Is it possible to traverse document lines using lazy data initialization?

Yes, in Java it is possible to traverse document strings using lazy initialization, for example, with streams or iterators that load and process lines as needed, rather than all at once.

An example using the Stream API to read a file line by line:

import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.stream.Stream;

public class LazyFileReader {
    public static void main(String[] args) {
        String filePath = "path/to/file.txt";
        try (Stream<String> lines = Files.lines(Paths.get(filePath))) {
            lines.forEach(line -> {
                // Process the line
                System.out.println(line);
            });
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

The Files.lines() method returns a Stream that reads the file lines lazily as it traverses, which helps save memory when working with large files. Thus, data is initialized lazily — lines are loaded only when needed.
