    Assuming path is your String.

    File file = new File(path);
    
    boolean exists =      file.exists();      // Check if the file exists
    boolean isDirectory = file.isDirectory(); // Check if it's a directory
    boolean isFile =      file.isFile();      // Check if it's a regular file
    

    See File Javadoc


    Or you can use the NIO class Files and check things like this:

    Path file = new File(path).toPath();
    
    boolean exists =      Files.exists(file);        // Check if the file exists
    boolean isDirectory = Files.isDirectory(file);   // Check if it's a directory
    boolean isFile =      Files.isRegularFile(file); // Check if it's a regular file
