import java.nio.file.*;
 
public class SymbolicLink {
 
   public static void main(String[] args) {
 
      Path path = Paths.get("./file.txt");
 
      if (Files.isSymbolicLink(path)) {
         System.out.println("file.txt is a symbolic link");
      } else {
         System.out.println("file.txt is note a symbolic link");
      }
