Iterating Map in Java using KeySet Iterator && using EntrySet

HashMap

Set<String> keySet = loans.keySet();

Iterator<String> keySetIterator = keySet.iterator();

while (keySetIterator.hasNext()) {

   System.out.println("------------------------------------------------");

   System.out.println("Iterating Map using KeySet Iterator");

   String key = keySetIterator.next();

   System.out.println("key: " + key + " value: " + loans.get(key));

}

Output:

------------------------------------------------

Iterating Map using KeySet Iterator

key: home loan value: citibank

------------------------------------------------

Iterating Map using KeySet Iterator

key: personal loan value: Wells Fargo

Example for using EntrySet

Set<Map.Entry<String, String>> entrySet = loans.entrySet();

for (Entry entry : entrySet) {

   System.out.println("------------------------------------------------");

   System.out.println("looping HashMap in Java using EntrySet and java5 for loop");

   System.out.println("key: " + entry.getKey() + " value: " + entry.getValue());

}

Output:

------------------------------------------------

looping HashMap in Java using EntrySet and java5 for loop

key: home loan value: citibank

------------------------------------------------

looping HashMap in Java using EntrySet and java5 for loop

key: personal loan value: Wells Fargo
