There are six categories of HTML elements. Void element is one among the six categories that have the following HTML elements. Void elements or tags do not need the closing tag and always be closed in the same opening tag, that's why we also refer to these elements as self-closing elements. Void elements can't have child elements or content.

Mark filed and method injection optional.
To manage the ambiguity between injector, it helps us to tie the injected field or method to a particular injector.

Java 11, released in September 2018, introduced several new features and improvements. Here is a summary of the release notes and some of the key new features in bullet points along with examples:
1. Local-Variable Syntax for Lambda Parameters
- Allows using `var` as the type of lambda parameters.
- Example:
// Before Java 11 (String str) -> System.out.println(str); // Java 11 and later (var str) -> System.out.println(str);
2. HTTP Client (Standard)
- The new `java.net.http.HttpClient` API provides a more modern and efficient way to send HTTP requests and receive responses.
- Example:
HttpClient client = HttpClient.newHttpClient(); HttpRequest request = HttpRequest.newBuilder() .uri(URI.create("https://api.jorvee-java.com/java-sample")) .GET() .build(); HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString()); System.out.println(response.body());
3. Enhanced `java.util.stream` API
- New methods like `takeWhile`, `dropWhile`, `ofNullable` for Stream and Optional.
- Example:
List<Integer> numbers = List.of(1, 2, 3, 4, 5); // takeWhile List<Integer> result1 = numbers.stream() .takeWhile(n -> n < 4) .collect(Collectors.toList()); // Output: [1, 2, 3] // dropWhile List<Integer> result2 = numbers.stream() .dropWhile(n -> n < 4) .collect(Collectors.toList()); // Output: [4, 5] // ofNullable Optional<String> optionalValue = Optional.ofNullable(null);
4. `var` in Lambda Expression
- Allows using `var` in lambda expressions, capturing the type from the context.
- Example:
BiFunction<Integer, Integer, Integer> add = (var x, var y) -> x + y;
5. Epsilon: A No-Op Garbage Collector
- Introduces a new garbage collector (`-XX:+UseEpsilonGC`) that does not reclaim memory but allows applications to run without GC overhead.
- Useful for performance testing or short-lived applications with minimal memory allocation.
6. Nest-Based Access Control
- Adds support for private interfaces, allowing nested classes to access private members of the enclosing class.
class Outer { private interface InnerInterface { void doSomething(); } static class Nested implements InnerInterface { public void doSomething() { System.out.println("Doing something..."); } } }
7. Flight Recorder
- Previously commercial feature, now available for free in OpenJDK.
- Flight Recorder allows recording and analyzing application events for profiling and debugging purposes.
These are just a few of the new features and improvements introduced in Java 11. The release also includes performance enhancements, security updates, and other improvements. Always ensure to check the complete release notes and documentation for a comprehensive overview of all changes and updates.

Alaska was earlier part of the Russian Empire. Russia sold Alaska to the United States for 7.2 million US dollars in the year 1867. The Senate approved the treaty of purchase on April 9; President Andrew Johnson signed the treaty on May 28, and Alaska was formally transferred to the United States on October 18, 1867.

First, we have to create an object of ResourceResolver either using ResourceResolverFactory or using session. In this example, we use ResourceResolverFactory interface service API to create the object of ResourceResolver to get the resource from AEM. (code snippet line # 6)
Now we will get the resource using ResourceResolver and adapt that resource in a JCR Node type, so we can deal with that resource and perform manipulation. ResourceResolver has a method getResource resource which makes AME resource available for manipulation. getResource() method required a relative to as parameter to get that resource. (code snippet line # 7)
Then using JCR API we will add a node under that resource/Node with its name(component name) and type(component type). (code snippet line # 8)
After that, we will set all the required property for that component. (code snippet line # 9-13)
