loop hashMap java 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: how to iterate hashmap in java

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

map.forEach((k, v) -> {
    System.out.format("key: %s, value: %d%n", k, v);
});

Example 3: map interation in java

Map map = new HashMap();
Iterator entries = map.entrySet().iterator();
while (entries.hasNext()) {
    Map.Entry entry = (Map.Entry) entries.next();
    Integer key = (Integer)entry.getKey();
    Integer value = (Integer)entry.getValue();
    System.out.println("Key = " + key + ", Value = " + value);
}

Example 4: 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
    }
}

Example 5: java loop hashmap

map.forEach((k, v) -> {
    System.out.format("key: %s, value: %d%n", k, v);
});
