Как найти строку в txt файле?

File file = new File("src/main/resources/textfile.txt");

	Scanner scanner = new Scanner(file);
	try {
	    
	    while(scanner.hasNextLine()) {
		String line = scanner.nextLine();
		
		String[] cols = line.split(" ");
		
		if (cols[4].equals("17.08.2015")) {
		    System.out.println(line);
		}		
	    }
	    
	} finally {	    
	    scanner.close();
	}
