Read entries in a Map<Key, Value>:

for (Map.Entry entry : entityWeight.entrySet()) {
	System.out.println(entry.getKey() + ":" + entry.getValue());
}

Open a file and append text to the end of the file:

File file = new File("X:/Spritzer/Daily/" + stringDate + ".txt");
if (!file.exists())
	file.createNewFile();
FileWriter fileWritter = new FileWriter(file, true); // append
BufferedWriter bufferWritter = new BufferedWriter(fileWritter);
bufferWritter.write("\r\n");

Date date = new Date();
SimpleDateFormat dateformat = new SimpleDateFormat("yyyyMMddhhmm");
String stringDate = dateformat.format(date);
