Introduction to Java
Java is a versatile and secure programming language, famous for its reliability in the developer community. It is known as one of the earliest object-oriented languages. Java's robust features support various applications—from Android and desktop development to enterprise solutions and cloud computing. It is also recognized as one of the top languages developers want to learn. Java’s applications in tech are both vast and valuable. In this article, we will look into Java's fundamental features, and its application in various domains, and provide examples to make things easier for you to understand.
Features of Java:
Platform Independent
It has a core philosophy of Write Once, Run Anywhere. Java is compiled into a platform-independent form – Byte Code.
Byte-Code can be run on any machine which is interpreted by the Java Virtual Machine(JVM) installed on them.
Object-Oriented
It started as a language to overcome the limitations of C++.
It is a purely object-oriented programming language. The object-oriented approach makes Java secure, reliable, and scalable.
What Is Object-Oriented Programming?
Object-oriented programming is a paradigm of programming. The other commonly known paradigms of programming are functional programming, procedural programming, and task-oriented programming.
Object-oriented programming is based on objects which contain data and methods (functions). It promotes modularity and reusability.
The important features of Object-oriented programming are:
- Abstraction
- Inheritance
- Encapsulation
- Polymorphism
- Secure
Language before Java such as C++ had a major drawback of security. It has features to ensure enterprise-level security in its applications.
The features such as runtime checking, no use of pointers, exception handling, access control and type-checking, are responsible to provide such high-security standards to Java.
Simple
It is simple syntax and great readability due to the modular nature of code. It is easy for a beginner to start off and understand the key principles of the language.
Robust
It is a robust programming language. It is termed robust or strong for its strong features such as efficient memory management, automatic garbage collection, exception handling, and type checking.
These features make it the preferred language to develop huge enterprise applications with ease and reliability.
Architecture Neutral
It has solved the binary-distribution problem. It converts the code into a “binary code format” that is independent of hardware architectures, operating system interfaces, and window systems.
Its run-time platforms are used for different hardware and software environments.
Any Java code written on any system configuration can run on any different system without the need to change the code. The format of “Byte code format is system independent making it architecture-neutral.
Multi-threaded
It gives you the ability to run multiple processes together to maximize the utilization of the CPU.
These threads are run in parallel. It is also known as concurrency in Java. As a developer, using the multithreading feature of it you can build interactive applications.
High Performance
It has Just-In-time compilers that make it faster and enable high performance.
