I'm trying to make a class where I put a key and value into the put method which puts the key in the k string array and value into the v string array, however it is not being saved in the array when I do get or display.
For example: put(dan,30) get(dan) returns null
display returns null null 10 times. Anyone know whats wrong?

public class Memory 
    {
        final int INITIAL_CAPACITY = 10;
       String[] k = new String[INITIAL_CAPACITY];
       String[] v = new String[INITIAL_CAPACITY];
       int count = 0;

       public Memory()
       {
          count = 0;
       }
       public int size()
       {
          return count;
       }
       public void put(String key, String value)
       {
            int a = 0;
            boolean found = false;
            for (int i = 0; i < k.length; i++)
            {
                //System.out.println("key is " + key.equals(k[i]));
                if (key.equalsIgnoreCase(k[i]))
                {
                    v[i] = value;
                    found = true;
                }
                if (found)
                    break;
                a++;
            }
            //System.out.println(a == k.length);
            if (a == k.length);
            {
              k[count] = key;
              v[count] = value;
            //System.out.println(k[count] + " " + v[count]);
              count++;          
            //System.out.println(count);
            }

       }
       public String get(String key)
       {
          String output = "a";
          for(int i = 0; i < k.length; i++)
          {
             if(!key.equalsIgnoreCase(k[i]))
             {
                output = null;
             }
             else
             {   
                output = v[i]; 
                return output;
             }  
          }
          return output;
       }
       public void clear()
       {
            for (int i = 0; i < k.length; i++)
            {
                k[i] = null;
                v[i] = null;
            }
          count = 0;
       }

        public void display()
        {
            for (int i = 0; i < k.length; i++)
            {
                System.out.println(k[i] + " " + v[i]);
            }
        }
    }
