Features of Java Programming Language:

Here are the key features of  Java programming language that make it widely popular:

  1. Platform Independence – Develop Once, Execute Anywhere (DOWEA).
  2. Simple and Easy to Learn – Clear syntax, akin to C/C++.
  3. Robust – Strong memory management and exception handling.

  4. Secure – Bytecode verification and no explicit pointers.
  5. Portable – Works across different platforms without modification.
  6. High Performance – Just-In-Time (JIT) compiler optimizations.
  7. Multithreading – Allows simultaneous task execution.
  8. Distributed Computing – Supports RMI and CORBA for distributed apps.
  9. Dynamic and Extensible – Links classes dynamically at runtime.
  10. Rich API – Libraries for networking, data structures, GUI, etc.
  11. Automatic Garbage Collection – Manages memory automatically.
  12. Scalable – Suitable for both small and enterprise-level applications.
  13. Open-Source – Free with extensive community support.
  14. Object-Oriented – Focuses on the utilization of objects and classes, integrating principles such as inheritance and polymorphism.

1. Platform Independence

  • You can write your code once, and it can run anywhere.
  • Java turns your code into bytecode.
  • This bytecode can run on any device with a Java Virtual Machine.

2. Simple and Easy to Learn

  • Java has a clean and easy-to-understand syntax, making it simple for beginners who are already familiar with C or C++.
  • Java is a high-level programming language i.e we will write English statement to write the code and readability of these high-level programming language is high, hence Java is considered as a simple.

3. Robust

  • Robust is one of the main features of java programming language,Java is having automatic memory management system,Java will never utilize CPU resources like RAM
  • Java uses its own architecture called JVM. It is responsible to manage the memory automatically.

4. Secure

  • The Java programming language is a highly secured programming language. Because once we write a code compiler converts our code into bite code and file extension will be in a (.class) file.
  • This (.Class) file will not be understood by anyone once after JVM decodes, it into machine, understandable language
  • Java provides built-in security features such as:
  1. Bytecode verification to detect malicious code.
  2. No explicit use of pointers, reducing unauthorized memory access.
  3. A Security Manager to define access policies for classes.

5. Portable

  • Java’s platform independence ensures that its applications are portable across various systems.
  • There is no requirement to alter the code for different platforms.
  • The concept of Java being portable signifies that you can write the code once and execute it anywhere.
  • Java programs are transformed into bytecode, which can be easily executed on any machine.

 

6. High Performance

  • Java’s Just-In-Time (JIT) compiler, which converts bytecode into machine code while it’s running, allows for optimal performance.
  • Despite generally being slower than C++, Java’s performance has significantly improved since the introduction of contemporary JVMs.

7. Multithreading

  • Because Java offers multithreaded programming, programmers can use it to carry out several activities at once.
  • Applications become responsive and efficient as a result.
  • Threads are a notion used in Java. This idea can help us do multitasking.
  • We favored the low-cost thread technique for multitasking.

8. Distributed Computing

  • Java enables the creation of networked applications through the utilization of tools such as CORBA and RMI (Remote Method Invocation).

9. Dynamic and Extensible

  • Classes can be dynamically linked at runtime in Java.
  • It allows you to load new classes without having to recompile the entire program.

10. Rich API

Java has a rich set of libraries for:

  • Socializing
  • I/O for files
  • Data structures Data Structures
  • Database connectivity
  • Swing, JavaFX, and GUI development

11. Automatic Garbage Collection

  • Java incorporates an automatic garbage collection mechanism that oversees memory usage by recovering memory from objects that are no longer in use.

12. Scalable

  • Spring, Hibernate, and Java EE are frameworks that make Java suitable for both small-scale applications and large-scale solutions.

13. Open-Source and Community Support

  • Frameworks such as Spring, Hibernate, and Java EE enhance Java’s capability, making it appropriate for applications of varying sizes, from small-scale projects to extensive enterprise solutions.

14. Object-Oriented

  • The language emphasizes the use of objects and classes, incorporating principles such as inheritance and polymorphism.
