How to get the values from the Hashmap without using Iterator?

Question

Iterator iterator = map.entrySet().iterator();
while (iterator.hasNext()) 
{
    Map.Entry mapEntry = (Map.Entry) iterator.next();
System.out.println("The key is: " + mapEntry.getKey() + ",value is :" + mapEntry.getValue());

}

This is my code. Now i don't want to use Iterator to get the values. Please help me to find best solution.

Answer 1

Map<String, Object> map = .....;//Initialization here
for (String key : map.keySet()) {
    // write your code here
}

//If you are just using keys of the Map

for (Object value : map.values()) {
     // write your code here
}

//If you are just using values from your Map

for (Map.Entry<String, Object> entry : map.entrySet()) {
    String key = entry.getKey();
    Object value = entry.getValue();
    // you code here
}

//If you want both Keys and values

//All are without using Iterator of the Map
