A lottery offers 4 different lottery games play

A lottery offers 4 different lottery games play: 3-numbers, 4-numbers, 5-numbers and 5-numbers + 1 lotteries. Each game has independent numbers. Make an application that randomly picks numbers for all four games and displays the generated numbers in the GUI. Declare a method that generates a random number based on a range given, and returns the random number as a String. The games are played as follows:
A) 3 number lotteries require players to choose 3 numbers in the range 0-9.
B) 4 number lotteries require players to choose 4 numbers in the range 0-9.
C) 5 number lotteries require players to choose 5 numbers in the range 1-39.
