Description

The list of methods to do Map Print are organized into topic(s).

Method

void printHash(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());

void printHash(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());

int printHashMap(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;

void printHeaders(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);

void printHttpMessage(String statusLine, Map headers)
print Http Message

System.out.println(statusLine);
for (String header : headers.keySet()) {
 System.out.println(header + ": " + headers.get(header));

void printItems(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(" - [");
...

void printKeys(Map m)
Print the keys in a HashMap.

for (Object s : m.keySet()) {
 System.out.println(s);

void printMap(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() + "]");

void printMap(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);

void printMap(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-----");
