Understanding the Different Versions of Java

Introduction
Java is a popular programming language that is used in many applications and websites. It is a general-purpose, object-oriented language that is used to create applications for the web, desktop, and mobile devices. Java is also used in embedded systems and game development. Java is a powerful language that has been around since the mid-1990s and is still in use today. Java is available in many different versions, each with its own set of features and capabilities. Understanding the different versions of Java can help developers better understand the language and how it works.

Overview of Java Versions
The different versions of Java can be divided into three main categories: major versions, minor versions, and security updates. Major versions are the most significant updates to the language and usually include new features, bug fixes, and improved performance. Minor versions are small updates that usually contain bug fixes and minor performance improvements. Security updates are released to address any security issues that have been discovered in the language.

Major Versions
The most recent major version of Java is Java SE 11, which was released in September 2018. This version of Java included several new features, such as a new HTTP client, improved garbage collection, and a new Flight Recorder for performance monitoring. Java SE 11 also includes a new module system, which allows developers to package their applications into modules that can be easily deployed and managed.

Previous major versions of Java include Java SE 8, Java SE 7, and Java SE 6. Java SE 8 was the first version of Java to include the new lambda expressions, which are used to simplify coding and improve performance. Java SE 7 introduced the try-with-resources statement, which makes it easier to manage resources such as files and databases. Java SE 6 was the first version of Java to include the Java Virtual Machine (JVM), which allows Java programs to run on different operating systems.

Minor Versions
Minor versions of Java are released to address bugs and improve performance. The most recent minor version of Java is Java SE 11.0.7, which was released in March 2020. This version of Java includes bug fixes and performance improvements. Previous minor versions of Java include Java SE 10.0.2, Java SE 9.0.4, Java SE 8u211, Java SE 7u201, and Java SE 6u221.

Security Updates
Security updates are released to address any security issues that have been discovered in the language. The most recent security update for Java is Java SE 11.0.7, which was released in March 2020. This update includes several security fixes, including fixes for the recently discovered vulnerabilities in the JVM. Previous security updates include Java SE 8u212, Java SE 7u202, Java SE 6u222, and Java SE 5u223.
