# Workbook 6.13

From the `Java Bootcamp Resources`, open **`Workbook 6.13`**.

![6.13.png](https://firebasestorage.googleapis.com/v0/b/learnthepart-75aed.appspot.com/o/images%2F22a18d30-cbde-4721-bebb-c202362e306a?alt=media&token=58e5d0d3-933e-41d5-bf73-a103b1abc303)

## Task 1

Create a 2D array of `double` values that can hold **3 rows** and **5 elements** per row.

## Task 2
Populate your 2D array with values from the following table:

For the sake of exercise, do it the *long* way (indexing elements one by one).
```java
prices[x][x] = 12.99
prices[x][x] = 8.99
//....
``` 

## Task 3

Print the prices of each row using this format:

```java
    System.out.println("Baking: " + prices[0][0] + " " + prices[0][1] + " "...);
```

### Result

## Task 4

Define the array in a single line.

```java
double[][] prices = {
    {12.99, 8.99, 9.99, 10.49, 11.99},
    {0.99, 1.99, 2.49, 1.49, 2.99},
    {8.99, 7.99, 9.49, 9.99, 10.99}
};
```

## Visualizing the Runtime

After you solve this workbook, I still recommend watching the video solution on Udemy.

It will show you how to visualize the runtime using Visual Studio Code.
