Question

[Java] Please fix my wordsEndingIn method. You have to use Arrays.copyOf(). You can't use anything like List or clone().

Implement these methods:

public static int min(int[] list) Gets the minimum value in the array. You can assume the array has at least one element

public static int min(ArrayList<Integer> list) Gets the minimum value in the ArrayList as an int. You can assume the ArrayList contains at least one element

public static ArrayList<String> wordsEndingIn(ArrayList<String> list, String letter) Gets an ArrayList of all the words in the given ArrayList that contain the given letter. The comparison is case-insensitive. 'A' and 'a' are counted as the same letter

public static String[] wordsEndingIn(String[] list, String letter) Gets an array of all the words in the given array that contain the given letter. The comparison is case-insensitive. 'A' and 'a' are counted as the same letter. You will need to use Arrays.copyOf() to return an array that contains just the words ending in the letter

[Here's my code and the last method is the problem I'm in]

import java.util.ArrayList;
import java.util.Arrays;

/**
* Static methods working with arrays and arraylists
*/
public class StuffAndThings
{
   /**
   * Get the minimum number in the array
   * @param list an array to work with
   * @return min minimum number in the array
   */
   public static int min(int[] list)
   {
       int min = list[0];
       for(int i = 0; i < list.length; i++)
       {
           if(min > list[i])
           {
               min = list[i];
           }
       }
       return min;
   }
   public static int min(ArrayList<Integer> list)
   {
       int min = list.get(0);
       for(int i = 0; i < list.size(); i++)
       {
           if(min > list.get(i))
           {
               min = list.get(i);
           }
       }
       return min;
   }
   public static ArrayList<String> wordsEndingIn(ArrayList<String> list, String letter)
   {
       ArrayList<String> endsWith = new ArrayList<String>();
       for(int i = 0; i < list.size(); i++)
       {
           String check = list.get(i).toLowerCase();
           if(check.contains(letter.toLowerCase()))
           {
               endsWith.add(list.get(i));
           }
       }
       return endsWith;
   }
  
   public static String[] wordsEndingIn(String[] list, String letter)
   {
       String[] str = new String[list.length];
       int count = 0;
       for(int i = 0; i < list.length; i++)
       {
           if(!list[i].endsWith(letter))
           {
               str[i] = str[i - 1];
           }
           else
           {
               str[i] = list[i];
           }
           count++;
       }
       String[] copy = Arrays.copyOf(str, count);
       return copy;

   }
}
