In java we will need to create a method that takes the array {1,2,3,4,5} and returns the head reference to a linkedList. We will also need to display the linked list in out main method.

Expert Solution

Code:

public class LinkedListDisplay {

    public static void main(String[] args) {

        LinkedListDisplay listDisplay = new LinkedListDisplay();
        Node head = listDisplay
            .generateLinkedList(new int[]
            {
                1, 2, 3, 4, 5
            });

        // display the list.
        Node temp = head;
        while (temp != null) {

            System.out.print(temp.item + " ");
            temp = temp.next;

        }

        System.out.println();
    }

    private Node generateLinkedList(int[] elements) {

        Node head = new Node(elements[0]);
        Node temp = head;

        for (int i = 1; i < elements.length; ++i) {
            Node newNode = new Node(elements[i]);
            temp.next = newNode;
            temp = newNode;
        }

        return head;

    }

    class Node {

        int item;
        Node next;

        Node(int item) {
            this.item = item;
        }
    }

}

Create a Java method findLongestPalindrome that takes a Scanner scn as its parameter and returns a String. It returns the longest token from scn that is a palindrome (if one exists) or the empty string (otherwise). (Implementation note: Use the built in isPalindrome method. This method calls for an optimization loop.) Where the isPalindrome Method takes a String s as a parameter and returns a boolean. It returns true if s reads the same forwards and backwards, i.e., is a...

IN JAVA Write a program with a method that returns an array. The method should accept as input a comma-delimited string with three values from a user. The array should store each value in a different element. Use Try..Catch error handling and print any failure messages, or print success from within method if the execution is successful (see Chapter 13 in the text). Call the method from the main method of the program to demonstrate its functionality by looping through...

IN JAVA A recursive method that takes a String as its argument and returns a list of Strings which includes all anagrams of the String. This method will contain a loop that generates each possible substring consisting of all but one character in the input String, ie the substring that omits the first letter, then the substring that omits the second letter, etc. Within the loop, the method calls itself recursively for each substring. For each String in the list...
