There are more languages than 250 used today in programming. Coding is a highly profitable and scalable skill. According to, Java was the most in-demand programming language in America in 2019, with 69,000 jobs in a single calendar year.
Java is a topic that you have probably heard a lot about in the context of boot camps or basic computer programming. Programming languages like Java are used by web developers. They focus on the back-end functionality and make sure that the software works well, rather then focusing on the design and appearance of the website. JavaScript developers take care of this.
It is easy to use and developers with different skill levels can easily learn it.
What is Java?
C++ was the most popular back-end programming language used for business application development before 1991. It was a complicated language and platform-dependent. James Gosling and Sun Microsystems’ team launched Java in 1991 to simplify app building for developers and businesses. Java was created to be an object-oriented, interpretable programming language that also supports multi-threading programming.
You now know the basics of Java.
1. Simple:
Java’s simplicity is one of the reasons Java is more popular that C++. It eliminates complexity like operator overloading and pointers that are common in C++ and other programming language.
2. Portable:
Java doesn’t compile in the same way as C++. C++ compiles the program to machine code that is specifically designed for a particular chipset. Java is platform-independent, which means code written for one platform can easily be ported and used on another platform.
3. Object-oriented:
Java, and specifically its JVM component considers everything an ‘object’ with some inherent state or behaviour. These objects are used for all Java operations.
4. Secure:
All Java code is converted to bytecode after compilation. This code is unreadable by humans. Java doesn’t use an explicit pointer, and runs its programs in the sandbox. This prevents malicious activities from unauthorised sources. This allows users create virus-free software and systems that cannot easily be altered.

5. Dynamic:
Java is able to adapt to changing environments. It supports dynamic memory allocation, which reduces memory wastage while improving the performance of the application.
6. Distributed:
Remote Method Invocation (RMI) allows Java programs to invoke the methods of other Java programs across a network and receive the output. Java makes it possible to create distributed applications by using this feature.
7. Robust:
Java uses strong memory management systems. It inspects the code during compile, runtime, and when it is executed.
