how to iterate hashmap 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: 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 5: java loop hashmap
map.forEach((k, v) -> {
System.out.format("key: %s, value: %d%n", k, v);
});
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();
}
}
