Java is a widely-used programming language known for its platform independence, allowing programs to run on various computer systems equipped with a Java Runtime Environment (JRE). It remains popular among large organizations and is an evolving language that combines stability with innovation, making it worth learning for new developers due to its ease of syntax. With approximately 10 million developers globally, Java is increasingly recognized for its applications in mobile, desktop, industry servers, Internet of Things (IoT), and cloud development.

3. Why is Java so popular?
One of the biggest reasons why Java is so popular is the platform independence.
Programs can run on several different types of computer; as long as the computer has
a Java Runtime Environment (JRE) installed, a Java program can run on it.
Most types of computers will be compatible with a JRE including PCs running on
Windows, Macintosh computers, Unix or Linux computers, and large mainframe
computers, as well as mobile phones.
Since it has been around for so long, some of the biggest organisations in the world are
built using the language. Many banks, retailers, insurance companies, utilities, and
manufacturers all use Java.
Steve Zara, a programmer for more than 40 years, describes how there is no sign of
Java declining in use. Instead, it is an evolving language which almost uniquely
combines stability with innovation.
Highlighting the longevity of the language, Zara states that the code you may have
written 15 years ago will run on the most up-to-date JVMs and gain the speed
advantage of the latest profiling, native code translating, and memory management.

4. Is Java worth learning?
Java is still a relevant programming language that shows no sign of
declining in popularity and, for that reason, is worth learning. Most
developers pick it up as their first programming language because
it’s reasonably easy to learn.
Since the language has an English-like syntax with minimum special
characters, Java could be learned in a short time span and used to
build suitable applications.
Java is part of a family of languages that are heavily influenced by
C++ (as well as C#), therefore learning Java offers vast benefits
when learning these other two languages.

5. The importance of Java
Java is an all-around universal programming language. Due to its solidity
and scalability, Java is found on mobiles, desktops and large-scale
industry servers and applications.
Recently, Java has been gaining credibility in the area of Internet of
Things (IoT) and cloud development.
Globally, there are around 10 million Java developers, and this
community continues to grow on a daily basis. Similar to other open
source technologies, Java encourages the values of giving back to the
public.
Online forums, such as StackOverflow, consists of Java developer
experts who are ready to help beginners.
