Notes

• "n++" tells the code how many messages it's printed. Removing it makes the loop trigger infinitely, printing infinite messages.
• To make the code print 10 times, change "while (n < 5)" to "while (n < 10)".
• To make the code ask you for the number of messages, create an int variable for the number of repeats. Then, write a line of code asking for a keyboard.nextInt() to set the variable's value. Finally, change "while (n < 5)" to "while (n < repeats)".
