What's wrog with my game's inventory code?

[AaronLLF]

OK, so I'm making a video game and I have a simple inventory code. This is the inventory class:

public class Inventory {
	static int slot[] = new int[17];
	static boolean[] taken = new boolean[17];
	static int item[] = new int[17];
	static int count[] = new int[17];
	public static void addToSlot(int i, int j)
	{
		
		String itemNumString = Integer.toString(i);
			for(int k = 1;k<=16;)
			{
				String slotNumString = Integer.toString(k);
				if(taken[k] == true)
				{
					System.out.println("Slot ".concat(slotNumString) + " is already taken");
					k++;

				} else {
					System.out.println("Item of the ID ".concat(itemNumString) + " has been added to the slot of the ID ".concat(slotNumString));
					item[k] = i;
					count[k]++;
					taken[k] = true;
				}
			}
	}
}

What it does is check every slot, and if it's taken continue the loop, if not stop the loop & add the item to that slot.

But the console outputs:

Item of the ID 1 has been added to the slot of the ID 1
Slot 1 is already taken
Item of the ID 1 has been added to the slot of the ID 2
Slot 2 is already taken
Item of the ID 1 has been added to the slot of the ID 3
Slot 3 is already taken
Item of the ID 1 has been added to the slot of the ID 4
Slot 4 is already taken
Item of the ID 1 has been added to the slot of the ID 5
Slot 5 is already taken
Item of the ID 1 has been added to the slot of the ID 6

Slot 15 is already taken
