Java

Java is a popular general-purpose programming language and computing platform. It is fast, reliable, and secure. According to Oracle, the company that owns Java, Java runs on 3 billion devices worldwide.

Considering the number of Java developers, devices running Java, and companies adapting it, it’s safe to say that Java will be around for many years to come.

This guide will provide everything you need to know about Java programming language before you learn it. More specifically, you will learn about features of Java programming, its applications, reasons to learn it, and how you can learn it the right way.

Java is a computer programming language. It enables programmers to write computer instructions using English-based commands instead of having to write in numeric codes. It’s known as a high-level language because it can be read and written easily by humans.

Like English, Java has a set of rules that determine how the instructions are written. These rules are known as its syntax. Once a program has been written, the high-level instructions are translated into numeric codes that computers can understand and execute.

Why Choose Java?

Java was designed with a few key principles in mind:

• Ease of Use: The fundamentals of Java came from a programming language called C++. Although C++ is a powerful language, it is complex in its syntax and inadequate for some of Java’s requirements. Java built on and improved the ideas of C++ to provide a programming language that was powerful and simple to use.
• Reliability: Java needed to reduce the likelihood of fatal errors from programmer mistakes. With this in mind, object-oriented programming was introduced. When data and its manipulation were packaged together in one place, Java was robust.
• Security: Because Java was originally targeting mobile devices that would be exchanging data over networks, it was built to include a high level of security. Java is probably the most secure programming language to date.
• Platform Independence: Programs need to work regardless of the machines they’re being executed on. Java was written to be a portable and cross-platform language that doesn’t care about the operating system, hardware, or devices that it’s running on.

The team at Sun Microsystems was successful in combining these key principles, and Java’s popularity can be traced to it being a robust, secure, easy to use, and portable programming language.
