Features of Java

Java is one of the best programming languages that permit the creation of different types of programs that can be executed on a single computer.

Java has a style that allows developers to write software compatible with any device or computer, regardless of the architecture or platform. Java is among the most used programming languages globally and is designed to run at all times on any platform.

As per the Java homepage, more than 1 billion computers and 3 billion mobile phones make use of Java to develop applications.

The advantages of Java Programming Language

These are the most advanced capabilities of Java programming, in-depth:

1. Simple and familiar

Java is easy because:

Its style of programming is clear and simple to comprehend. It eliminates complexity since it doesn't employ complicated and complicated features of other languages such as C as well as C++ that are:

  • Concept of Explicated Pointers
  • Storage classes
  • Header files and pre-processors
  • Multiple Inheritance
  • Operator Overloading
  • Go to Statements

Apart from eliminating these vague and confusing concepts, there is also a feature called automatic Garbage Collection, which removes the requirement to delete the non-referenced objects in a specific way.

Java is well-known because:

  • It is based on common languages like C and C++ and contains several features from these languages.
  • It eliminates the disadvantages of complexity, complexities and confusion in C/C++. Therefore, if you've got good skills in C/C++, you'll be able to make Java simple and simple to comprehend.

2. Compilation and Interpretation

A computer language can be written or interpreted. Java combines the capabilities of Compliable Languages and the versatility of interpretable Languages.

Java compiler (javac) compiles the Java source code into code bytecode.

Java Virtual Machine (JVM) runs this bytecode, which can be run on various operating systems and is portable.

3. Platform Independent

The main benefit of Java is the fact that it offers platform independence that leads to the possibility of portability, which eventually becomes its main advantage.

Being platform-independent implies that a program written on one computer can be run on any computer around the globe without modification. Java can achieve platform independence by applying the concept contained in BYTE. Byte Code.

The Java compiler doesn't convert source code into machine code, like the C/C++ compiler.

Instead, it converts the source code into an intermediate code known as the byte code. This code is then converted into the machine-dependent format by a different layer of software referred to as JVM (Java Virtual Machine).

Thus, JVM can execute bytecode on any platform or OS running, regardless of whether it was on a machine where the bytecode was created.

It is the place where is where the "Write Once, run anywhere" (WORA) slogan for Java comes into play. It implies that we can create applications for one operating system (OS) and then run them on another environment without making any code modifications.

4. Portable

Java can be described as "portable", which refers to the SE (Standard Edition) version. The portability comes from architectural neutrality.

For C/C++, the source code can differ slightly across different platforms. However, Java makes it easier. It is possible to run Java Bytecode on any device compatible with the JVM that can translate the bytecode by the particular hardware.

In Java, the size of the basic kinds of data is machine-independent, that were dependent when it was C/Cas well as C/C++. It makes Java applications portable across different platforms, including Windows, Unix, Solaris, and Mac.

Furthermore, any modifications and updates made to Operating Systems, Processors, and System resources won't force any changes in Java applications.

5. Architectural Neutral

It is a term used to indicate that the application written on one OS or platform is indistinguishable from any other platform or operating system and runs on any Operating System without recompiling them.

In other words, it is based on the 'Write-once-run-anywhere' (WORA) or 'Write-once-run-everywhere' (WORE) approach.

Byte code does not depend on any specific machine's architecture. Java Virtual Machine (JVM) can convert bytecode into a machine-specific language.

This feature is extremely useful in developing applets or downloading software via the Internet.

Furthermore, these programs need to be run on different computers, which is why this feature proves vital for this particular scenario.

6. Object-Oriented

The next time we write a Java feature, we will discuss how to use the OOP feature. Java is a strong supporter of the concept of OOP or Object-Oriented Programming. Because of this, it is referred to as a pure object-oriented language.

Java is a major Object-Oriented programming language that supports features such as Encapsulation, Abstraction, and Inheritance.

Nearly everything that happens in Java can be described as an object. Data and programs are all housed in classes and objects. "Objects" are the model for Java instead of the processes. Java is an extensive set of courses that are organized into packages.

For instance, we cannot create executable programs in Java without using these classes. This indicates that Java adheres to the concept of Encapsulation.

7. Robust

Java is durable because it can deal with errors during runtime, allows automatic garbage collection and handling of exceptions, and is free from explicit pointer concepts.

Java has a robust memory management technique. It assists in removing errors since it tests the code at runtime and compiles.

Java is a garbage-collected programming language. JVM automatically allocates memory blocks so that programmers don't have to think about deleting memory manually, like in C++ and other languages.

Java also supports the notion of handling exceptions which detects runtime errors and removes these.

In Java, the JVM encounters runtime errors that are not transmitted directly to the system running it. Instead, it immediately ends the program and stops it from causing damage to the system in question.

8. Secure

Security is an essential aspect of any programming language since malicious activity and viruses are risky. Java allows access modifications to verify memory access. It also ensures that viruses do not enter an applet.

Java is a safer language than C/C++ because it does not explicitly permit programmers to create pointers. In Java, we can only gain access to a specific variable if we start it up properly.

The programs run in the virtual machine Sandbox - A distinct environment where users can run their programs without impacting the system.

9. Distributed

Java is distributed because the software encourages its users to build distributed applications.

In Java, it is possible to split the program into multiple components and store them on various computers. A Java programmer on one machine can access the program on a different device.

This feature of Java provides the benefit of distributed programming, which can be highly beneficial when creating massive projects. Java assists us in achieving this through the use of RMI (Remote Method Invocation) and EJB (Enterprise JavaBeans).

Java includes a large collection of classes that can be used to interact with TCP/IP protocols like HTTP and FTP, making the creation of networks much more easily than C/Cand ++.

It also lets multiple programmers in different places collaborate on a single task.

10. Multi-threaded and Interactive

Threads are an individual execution process within the program that is running simultaneously. Multithreaded refers to handling several tasks at once or running multiple parts (functions) in the same software simultaneously.

Java's code is divided into smaller components, and Java executes the parts in an orderly and time-bound method.

Advantages:

  • The major benefit of multithreading is the optimal utilization of resources is feasible.
  • It only occupies memory for some threads. It's shared with memory space.
  • It's okay to wait for the application to complete one task before starting the next one.
  • The result is a lower cost of maintenance. Additionally, it is time-saving.
  • It increases the performance of complex applications.
