New features and enhancements in Java 10

Java 10, released in March 2018, is a version of the Java programming language that introduced several new features and functionalities.

1. Local variable type inference: Java 10 introduced the var keyword, allowing for type inference in local variable declarations. The compiler can automatically deduce the type of a variable based on its initialization value.
2. Parallel Full Garbage Collector: Java 10 introduced a new parallel full garbage collector that utilizes multiple processor cores during garbage collection to enhance performance.
3. Application Class Data Sharing (ACDS): Java 10 allows for the sharing of application class data between multiple Java virtual machine instances in order to reduce JVM startup time and memory usage.
4. Standardized HTTP client: Java 10 introduced a standardized HTTP client API for sending HTTP requests and receiving responses, providing a simpler and more flexible way to communicate over the network.
5. Thread-Local Handshakes: Java 10 introduced a new mechanism that allows threads to perform handshakes before and after specific operations. This mechanism can be used to optimize the performance of thread synchronization.
6. Experimental time-based garbage collector: Java 10 introduced a new experimental garbage collector that performs garbage collection based on the lifespan of objects to improve efficiency.
7. Other enhancements: Java 10 also includes some other improvements, such as enhancements to the G1 garbage collector on heap memory, enhanced thread-local variables, and a better logging API.

These are some of the key new features and functions in Java 10 that can enhance developers’ productivity and code performance.
