A lottery commission offers four different lottery games to play: Three-number, Four-number, Five-number and Five-number + 1 lotteries. Each game has independent numbers. Develop an application that randomly picks numbers for all four games and displays the generated numbers in a 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. Three-number lotteries require players to choose three numbers in the range 0-9.

b. Four-number lotteries require players to choose four numbers in the range 0-9.

c. Five-number lotteries require players to choose five numbers in the range 1-39.

d. Five-number + 1 lotteries require players to choose five numbers in the range 1-49 and an additional number in the range 1-42.
