public class Demo {

        Properties prop = new Properties();
        String s = "Height=200";
        String s2 = "Width=15";

        try {

            // create a new input and output stream
            FileOutputStream fos = new FileOutputStream("properties.txt");
            FileInputStream fis = new FileInputStream("properties.txt");

            // write the first property in the output stream file
            fos.write(s.getBytes());

            // change the line between the two properties
            fos.write("\n".getBytes());

            // write next property
            fos.write(s2.getBytes());

            // load from input stream
            prop.load(fis);

            // print the properties list from System.out
            prop.list(System.out);
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
