since the next field can contain reference to any type of objectwe can assign to it reference to one of the other listnode objects for examplesuppose we assign to the next field of object aa next which results in object being linked to object bas shown herea and finallywe can link object to object cb next resulting in chain of objectsas illustrated herea we can remove the two external references and by assigning none to eachas shown herea the result is linked list structure the two objects previously pointed to by and are still accessible via for examplesuppose we wanted to print the values of the three objects we can access the other two objects through the next field of the first objectprinta data printa next data printa next next data linked structure contains collection of objects called nodeseach of which contains data and at least one reference or link to another node linked list is linked structure in which the nodes are connected in sequence to form linear
