public static void q4() { try { Scanner fin = new Scanner(new File("properties.csv")); PrintWriter pw = new PrintWriter("output.csv"); String line, name, nice; while (fin.hasNextLine()) { line = fin.nextLine(); name = line.split(",")[0]; nice = line.split(",")[4]; if(name.equals("motivation") || name.equals("orange") || name.equals("happiness")) { pw.println(name + "," + nice); } } fin.close(); pw.flush(); pw.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } }
