Vending Machine class for my AP Programming class

[liquidsystem]

I've just been working on this little class that our teacher wanted us to write. We were set with the task of creating our own class, with different constructors, getters, setters, etc... I decided I'd share it here for constructive criticism.

package vending_machine;

import java.util.Arrays;



public class VendingMachine {
	
	public int i=0;
	public int k=0;
	String[][] items;
	double[][] price;
	double moneyEntered = 0.00;
	
	VendingMachine()
	{
		items = new String[2][2];
			//Set up each column in the 0th (technically 1st in real life) row
			items[0][0] = "Cool Ranch Doritos";
			items[0][1] = "Sour Cream & Onion Lays";
			
			//Set up each column in the 1st (technically 2nd in real life) row
			items[1][0] = "Extremely Unhealthy Food";
			items[1][1] = "Totally Radical Healthy Food That's Extremely Small";
			
		//End of items
		price = new double[2][2];
			//Set up price for items in the 1st row
			price[0][0] = 2.00;
			price[0][1] = 2.00;
			
			//Set up price for items in the 2nd row
			price[1][0] = 4.00;
			price[1][1] = 4.00;
		//End of price
		moneyEntered = 0.00;
	}
	
	VendingMachine(int NUM_OF_ROWS, int NUM_OF_COLUMNS)
	{
		items = new String[NUM_OF_ROWS][NUM_OF_COLUMNS];
			//Item defining done here
		
		//End of items
		price = new double[NUM_OF_ROWS][NUM_OF_COLUMNS];
			//Pricing for each item done here
		
		//End of price
		moneyEntered = 0.00;
	}
	
	
	//Setters
	void addOrChangeItem(int row, int column, String itemName, double itemPrice)
	{
		if(items[row][column] == null)
		{
			System.out.println("This element appears to be empty... Continuing");
			items[row][column] = itemName;
			price[row][column] = itemPrice;
			System.out.println("New item added at "+row+","+column+" with the price of: $"+itemPrice);
			
		}
		else
		{
			System.out.println("Replacing " + items[row][column] + " (cost: $" + price[row][column] + ")" + " with " + itemName + " (cost: $"
					+ itemPrice + ")");
			items[row][column] = itemName;
			price[row][column] = itemPrice;
		}
		
	}
	
	void changePrice(int row, int column, double itemPrice)
	{
		if(items[row][column] != null)
		{
			System.out.println("Changing the price of " + items[row][column] + " to $" + itemPrice);
			price[row][column] = itemPrice;
		}
	}
	
	void enterMoney(double m)
	{
		moneyEntered = m;
	}
	
	void chooseFood(int row, int column)
	{
		if(moneyEntered >= price[row][column])
		{
			System.out.println("You chose " + items[row][column] + " which has a price of $" + price[row][column]);
			moneyEntered-= price[row][column];
			System.out.println("Enjoy!");
		}
		else if (moneyEntered < price[row][column])
		{
			System.out.println("You don't have enough money for this! The price of this item is " + price[row][column]
					+ " Current money in the machine: $" + moneyEntered);
		}
	}
	
	//Getters
	void getFoodsAndPrices()
	{
		for(i = 0; i < 2; i++)
		{
			for(k = 0; k < 2; k++)
			{
				System.out.println("Price of " + items[i][k] + " is: " + "$" +price[i][k]);
			}
		}
	}
	
	void getMoneyEntered()
	{
		System.out.println("There is currently $" + moneyEntered + " in this machine.");
	}
	
}

EDIT: I'm also looking for more things that I should need for a vending machine (setters/getters) I feel like I covered it all though.

I don't really have any criticism at all, this is very nice, organised coding. Nice job.

[abuckau907]

VendingMachine(int NUM_OF_ROWS, int NUM_OF_COLUMNS)
{
...
}

//Getters
void getFoodsAndPrices()
{
for(i = 0; i < 2; i++)
{
...
}
}

Edit.
Noticed post was really old.

If I could suggest one thing it would be to make it a gui
