public boolean isEmpty()
{
/* Returns "true" if the list is empty. Otherwise returns "false" */
return head == null;
}
Explanation:
The above method definition is used to returns “true” if the value of “head” is equal to “null”. Otherwise returns “false”.
Complete code:
The complete code for after implementing “isEmpty” method is given below:
Filename: “ListNode.java”
//Define "ListNode" class
public class ListNode
{
/* Refer the textbook of Listing 12.4 */
}
