traversing through hashmap keys code example
Example 1: 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 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
}
