CODE:  
 //Input: 3 automobile car manufacturer maker children kids
   //15 The automobile manufacturer recommends car seats for children if the automobile doesn't already have one.
   import java.util.Scanner;
   public class LabProgram{
   public static int findWordInWordList(String[] wordList, String wordToFind, int numInList) {
           for (int i = 0; i < numInList; i++) {
               if (wordList[i].equals(wordToFind)) {
                   return i;
               }
           }
           return -1;
       }
       public static void main(String[] args) {
           Scanner scan = new Scanner(System.in);
           String[] original_String = new String[20];
               String[] modified_String = new String[20];
           int numInList = scan.nextInt();
           for (int i = 0; i < numInList; i++) {
               original_String[i] = scan.next();
               modified_String[i] = scan.next();
           }
           int num_Of_Words = scan.nextInt();
           String[] words_To_Replace = new String[num_Of_Words];
           for (int i = 0; i < num_Of_Words; i++) {
               words_To_Replace[i] = scan.next();
           }
           int indx;
           for (int i = 0; i < num_Of_Words; i++) {
               indx = findWordInWordList(original_String, words_To_Replace[i], numInList);
               if (indx != -1)
                   words_To_Replace[i] = modified_String[indx];
           }
           for (int i = 0; i < num_Of_Words; i++)
               System.out.print(words_To_Replace[i] + " ");
           System.out.println();
       scan.close();
       }
   }
cheers i hope this helps!!!!1
