Java – sort 2D arrays by 2D

I need to classify the goods according to the price

The price of each item is stored in a JSON array

I created a two-dimensional array to store names and prices

Like this

    String [][] priceArray = new String [itemArray.length()] [2];

    for(int i = 0; i < itemArray.length(); i++)
    {
        //put the item name in the first dimension
        priceArray[i][0] = itemArray.getJSONObject(i).getString("name");

        //put the item price in the second dimension        
        priceArray[i][1] = itemArray.getJSONObject(i).getString("baseprice");       
    }

    //DEBUG TO SEE THE RESULTS
    for(int i = 0; i < priceArray.length; i++)
    {
        Log.i("Item name : Item Price", priceArray[i][0] + " : " + priceArray[i][1]);               
    }

This works... But how can I sort the array at the price of the second dimension?

Is this even the best way?

resolvent:

Better method: use OO programming. First, create a class item containing name and price:

class Item {
    String name;
    BigDecimal price;

    public String toString() { return "ITEM: {name:" + name + ", price: " + price + "}" }
}

Then create a list of items instead of a 2D array:

List<Item> items = new ArrayList<Item>();

for(int i = 0; i < itemArray.length(); i++)
{
    Item item = new Item();
    item.name = itemArray.getJSONObject(i).getString("name");
    item.price = new BigDecimal(itemArray.getJSONObject(i).getString("baseprice"));
    items.add(item);
}

Finally, if you need, you can order by name:

// Sort by name
Collections.sort(items, new Comparator<Item>() {

    @Override
    public int compare(Item o1, Item o2) {
        return o1.name.compareTo(o2.name);
    }

});

// at this point, items will be ordered by name

Or if you want to order at a price:

// Sort by price
Collections.sort(items, new Comparator<Item>() {

    @Override
    public int compare(Item o1, Item o2) {
        return o1.price.compareTo(o2.price);
    }
});

// at this point, items will be ordered by price

Of course, I missed some small problems, such as using getters and setters instead of directly accessing item fields, but the purpose is to show this idea
