Source Code

import java.io.*;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class FileOperator17Example { 
	public static void main(String[] args) {

		try
        {
			File path = new File("example.txt");
	       	if (!path.exists()) 
	       	{
	       		path.createNewFile();
	       	}
    		FileReader reader = new FileReader(path);
    		BufferedReader br = new BufferedReader(reader);
    		int lines = 0;
    		while (br.readLine() != null) 
    		{
    			lines++;
    		}
    		 System.out.println("Lines : " + lines);
        } 
        catch (IOException e)
