Description
Before :
List<String> elements = List.of("Hello","World");
for (int i = 0 ; i < elements.size(); i++){
System.out.println(elements.get(i));
}
After :
List<String> elements = List.of("Hello","World");
for (String element : elements) {
System.out.println(element);
}

Research direction
Start by reviewing the repository's existing static-analysis recipes and tests to find where a recipe for Java indexed loops belongs. Compare the issue's before and after examples and the linked enhanced-for-loop reference. Done means the recipe identifies the shown index-based iteration pattern and verifies the enhanced-loop result with tests.
