Implement a class named Parade using an ArrayList, which will manage instances of class Clown. Each Clown only needs to be identified by a String for their name. Always join a new Clown to the end of the Parade. Only the Clown at the head of the Parade (i.e., the first one) can leave the Parade. In addition, also write a method called isFront that takes a Clown as parameter and returns true if the passed clown is at the front of the parade otherwise returns false. Create a test application to demonstrate building a parade of three or four clowns and include your own name. Then, remove one or two, and add another one or two. Also, test the isFront method by passing different clowns to the method.
Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).
