It sounds like homework.
public static void main(String[] args) throws IOException { // first, let build your hashmap and populate it HashMap<Integer, String> map = new HashMap<Integer, String>(); map.put(1, "Value1"); map.put(2, "Value2"); map.put(3, "Value3"); map.put(4, "Value4"); map.put(5, "Value5"); // then, define how many records we want to print to the file int recordsToPrint = 3; FileWriter fstream; BufferedWriter out; // create your filewriter and bufferedreader fstream = new FileWriter("values.txt"); out = new BufferedWriter(fstream); // initialize the record count int count = 0; // create your iterator for your map Iterator<Entry<Integer, String>> it = map.entrySet().iterator(); // then use the iterator to loop through the map, stopping when we reach the // last record in the map or when we have printed enough records while (it.hasNext() && count < recordsToPrint) { // the key/value pair is stored here in pairs Map.Entry<Integer, String> pairs = it.next(); System.out.println("Value is " + pairs.getValue()); // since you only want the value, we only care about pairs.getValue(), which is written to out out.write(pairs.getValue() + "\n"); // increment the record count once we have printed to the file count++; } // lastly, close the file and end out.close(); }
