Below is the File Test, then the File, and the Array file I have made. please some help...</p> <p>$</p> <pre><code>import java.util.Scanner; public class FriendsListTest { public static void main( String[] args) { FriendsList friendsList = new FriendsList(); char selection; Scanner input = new Scanner( System.in ); do { //display menu System.out.println("\n--------------"); System.out.println("Main Menu\n"); System.out.println("1. Add a friend "); System.out.println("2. Delete a friend "); System.out.println("3. Show List "); System.out.println("4. Exit"); //selection results selection = input.next().charAt(0); switch(selection){ case '1': FriendsList.AddFriends(); break; case '2': FriendsList.RemoveFriend(); break; case '3': FriendsList.DisplayArray(); break; case '4': break; default: System.out.println("Invalid Selection"); }//end Switch }while( selection != 4);//end do }//end main }//end FriendsListTest </code></pre> <p>$ $</p> <pre><code>import java.util.Scanner; import java.util.ArrayList; public class FriendsList { public static void AddFriends() { Scanner input = new Scanner( System.in ); ArrayList&lt;Friends&gt; friend = new ArrayList&lt;Friends&gt;(20); System.out.println("\n--------------"); System.out.println("Please enter Name"); String name = input.nextLine(); //reads name System.out.println("Please enter Age"); int Age = input.nextInt(); friend.add(new Friends( Age, name)); }//end AddFriends public static void RemoveFriend() { ArrayList&lt;Friends&gt; friend = new ArrayList&lt;Friends&gt;(20); Scanner input = new Scanner( System.in ); System.out.println("\n--------------"); System.out.println("Please enter Name of person you wish you remove"); String name = input.nextLine(); friend.remove(name); }//End RemoveFriend public static void DisplayArray() { ArrayList&lt;Friends&gt; friend = new ArrayList&lt;Friends&gt;(20); System.out.print(friend); }//end DisplayArray }//end class FriendsList </code></pre> <p>$ $</p> <pre><code> class Friends { private String nName; private int nAge; public Friends(int Age, String name) { nName = name; nAge = Age; } public String getName() { return nName; } public int getAge() { return nAge; } }//end class person </code></pre> <p>Ok after your suggestions I was able to get it to store data but now I have the problem of removing data. It doesn't throw any errors when removing data but the data remains. If I would repost the program if you with the edits that I have done.</p>
