New to Java

Hello,

I would like to count the number of lines for each file in my directory and subdirectories.
I wonder how can I count the lines of the specified files?

Here is the program which is listed the files in the specified directory:

                    String path = "C:/User/Studies/Pracices/src/Pract1";
	  String files;
	  File folder = new File(path);
	  File[] listOfFiles = folder.listFiles(); 
	 
	  for (int i = 0; i < listOfFiles.length; i++) 
	  {
	 
	   if (listOfFiles.isFile()) 

	{

	files = listOfFiles[i].getName();

	

	System.out.println(files);

	}

	}
