after downloading the programs. remote computers or Internet.
Other benefits of Java:
In addition to the features mentioned, here are some other optimal options to choose Java over other programming languages:
- Several open source libraries.
- Supported by Oracle and the high-level support of giants of technology, such as Google and IBM.
- Large and mature community support.
- Several easily available structures to quickly create reliable applications.
- There are a lot of development environments and tools to help make Java development easier.
