Build a complete java program using JOptionPane that randomly generates a lottery of a three-digit number,prompts the user to enter a three-digit number, and determines whether the user wins according to the following rule:
a. if the user input matches the lottery in exact order the award is 5,000
b.if the user input matches three digits in different order, the award is 2,000
c.if any 1 or 2 digits in the user input matches the lottery the award is 5,00

Note
1 if the user keyed in less than three digits or more than 3 digits prompt an error message and urge the user to key in again the numbers.
2.use widow for input and output.

Since that's a homework assignment. And we don't do your assignment for you. Show us what you have already. And someone can offer advice on the coding.

LOL!!!! You build it and let us know how it works.

You seriously think someone here is going to do that so you don't have to?
