java - How do I make my for loop print my LinkedList Queue properly -

i writing program encode messages using repeating sequence. believe got encoding process correctly. using tostring statement before printing loop gives me correct values, when try , run loop @ end not print every element in list. example when enter "hello" "igo" instead of expected "igopt". thing can think of somehow encoded list somehow shrinking run loop, created new linkedlist print not affect encoded list, i'm not sure why isn't printing correctly.

import java.util.*;  public class encode {      public static void main(string[] args) {         encode enc = new encode();         system.out.println("please enter string decode");         scanner scan = new scanner(system.in);         string str = scan.nextline();         system.out.println("encoded: " + enc.encode(str));      }      public string encode(string toencode) {         queue key = new linkedlist(); // creates key , adds key values         queue clone = new linkedlist();         key.add(1);         key.add(2);         key.add(3);         key.add(4);         key.add(5);         linkedlist encoded = new linkedlist(); // creates list encoded         linkedlist print = new linkedlist();         print = encoded; // values         int ascii; // ascii value of character         int keyvalue; // int value of key add ascii , encode         // characters         char result; // sum of int values of character , key         string s = ""; // initializes string used return value         (int = 0; < toencode.length(); i++) {              clone = key;             char mychar = toencode.charat(i); // gets character @             ascii = (int) mychar; // converts character @ int value             if (ascii == 32) { // ignores spaces                 continue;             }              else { // if character not space                 keyvalue = (int) clone.remove();                 result = (char) (ascii + keyvalue);                 encoded.add(result);                 clone.add(keyvalue);              }          }         system.out.println(encoded.tostring()); // testing see if encoded                                                 // *remove after         // prints elements of encoded list         (int j = 0; j < encoded.size(); j++) {              s = s + print.remove(); // gets first value , concatenates                                     // string         }          return s;     }  }

that's what's happening.

your linkedlist print not protecting @ all, it's reference same list, , removals on affecting original list.

to make different list same elements, create using

    linkedlist print = new linkedlist(encoded);
