iterating over a hashmap code example

Example 1: java iterate through hashmap

for (Map.Entry<String, String> entry : yourHashMap.entrySet()) {
	System.out.println(entry.getKey() + " = " + entry.getValue());
}

Example 2: iterating over a hashmap

for(Map.Entry<String, Integer> entry : hashMap.entrySet()) {
    String key = entry.getKey();
    Integer value =  entry.getValue();
    //do something with the key and value
}

Example 3: iterate hashmap java

public static void printMap(Map mp) {
    Iterator it = mp.entrySet().iterator();
    while (it.hasNext()) {
        Map.Entry pair = (Map.Entry)it.next();
        System.out.println(pair.getKey() + " = " + pair.getValue());
        it.remove(); // avoids a ConcurrentModificationException
    }
}
