voidprintMap(Map mp)
print Map 
Iterator it = mp.entrySet().iterator();
while (it.hasNext()) {
    Map.Entry pairs = (Map.Entry) it.next();
    it.remove();
StringprintMap(Map theMap)
print Map 
StringBuilder theBuf = new StringBuilder();
for (Map.Entry<? extends K, ? extends V> entry : theMap.entrySet()) {
    theBuf.append(entry.getKey());
    theBuf.append(" --> ");
    theBuf.append(entry.getValue());
    theBuf.append(System.getProperty("line.separator"));
return theBuf.toString();
...
voidprintMap(Map mp)
print Map 
Iterator<?> it = mp.entrySet().iterator();
while (it.hasNext()) {
    Entry<?, ?> pairs = (Entry<?, ?>) it.next();
    Object obj = pairs.getValue();
    if (obj instanceof int[]) {
        int[] seq = (int[]) obj;
        System.out.print(pairs.getKey() + " =");
        for (int i = 0; i < seq.length; ++i) {
...
voidprintMap(Map map)
print Map 
if (map == null) {
    System.out.println("NULL");
    return;
if (map.size() == 0) {
    System.out.println("EMPTY");
    return;
for (Map.Entry<K, V> entry : map.entrySet()) {
    System.out.println(entry.getKey() + " = " + entry.getValue());
voidprintMap(Map map)
print Map 
Set<Map.Entry<K, V>> resultsEntry = map.entrySet();
Iterator<Map.Entry<K, V>> iter = resultsEntry.iterator();
while (iter.hasNext()) {
    Map.Entry<K, V> result = iter.next();
    System.out.println(result.getKey() + " = " + result.getValue());
voidprintMap(Map map)
To print given maps content with System.out.println, both keys and values are printed. 
Set<Entry<Object, Object>> s = map.entrySet();
Iterator<Entry<Object, Object>> it = s.iterator();
while (it.hasNext()) {
    Map.Entry entry = it.next();
    Object key = entry.getKey();
    Object value = entry.getValue();
    System.out.println(key.toString() + " => " + value.toString());
voidprintMap(Map map)
print Map 
for (Object key : map.keySet()) {
    println("key: " + key + " value: " + map.get(key));
voidprintMap(Map map)
print Map 
for (Map.Entry<String, Integer> entry : map.entrySet()) {
    System.out.println("[Key] : " + entry.getKey() + " [Value] : " + entry.getValue());
StringBuilderprintMap(Map map)
print Map 
StringBuilder strBuilder = new StringBuilder();
Set<String> keySet = map.keySet();
List<String> keys = new ArrayList<>(keySet);
strBuilder.append("{");
for (String key : keys) {
    strBuilder.append("\"" + key + "\":");
    strBuilder.append(map.get(key).toString());
    if (!key.equals(keys.get(keys.size() - 1))) {
...
voidprintMap(Map map, int depth)
Prints the map. 
String log = "Parent";
if (depth > 0) {
    log = "Children";
StringBuilder str = new StringBuilder();
int loop = depth;
while (loop > 0) {
    str.append('\t');
