for some reason in the list object when i try to insert the code into a linked list it inserts the characters backwards instead of forwards. I have to input characters from a user created string individually into a linked list. the linked list cannot change because the teacher requires me to use the specified code in my textbook. i would appreciate if you would explain the problem and solution in words and not code. the code is in Java is there a way to get this program to output correctly? OUTPUT please enter a string. coppermakerimprint List (first -->last): tnirpmirekamreppoc MAIN FUNCTION import java.util.Scanner; /** * Write a description of class test here. * * @author (your name) * @version (a version number or a date) */ public class test { // instance variables - replace the example below with your own public static void main(String[] args) { Scanner input = new Scanner(System.in); linkedList list = new linkedList(); char character; System.out.println("please enter a string."); String inString = input.nextLine(); for(int i = 0; i < inString.length(); i++) { character = inString.charAt(i); list.insertFirst(character); } list.displayList(); } } LINKED LIST OBJECT /** * Write a description of class linkedList here. * * @author (your name) * @version (a version number or a date) */ public class linkedList { private link first; public linkedList() { first = null; } public boolean isEmpty() { return (first==null); } public void insertFirst(char id) { link newLink = new link(id); newLink.next = first; first = newLink; } public link deleteFirst() { link temp = first; first = first.next; return temp; } public void displayList() { System.out.print("List (first -->last): "); link current = first; while(current != null) { current.displayLink(); current = current.next; } /** * Write a description of class link here. * * @author (your name) * @version (a version number or a date) */ public class link { public char dData; public link next; public link(char dd) { dData = dd; } public void displayLink() { System.out.print(dData); } } System.out.println(""); } } LINK OBJECT
