How do I create a String[2][20], with only 10 items

[LCounter]

I am working on a java class, and have been asked to create an inventory object of String[2][20] and fill it with only 10 things.

The only way I can think to do this, is as follows, but, is there a better way?

private String[][] inventory = {
{"flashlight","0"},
{"knife","0"},
{"Swiss army knife", "0"},
{"camera", "0"},
{"notebook", "0"},
{"lighter", "0"},
{"lunchbox", "0"},
{"jacket", "0"},
{"cell phone", "0"},
{"mp3 player", "0"},
{"",""},
{"",""},
{"",""},
{"",""},
{"",""},
{"",""},
{"",""},
{"",""},
{"",""},
{"",""}
};

Shouldn't that be [20][2]?

Do you have an Inventory class? I'd do something like this

class Inventory {
    private final int MAX = 20;
    private String[][] inventory = new String[MAX][2];
    private int items = 0;

    public void addItem(String description, String quantity) {
        if(items < MAX) {
            inventory[items][0] = description;
            inventory[items][1] = quantity;
            items++;
        } else {
            System.out.println("Inventory is full");
        }
    }
}

Alternatively you could have the method return boolean to reflect if the item was added or not.
