### Question:
Utility { public static HashMap<String, String> stringToMap(String src) { HashMap<String, String> dest = new HashMap<String, String>(); if (src == null) { return (dest); } String line, key, val; int equalsPos, newLinePos, startPos = 0, len = src.length(); while (startPos < len) { newLinePos = src.indexOf('\n', startPos); if (newLinePos == -1) { newLinePos = len; } line = src.substring(startPos, newLinePos); equalsPos = line.indexOf('='); if (equalsPos != -1) { key = line.substring(0, equalsPos); val = line.substring(equalsPos + 1); } else { key = line; val = null; } dest.put(key, val); startPos = newLinePos + 1; } return (dest); } private  Utility(); static String nodeToString(Node node, int type); static String nodeToString(Node node); static Properties readProperties(String[] commandLineArgs); static byte[] read(String filename); static byte[] read(File file); static byte[] read(InputStream in); static DocumentBuilder newDocumentBuilder(); static Element getElement(

@Test public void testStringToMap() { String nvp = "ui=Fred\n" + "eng=Steve"; HashMap result = Utility.stringToMap(nvp); assertEquals(result.get("ui"), "Fred"); assertEquals(result.get("eng"), "Steve"); }
