loop trough a 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: 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: how to iterate hashmap java

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

Example 4: java loop hashmap

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