Java Programming

Developed by Sun Microsystems in 1995, Java is a highly popular, object-oriented programming language. This platform independent programming language is utilized for Android development, web development, artificial intelligence, cloud applications, and much more. It is owned by Oracle, and more than 3 billion devices run Java. It’s a fast, secure, and reliable programming language that has simple rules and syntax based on the C programming languages.

Companies across the globe use Java to build the applications and websites they offer their consumers. Learning this programming language means you’ve completed one of the prerequisites that could qualify you for a career in software or app development.

Overview of Java

Java is a platform-independent, object-oriented programming language (OOP). It is not to be confused with JavaScript, a scripting language used to create dynamic web pages. Due to its reliability and ease of use, Java is one of the most popular programming languages in the world. It's likely to be one of the first programming languages you encounter as an aspiring application developer.

How does Java Work?

 To make applications in Java, you need to understand that it is both a software and programming language in one.

 You’ll need to download the Java Development Kit to code in Java. After you write your code, a compiler will transform the program into what’s known as Java bytecode so that the Java Virtual Machine can understand it.
That is another part of the Java Runtime Environment that allows programs to run just about anywhere. This is one of the biggest advantages of Java there is.

 Java consists of the Java Virtual Machine, the Java API, and a complete development environment to allow you to code powerful and flexible programs. The Java API comes with a huge library list that includes basic objects, networking, and security functions.

 When you combine everything together, the Java programming language allows you to create powerful technology for any enterprise software development.

Benefits of Using Java

1. Relatively Easy to Use
It’s easy to write and easy to understand. It’s not too difficult to maintain either. The code is easily debuggable and less complex than any of the C languages. It was based on such languages but had much of the complexities removed to allow for a more streamlined coding experience.

2. Object-Oriented Programming Language
Java helps you improve the flexibility and reliability of all the code you create. It uses the concepts framed under object-oriented languages so that you can easily reuse the same objects in different programs to make things as convenient as possible.

Java is used to bind the data and function into a single unit so that security is improved. The bigger modules are broken down into smaller modules so that they’re easier to handle and understand. That is another one of those famous Java benefits.

3. Java is Secure
Java avoids using explicit pointers. That reduces the amount and severity of security threats you’ll encounter. These can result in unauthorized access to the memory, but simply removing pointers altogether solves this problem. Java also comes with a security manager for each application to define access rules for classes.

4. Not Expensive to Maintain
Java programs are dependent on specific hardware infrastructures to run. That means you can easily execute them on any machine and reduce the overall cost of maintaining the application.

5. Heavily Platform-Independent
Java lets you use a compiled core that’s platform-independent. It can run on any machine and any operating system. It makes full use of the Write Once Run Anywhere system feature. Any machine that has the Java Virtual Machine can execute Java code.

6. High-Level Programming Language
Java is a high-level programming language and has a deceptively simple syntax that’s easy to maintain and intuitive to learn.
That’s one of the stand-out features of Java that developers end up falling in love with.

A high-level language is one that’s easy for humans to understand and write.

7. Super Portable & Stable
Java has platform independence like very few other tools out there. It can run on any platform and execute with ease. This portable superiority dramatically improves the applications of Java in all situations.

Java programs have been shown to be much more stable when compared to programs made with other languages. Each new version of Java comes with a heap of features and increases instability as well. Its stability is one of the primary reasons why the importance of Java can never be understated.

8. Supports Multi-Threading
Java can run on more than one thread at the same time. A single thread is the smallest possible unit of a process. Running on more than one thread allows you to make maximum use of the CPU to make the user experience a pleasant one.

9. A Distributed Language
Java has mechanisms in place to share data and programs among multiple computers. That improves the overall efficiency and performance of programs coded in Java. In particular, it also supports Socket Programming and CORBA, which helps in sharing objects in a distributed environment.
