Using 2D array to store a portion of a line

I have a .txt that contains

bananas, 1, 15
dogs, 1, 10
cats, 1, 5

Using the split(", ") method, I was able to get the first 15 in the first row in my array String[] price , but I want to store the last two numbers as well. I was thinking a 2D array in which

price[0][2] = 15,
price[1][2]=10
price[2][2] = 5

and parsing the three as a double and adding them together. I have this,

while ((linePrice = totalReader.readLine()) != null) {
    price1 = linePrice.split(", ");
    if ((line = totalReader.readLine()) != null) {
        price2 = linePrice.split(", ");
    }
    if ((line = totalReader.readLine()) != null) {
        price2 = linePrice.split(", ");
    }
}

but it accomplishes nothing because all three of the prices are just the first, 15.

You need to simply iterate over each line from text file and grab price by splitting line on , and append to price array, below pseudo code get you started

String[] prices = new String[3];
int i = 0;
while ((linePrice = totalReader.readLine()) != null) {
    String[] array = linePrice.split(", ");
    prices[i] = array[2]; // third index contain price
    i++;
}
