I need help with this Java program:

Write a java program Running a lottery for migacents, with a price of $4000.00:

Start with an empty bag.

Each ticket is represented by an integer, with its range being determined by the programmer.

One ticket number may be purchased multiple times.

For each ticket purchased, put an item in the bag.

Don't grab if not tickets purchased.

The odds should be determined before the sale.

The winning number should be randomly picked up in the number range announced before the sale.

Use a special number (e.g. 1) as the indication of the end of the sales.

The winners number should be announced, as well as the number of winners, and the price for each winner. If there is no winner, an announcement, which include the message the price will be roll over to next round, should also be made.
