Java 13 to Java 16: Iterative Improvements

• The subsequent versions, from Java 13 to Java 16, predominantly concentrated on delivering incremental improvements. Java 13 introduced text blocks, a useful feature for writing multiline strings. Java 14 incorporated switch expressions as a standard feature, previewed in Java 12. Java 15 and Java 16 continued this trend of small, targeted enhancements, including features like sealed classes and pattern matching for the instance of operator.

Java 17: The Latest Milestone

• Java 17, released as the latest long-term support (LTS) version, further cements Java’s position as a cutting-edge language. It introduces several exciting features, including sealed classes and interfaces, enabling developers to restrict inheritance, enhancing security and design. It also includes pattern matching for switch, making code more readable and expressive.
  Moreover, Java 17 comes with enhanced foreign function and memory APIs, enabling seamless integration with non-Java code and native memory. The introduction of extended support for the latest standard and preview features promises a stable and innovative platform for application development.

The Significance of Java 17 and Beyond
Java’s evolution through its various versions signifies a commitment to innovation while maintaining backward compatibility. Java 17’s release emphasizes not only the language’s ongoing development but also its robustness, security, and readiness for modern software development challenges.

any graduates often ask me, which is the best programming language, which language should we learn, shall I learn Java, Python, etc. Well, it depends upon the definition of your best programming language, if it is popularity, then obviously Java outscores everyone. There is a long list of programming languages that continue to exist with their strengths and flaws, making our lives easier. However, I strongly don’t believe in any type of competition between different programming languages. Java is one of the best programming languages created ever, and I am not saying this because I am passionate about Java, but Java has proved it in last 20 years. During its journey, this free and open source programming language has achieved numerous milestones and proved its worth. The recent indexes of programming languages popularity have once again reinforced that Java is one of the most popular languages around.

In this blog, I will share my list of reason, and why you should learn Java programming and make a career out of it.

Java is Object Oriented Programming language. Java is a general-purpose programming language that can run on virtually any type of computer and is independent of both device and platform. It promised “Write Once, Run Anywhere” (WORA), providing no-cost run-times on popular platforms. Fairly secure and featuring configurable security, it allowed network- and file-access restrictions. J2EE included technologies and APIs for enterprise applications typically run in server environments.

There are few below facts of Java Programming

Nearly 9 of every 10 computers in the US runs Java.

3 Billion Devices run Java

There are 9 million java developers worldwide.

1 Billion Java Downloads per Year
