Features of Java: the Java Buzzwords and its Benefits in 2024 | ITpreneur

Released in 1995 by Sun Microsystem, Java is one of the most popular programming languages. It’s a portable, simple, secure, object-oriented language with automatic memory management, a robust type system, built-in support for multithreading and security, a rich API, high performance, scalability, and simplified syntax.

In this blog, we will discuss these features of Java, also known as Java Buzzwords, in detail and learn the advantages of features of Java programming and their importance in software development.

Major Features of Java 

1. Simple and Easy to Learn

Java is easy to learn and simple to use as a programming language. It is because of following reasons:

  • Java comprises the same syntax as C, and C++.
  • It holds automatic garbage collection features.
  • Java eliminated its unused features.
  • It keeps bringing regular updates for better performance.

Java has its own community to make learning and using Java easy.

2. Object-Oriented Programming

Almost everything written in Java is object and class, making it a true object-oriented programming (OOP) language. The basic concept of OOP is:

  • Object: Object is a real-world entity in Java that encompasses state, functionality, and identity.
  • Class: Class is a logical entity which includes a group of objects with common properties. It contains fields, methods, constructors, blocks, nested classes and interfaces.
  • Inheritance: It’s a concept in Java through which developers can create new classes built upon existing classes to achieve runtime polymorphism.
  • Polymorphism: A Mechanism in Java through which you can perform a single action in multiple ways. Polymorphism can be of two types- Compile time and runtime.
  • Abstraction: It’s a method to hide internal processing and show only essential things to the users.

3. Platform Independence

Unlike other languages, Java is not limited to any specific machine and dependent on other factors to run. The Java platform is independent because:

  • It uses a runtime environment of its own, i.e. JVM.
  • It is a write-once, run-anywhere language.
  • It is a software-based platform that runs on top of other hardware-based platforms.
  • Its code can be executed on multiple platforms, including Windows, Linux, Sun Solaris, and Mac/OS.
  • The Java code is compiled by the compiler and converted into bytecode.

4. Automatic Memory Management

Automatic memory management is a crucial feature of Java programming. It helps in:

  • Create high-performance system.
  • Automatically allocate and free up space for objects.
  • Eliminating the worries about memory management.
  • Issues like object destruction don’t occur.
  • There is no need to add memory management logic.

5. Security

Java programming language is known for its security. With it, you can create virus-free systems because:

  • Java programming language runs inside a virtual machine.
  • It uses its own runtime environment- JVM.
  • Java includes a security manager, which determines what resources a class can access, such as reading and writing to the local disk.
  • In Java run time, a class loader separates the package for the classes of the local file system from the files imported from network sources.
  • Java also consists of Bytecode Verifier, which checks the code fragments for illegal code.

6. Rich API

Being one of the oldest programming languages, Java has a rich API. Some popular Java APIs are:

  • Java Advanced Imaging (JAI)
  • Java Data Objects (JDO)
  • Java Media Frameworks (JMF)
  • Java Persistence API (JPA)
  • Java 3D (J3D)

7. Multithreading

Multithreading is an essential feature of Java that makes Java programming exclusive. It offers several benefits:

  • It lets Java developers execute multiple threads at the same time.
  • It’s used to achieve multitasking.
  • It saves time.
  • It’s mostly used in games and animation.
  • Threads work independently and don’t impact other threads, even if created simultaneously.

8. High Performance

Java is a programming language with a high-performance rate. It is because:

  • Java uses bytecode that can be easily translated into native machine code.
  • It has multiple easy-to-use frameworks.
  • It is compatible with multiple platforms, including Windows, Linux, Sun Solaris, and Mac/OS.
  • It is a write-once, run-anywhere language.
  • Java also automatically clears the garbage to enhance its performance.

9. Scalability

Java offers its users scalability, which means it can deal with more and more users and works. It is so because:

  • Java is an object-oriented programming language.
  • It has the ability to handle large databases.
  • Java doesn’t require multiple resources while running.
  • It uses multithreading and multiprocessing.\
  • Java includes a higher volume of code.

10. Simplified Syntax

Java is one of the most used programming languages with simplified syntax. Some basic features of writing syntax for Java:

  • Java programming language is easily understood by the compiler and computer.
  • It is case-sensitive, which means “hello world” or “HelloWorld” are two different things.
  • It includes a bunch of objects and classes.
  • The Java code statements end with semicolons (;).
  • In Java syntax, there are delimiters “{…}” that denote a block of code.
