   private int size;
   private Node<K, V>[] table;
    
   public SimpleHashMap(int capacity) {
      table = (Node<K, V>[]) new Node[capacity];
   }
    
   public SimpleHashMap() {
      this(16);
   }
    
   private int index(K key) {
        // färdig att använda
   }

   private Node<k, V> findNode(int index, K key) {
       // färdig att använda
   }
   
   // Övriga metoder i klassen put, get ...
    
   private static class Node<K, V> {
      private K key;
      private V value;
      private Node<k, V> next;

      private Node(K key, V value) {
         this.key = key;
         this.value = value;
         this.next = null;
      }
   }
}```

Here's the class

 * Associates the specified value with the specified key in this map. If the map
 * previously contained a mapping for the key, the old value is replaced.
 */
public V put(K key, V value) {
    if(table[index(key)].key == key) {
        return table[index(key)].value = value; 
    }
    return table[index(key)].value = value; 
     
}

/**
 * Returns the value to which the specified key is mapped, or null if this map
 * contains no mapping for the key.
 */
public V get(K key) {    
    if(table[index(key)].key != key) {
        return null;
    }
    return table[index(key)].value;
}``` Here's the methods with what it is supposed to be doing, and also what I have been writing
