Java 10, released in March 2018, is a version of the popular programming language Java. It introduced several new features aimed at improving developer productivity and performance. One of the key enhancements is the Local-Variable Type Inference, which allows developers to use the `var` keyword for local variables, making code cleaner and easier to read. Additionally, Java 10 includes improvements to the Garbage Collection process, specifically the introduction of the G1 Garbage Collector as the default. This version also offers better performance and support for Docker containers, making it more efficient for modern application development and deployment.
