New Features in Java 11

Java 11 introduces several new features and improvements. Let's take a look at some of them:

Local-Variable Syntax for Lambda Parameters

Java 11 allows the use of var keyword for lambda parameters. This simplifies the syntax and makes the code more concise. Here's an example:

(var x, var y) -> x + y

HTTP Client

Java 11 comes with a new built-in HTTP client library that provides support for HTTP/2 and WebSocket. This library simplifies the process of sending HTTP requests and handling responses. Here's a simple example:

import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;

public class HttpClientExample {
    public static void main(String[] args) throws Exception {
        HttpClient client = HttpClient.newHttpClient();
        HttpRequest request = HttpRequest.newBuilder()
                .uri(URI.create("
                .build();
        HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());
        System.out.println(response.body());
    }
}

Improved Security

Java 11 includes improvements in the security area. It provides support for TLS 1.3, which is the latest version of the Transport Layer Security protocol. This enhances the security of Java applications that communicate over the network.
