Workbook 6.12

From the Java Bootcamp Resources, launch Workbook 6.12.

Task 1

You're feeling good about these lottery numbers.

int[] ticket = {34, 43, 45, 65, 21, 54};

Use Arrays.copyOf() to copy all the elements of ticket into ticket2. Change the third value to 54.

int[] ticket =    {34,  43,  45,  65,  21,  54};
int[] ticket2 = // 34 - 43 - 54 - 65 - 21 - 54.

Task 2

Create a function that prints the ticket numbers. Follow the steps below:

/**
 * Function name -- printTicketNumbers
 * @param ticket ( int[] )
 *
 * Inside the function:
 *   1. Use a loop to print the numbers in one line.
 *         System.out.print(ticket[i] + " ");
 *
 *   2. After the loop, print two new lines.
 *         System.out.print("\n\n");
 *
 */

Call the function for each ticket:

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.
