Java 8 To Java 17 Conversion.

{Upgrade the following {source_language} {source_version} code snippet {source_code} to be compatible with {target_language} {target_version}. Cover the following code transformations: 1. Lambda Expressions: Convert traditional loops or anonymous classes to lambda expressions. Example: Java 8: List names = Arrays.asList("Alice", "Bob", "Charlie"); List uppercaseNames = new ArrayList(); for (String name : names) {uppercaseNames.add(name.toUpperCase());} Java 17: List uppercaseNames = names.stream().map(String::toUpperCase).collect(Collectors.toList()); 2. Var Type Inference: Use var to infer types of local variables. Example: Java 8: int num = 10; Java 17: var num = 10; 3. Diamond Operator: Simplify type inference in object creation using the diamond operator. Example: Java 8: Set mySet = new HashSet() {}; Java 17: Set mySet = new HashSet(); 4. Local Variable Type Inference for Lambda Expressions: Streamline lambda expressions with inferred types. Example: Java 8: List squares = numbers.stream().map(new Function() {@Override public Integer apply(Integer i) {return i * i;}}).collect(Collectors.toList()); Java 17: List squares = numbers.stream().map(i -> i * i).collect(Collectors.toList()); 5. HTTP Client: Modernize HTTP calls using the HttpClient API. Example: Java 8: URL url = new URL("https://www.example.com"); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("GET"); Java 17: HttpClient client = HttpClient.newHttpClient(); HttpRequest request = HttpRequest.newBuilder().uri(URI.create("https://www.example.com")).GET().build(); HttpResponse response = client.send(request, HttpResponse.BodyHandlers.ofString()); 6. Switch Expressions: Enhance readability and conciseness of switch statements. Example: Java 8: int day = 2; String message; switch (day) { case 1: message = "Monday"; break; case 2: message = "Tuesday"; break; Java 17: int day = 2; String message = switch (day) { case 1 -> "Monday"; case 2 -> "Tuesday"; 7. Text Blocks: Utilize text blocks for multi-line string literals. Example: Java 8: String longString = "This is a very long string \n" +"that spans multiple lines \n" + "and requires manual concatenation."; Java 17: String longString = """ This is a very long string that spans multiple lines without any need for manual concatenation."""; 8. {specific_prompt}.}
