Question

*****IN JAVA****

Implement a theater seating chart  as a two-dimensional array of ticket prices, like this:

{10, 10, 10, 10, 10, 10, 10, 10, 10, 10}

{10, 10, 10, 10, 10, 10, 10, 10, 10, 10}

{10, 10, 10, 10, 10, 10, 10, 10, 10, 10}

{10, 10, 20, 20, 20, 20, 20, 20, 10, 10}

{10, 10, 20, 20, 20, 20, 20, 20, 10, 10}

{10, 10, 20, 20, 20, 20, 20, 20, 10, 10}

{20, 20, 30, 30, 40, 40, 30, 30, 20, 20}

{20, 30, 30, 40, 50, 50, 40, 30, 30, 20}

{30, 40, 50, 50, 50, 50, 50, 50, 40, 30}

Write a code snippet that:

- uses a for loop to print the array with spaces between the seat prices

- prompts users to pick a row and a seat using a while loop and a sentinel to stop the loop.

- outputs the seat price to the user.
