## Methods of the Collection Interface
| Method | Description |
|-----------------------------|-----------------------------------------------------|
| **public boolean add(E e)** | It is used to insert an element in this collection. |
| **public boolean addAll(Collection<? extends E> c)** | It is used to insert the specified collection elements in the invoking collection. |
| **public boolean remove(Object element)** | It is used to delete an element from the collection. || **public boolean removeAll(Collection<?> c)** | It is used to delete all the elements of the specified collection from the invoking collection. |
| **default boolean removeIf(Predicate<? super E> filter)** | It is used to delete all the elements of the collection that satisfy the specified predicate. |
| **public boolean retainAll(Collection<?> c)** | It is used to delete all the elements of invoking collection except the specified collection. |
| **public int size()** | It returns the total number of elements in the collection. |
| **public void clear()** | It removes the total number of elements from the collection. |
| **public boolean contains(Object element)** | It is used to search an element. |
| **public boolean containsAll(Collection<?> c)** | It is used to search the specified collection in the collection. |
| **public Iterator iterator()** | It returns an iterator. |
| **public Object[] toArray()** | It converts collection into array. |
| **public <T> T[] toArray(T[] a)** | It converts collection into array. Here, the runtime type of the returned array is that of the specified array. |
| **public boolean isEmpty()** | It checks if collection is empty. |
| **default Stream<E> parallelStream()** | It returns a possibly parallel Stream with the collection as its source. |
| **default Stream<E> stream()** | It returns a sequential Stream with the collection as its source. |
| **default Spliterator<E> spliterator()** | It generates a Spliterator over the specified elements in the collection. |
| **public boolean equals(Object element)** | It matches two collections. |
| **public int hashCode()** | It returns the hash code number of the collection. |
