Exploring the New Features of Java 11
Java 11 features
Java 11, released in September 2018 as a Long-Term Support (LTS) version, introduced several significant features and enhancements aimed at improving developer productivity and application performance. Key features include the new HTTP Client API (java.net.http), which simplifies the process of making HTTP requests and handling responses, and the removal of the Java EE modules, allowing developers to rely on external libraries for these functionalities. Additionally, Java 11 introduced the “var” keyword for local variable type inference, enhancing code readability, and new string methods like `isBlank()`, `lines()`, and `strip()`, which simplify string manipulation. The release also includes performance improvements, a garbage collector (ZGC), and several deprecations to clean up the API, fostering a modern coding experience. Overall, Java 11 solidifies its position as a robust platform for developing enterprise applications with a focus on simplicity and efficiency.

1 - Local Variable Syntax for Lambda Parameters: Java 11 allows the use of the `var` keyword in lambda expressions, making it easier to declare complex types.
2) New String Methods: Introduced methods like `isBlank()`, `lines()`, and `strip()` for improved string manipulation. `isBlank()` checks if a string is empty or contains only whitespace.
3) Java Flight Recorder: A low overhead data collection framework for profiling and diagnostics. It helps monitor applications in production without impacting performance significantly.
4) Dynamic Class File Constants: New `ConstantDynamic` feature enhances JVM's ability to handle dynamic constants, improving efficiency for certain class loading operations.
5) HTTP Client API: A new standardized HTTP Client API for making HTTP requests. Supports HTTP/2 and web sockets, making it easier to work with modern web applications.
6) Z Garbage Collector (ZGC): A low latency garbage collector that aims to handle large heaps without significant pause times. It is experimental but useful for applications requiring low response times.
7) Removed the Java EE and CORBA Modules: The removal of modules suggests a shift towards a more streamlined Java, reducing legacy support and focusing on modern development needs.
8) New File Methods: Added methods in the `Files` class, such as `readString()`, `writeString()`, and methods to copy files with more options, improving file handling.
9) Nest Based Access Control: Support for nested classes that can access each other's private members directly, simplifying access control between closely related classes.
10) Epsilon Garbage Collector: An experimental garbage collector that does not reclaim memory, allowing developers to test memory allocation without actual memory management, useful in certain scenarios.
11) Collection.toArray() Enhancements: New overloads for `toArray()` allow developers to create arrays with specified types more conveniently.
12) Launch Single File Source Code Programs: Directly run a single Java source file with `java <filename>.java`, simplifying the execution of quick scripts and improving developer productivity.
13) Improved Aarch64 and Other JVM Features: Various enhancements to improve performance and support for specific hardware architecture, including AArch64 (ARM), making Java more versatile across platforms.
14) Deprecation of the Applet API: As web technologies have evolved, the Applet API has been deprecated, reflecting a shift away from this older method of executing Java code on the web.
15) JEP 330 Launch Single File Source Code Programs: This enhancement simplifies the execution of Java source files, allowing developers to write and run small programs quickly without needing to compile them first.
These features of Java 11 not only enhance the capabilities of the programming language but also streamline development practices, making it an excellent choice for both beginners and experienced developers.
