Hi, I'm working on an assignment for programming class where we're supposed to create a method that takes the contents from a text file (one giant string) and stores them piece by piece in a linked list. I'm a little stuck and not sure where to go from here, or if I'm on the right track...
import java.util.*; import java.io.File; import java.io.FileNotFoundException; public class LinkedLists { // instance variables - not sure if I should use these? // private String file; // private LinkedList<String> list; /** * A method to read the items from a file and convert them to a list. * @param fileName the file to be read * @return readItems a linked list containing read items. */ public static LinkedList<String> readItems(String fileName) throws FileNotFoundException { File input = new File(fileName); Scanner in = new Scanner(input); String file = ""; // Copy the contents from the file to a String while (in.hasNext()) { file = in.next(); } // Create the list LinkedList<String> list = new LinkedList<String>(); ListIterator<String> iter = list.listIterator(); // Copy the String contents to the Linked List while (iter.hasNext()) { for (int i=0; i<file.length(); i++) { file = in.next(); list.add(file); } } return list; } }
There is also a tester class which is supposed to create a linked list from the text file and print the list.
import java.io.File; import java.util.Scanner; public class LinkedListTest { public static void main(String[] args) { File input1 = new File("input1.txt"); Scanner in = new Scanner(input1); String s = in.next(); System.out.print(readItems(s)); } }
I'm not sure how to implement my readItems method into this main method. Should I convert my text file to a String in the main method too? So confused...
