What are the Key Features Of Java (2023)

Introduction

Java programming is a popular class based, object-oriented programming language (OOPs). It is mainly known for its simplicity, versatility, and platform independence. It is widely used for software, web, and mobile app development. Along with this, it is also used in big data analytics and server-side technology. Whether you are a fresher or an experienced coder, the key features of Java are important for both. They are essential for building robust & scalable applications. In this blog article, we will explore all the basic key features of Java. We will explain each concept in a beginner-friendly way.


Top 10 Features Of Java Programming

Java Is Simple and Easy to Learn

As per my opinion, Java programming is the best choice for freshers who want to start a career in programming because It’s a popular language and easy to learn language. Writing code in Java is simple & similar to the syntax of the C and C++ programming languages. This similarity makes it easier to understand if you already have knowledge of those languages.


Java Is Object-Oriented Programming Language

Java is fully object-oriented which mainly focuses on objects and classes. The OOP paradigm provides a modular approach to software development, allowing for easier code reuse, maintenance, and flexibility. 

There are Four main Pillars Of Object Oriented Programming In Java – 

  • Abstraction
  • Encapsulation
  • Inheritance
  • Polymorphism 

These Four main concepts help developers to create well-organized and scalable applications.

Java is Platform Independent Language

One of the best features of Java is Platform Independence. In Java Programming, code can be executed on any platform (i.e. Windows, macOS, Linux, Ubuntu, etc.) with the help of  JVM. Also, when you write a Java program, it is first turned into something called “Bytecode”. It is then executed by the JVM. This Java feature allows it to be written once and run anywhere. Also known as WORA (Write Once, Run Anywhere).

Memory Management and Garbage Collection

Java features automatic memory management through its garbage collection mechanism. Software Developers do not need to manually allocate or deallocate memory, as the JVM takes care of memory management. The garbage collector identifies unused objects and frees up memory, reducing the risk of memory leaks and improving application performance.


Robust

Java is Robust, which means Strong because – 

  • Strong type checking enhances code reliability.
  • Exception handling allows for graceful error recovery.
  • Automatic memory management reduces memory-related issues.
  • Runtime checks prevent common programming errors.
  • Language features promote code modularity and maintainability.

Security

Bytecode Verification: Java Programming bytecode verifier checks the integrity and safety of bytecode before execution, preventing unauthorized access to memory and ensuring type safety.

Class Loading: In Java, Class-loading mechanism ensures that only trusted classes are loaded and executed, preventing the injection of malicious code.

Built-in Security APIs: Java provides many built-in security APIs such as – 

  • Encryption 
  • Authentication
  • Secure communication
  • Digital signatures
  • Access control
  • Public key infrastructure

These APIs simplify the implementation of secure features in Java applications.

One of the security benefits in Java is the absence of pointers. In Java Programming, accessing out-of-bounds arrays is prevented without the use of pointers, and any such attempt will trigger an ArrayIndexOutOfBoundsException. This protection helps safeguard against potential security vulnerabilities related to accessing memory beyond the boundaries of an array.


High Performance

As I said, one of the nicest features of Java is – its platform independence. Apart from that, it also offers high performance capabilities. In Java programming,  JIT (JIT Full Form: Just in Time) compilation optimises the performance of the code at runtime by dynamically translating the bytecode into machine code. This optimisation process, combined with efficient memory management, enables Java applications to achieve excellent performance, rivalling that of statically compiled languages.


Portable

In Java programming, the “write once, run anywhere” (WORA) principle is achieved through its portability feature. Java programs run on any platform (ex – windows, mac, ubuntu, etc.) with JVM support.  First by compiling Java code into bytecode, which is then executed by the JVM (JVM Full Form: Java Virtual Machine). This Java platform independence feature allows developers to deploy their applications across various environments without the need for significant modifications.


Interpreted

Java is a unique programming language that combines both compilation and interpretation. When you write Java code, it is first compiled into bytecode files. During runtime, the Java Virtual Machine (JVM) interprets(reads) the “bytecode files” generated from Java code. To enhance performance, the JVM employs a Just In Time (JIT) compiler that dynamically translates frequently executed bytecode into machine code. This optimization process allows for faster execution of Java programs. This combination of compilation, interpretation, and JIT compilation makes Java a versatile and efficient language for running applications.


Multi-threading 

In Java, a thread is comparable to a separate program that can run concurrently. By creating multiple threads, we can develop Java programs that handle multiple tasks simultaneously. The main benefit of multithreading is;- ‘it avoids the need for allocating separate memory for each thread’. Instead, threads share a common memory area, which makes them particularly useful for multimedia and web applications.
