A specific element in the LinkedList can be removed using the java. util. LinkedList. remove() method.
The remove method returns true if an object passed as a parameter is removed from the list. Otherwise, it returns false. The remove method returns the removed element if an index is passed. It throws IndexOutOfBoundsException if the specified index is not in range.
