This is an example of how to remove all mappings from a LinkedHashMap, that means clearing the LinkedHashMap. Removing all mappings from a LinkedHashMap implies that you should: Create a new LinkedHashMap. Populate the linkedHashMap with elements, with put(K key, V value) API method of LinkedHashMap. Invoke clear() API method of LinkedHashMap. The method removes all of the mappings from ...

In this example we shall show you how to obtain a LinkedHashMap Iterator, that is an iterator over the LinkedHashMap key value pairs. To obtain a LinkedHashMap Iterator one should perform the following steps: Create a new LinkedHashMap. Populate the linkedHashMap with elements, with put(K key, V value) API method of LinkedHashMap. Invoke entrySet() API method of LinkedHashMap. It returns ...

With this example we are going to demonstrate how to get the size of a LinkedHashMap, that is the number of key-value mappings in this LinkedHashMap. In short, to get the size of a LinkedHashMap you should: Create a new LinkedHashMap. Populate the linkedHashMap with elements, with put(K key, V value) API method of LinkedHashMap. Invoke size() API method of ...

In this example we shall show you how to get a Set view of the LinkedHashMap keys. To get a Set view of the LinkedHashMap keys one should perform the following steps: Create a new LinkedHashMap. Populate the linkedHashMap with elements, with put(K key, V value) API method of LinkedHashMap. Invoke keySet() API method of LinkedHashMap. The method returns a ...

With this example we are going to check a value existence in a LinkedHashMap. In short, to check if a value exists in a LinkedHashMap you should: Create a new LinkedHashMap. Populate the linkedHashMap with elements, with put(K key, V value) API method of LinkedHashMap. Invoke containsValue(Object value) API method of LinkedHashMap. The method returns true if this map maps ...

This is an example of how to check a key existence in a LinkedHashMap. Checking if a key exists in a LinkedHashMap implies that you should: Create a new LinkedHashMap. Populate the linkedHashMap with elements, with put(K key, V value) API method of LinkedHashMap. Invoke containsKey(Object key) API method of LinkedHashMap, with a specified key as parameter. The method returns ...

In this example we shall show you how to remove an element from a HashSet if it exists in the HashSet. To remove an element from a HashSet one should perform the following steps: Create a new HashSet. Populate the HashSet with elements, using add(E e) API method of HashSet. Invoke remove(Object o) API method of HashSet, with the element ...

With this example we are going to demonstrate how to remove all elements from a HashSet. In short, to remove all elements from a HashSet you should: Create a new HashSet. Populate the hashSet with elements, using add(E e) API method of HashSet. Invoke clear() API method of HashSet. The method removes all the elements from the set, so that ...

This is an example of how to obtain a HashSet Iterator, that is an iterator over the elements of the HashSet. Obtaining a HashSet Iterator implies that you should: Create a new HashSet. Populate the hashSet with elements, using add(E e) API method of HashSet. Invoke iterator() API method of HashSet. The method returns the Iterator over the elements in ...

In this example we shall show you how to get the HashSet size, that is the number of all the elements that the hashSet contains. To get the HashSet size one should perform the following steps: Create a new HashSet. Populate the hashSet with elements, using add(E e) API method of HashSet. Invoke size() API method of HashSet. The method ...
