Icollections lite vs collections code#

Let us see the hierarchy of Collection framework. The java.util package contains all the classes and interfaces for the Collection framework. There are many methods declared in the Collection interface. It is used to insert an element in this collection. It is used to insert the specified collection elements in the invoking collection. It is used to delete all the elements of the specified collection from the invoking collection.ĭefault boolean removeIf(Predicate filter) It is used to delete an element from the collection. It is used to delete all the elements of the collection that satisfy the specified predicate. It is used to delete all the elements of invoking collection except the specified collection. It returns the total number of elements in the collection. It removes the total number of elements from the collection. It is used to search the specified collection in the collection. Here, the runtime type of the returned array is that of the specified array. It returns a possibly parallel Stream with the collection as its source. It returns a sequential Stream with the collection as its source. It generates a Spliterator over the specified elements in the collection.

It returns the hash code number of the collection. Iterator interface Iterator interface provides the facility of iterating the elements in a forward direction only. There are only three methods in the Iterator interface.

It returns true if the iterator has more elements otherwise it returns false.

It returns the element and moves the cursor pointer to the next element. It removes the last elements returned by the iterator. Interface extends the Iterable interface and therefore all the subclasses of Collection The Iterable interface is the root interface for all the collection classes. Interface also implement the Iterable interface. #ICOLLECTIONS LITE VS COLLECTIONS CODE#.
