java iterate through hashmap code example

Example 1: java iterate through hashmap

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

Example 2: how to iterate hashmap in java

for (Map.Entry 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: java iterate through map

for (Map.Entry entry : map.entrySet()) {
    String key = entry.getKey();
    Object value = entry.getValue();
    // ...
}

Example 4: iterating over a hashmap

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

Example 5: how to iterate hashmap java

Map map = new HashMap();
for (Map.Entry entry : map.entrySet()) {
    System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());
}

Example 6: loop hash map

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
    }
}
