Method

voidprintHash(HashMap hashMap)
print Hash 
Set<?> s = hashMap.entrySet();
Iterator<?> it = s.iterator();
while (it.hasNext()) {
    Map.Entry m = (Map.Entry) it.next();
    System.out.println(m.getKey() + "\t" + m.getValue());
voidprintHash(HashMap hashMap)
HashMap Operations 
System.out.println("Print HashMap");
Set s = hashMap.entrySet();
Iterator it = s.iterator();
while (it.hasNext()) {
    Map.Entry m = (Map.Entry) it.next();
    System.out.println(m.getKey() + "\t" + m.getValue());
intprintHashMap(String lt, HashMap map, String rt, int maxparm)
print Hash Map 
Set<String> keySetOfPaths = map.keySet();
Iterator<String> itrKeySetOfPaths = keySetOfPaths.iterator();
int maxlen = maxparm;
while (itrKeySetOfPaths.hasNext()) {
    String aKey = itrKeySetOfPaths.next();
    if (maxlen < aKey.length())
        maxlen = aKey.length();
keySetOfPaths = map.keySet();
itrKeySetOfPaths = keySetOfPaths.iterator();
while (itrKeySetOfPaths.hasNext()) {
    String aKey = itrKeySetOfPaths.next();
    String aVal = map.get(aKey);
    int gap = maxlen - aKey.length();
    System.out.print(lt + aKey);
    for (int i = 0; i < gap; i++)
        System.out.print(" ");
    System.out.println(" , " + aVal + rt);
return maxlen;
voidprintHeaders(Map> headers)
print Headers 
for (Entry<String, List<String>> h : headers.entrySet()) {
    String name = h.getKey();
    for (String value : h.getValue()) {
        if (name != null) {
            System.err.println(name + ":\t" + value);
        } else {
            System.err.println(value);
voidprintHttpMessage(String statusLine, Map headers)
print Http Message 
System.out.println(statusLine);
for (String header : headers.keySet()) {
    System.out.println(header + ": " + headers.get(header));
voidprintItems(HashMap map)
Listing of all items in a hashmap (useful for formItems

HashMap map Input to iterate over and print items 

for (Iterator iter = map.entrySet().iterator(); iter.hasNext();) {
    Map.Entry item = (Map.Entry) iter.next();
    Object value = item.getValue();
    if (value instanceof String[]) {
        String[] list = (String[]) value;
        StringBuffer out = new StringBuffer();
        out.append(item.getKey());
        out.append(" - [");
...
voidprintKeys(Map m)
Print the keys in a HashMap. 
for (Object s : m.keySet()) {
    System.out.println(s);
voidprintMap(final Map msg)
The Method printMap prints the HashMap to the console. 
for (Entry<K, V> entry : msg.entrySet()) {
    final K key = entry.getKey();
    final V value = entry.getValue();
    System.out.println("[" + key.toString() + "=" + value.toString() + "]");
voidprintMap(HashMap map)
print Map 
java.util.Iterator iterator = map.keySet().iterator();
Object key = null;
Object obj = null;
while (iterator.hasNext()) {
    key = iterator.next();
    obj = map.get(key);
    System.out.println("key:" + key + " value:" + obj);
voidprintMap(Map map)
print Map 
Iterator itr = map.keySet().iterator();
System.out.println("-----Printing Map-----");
while (itr.hasNext()) {
    Object obj = itr.next();
    System.out.println(obj + " : " + map.get(obj));
System.out.println("-----End Of Map-----");
