Title: Bingo Card

Description:
Create a BingoCard application that displays a traditional bingo card with five columns of five unique numbers.

  • Column N has four numbers ranging from 31 through 45 and a Free Space in the middle of the column
  • Column G has numbers ranging from 46 through 60

Format() Method
The format() method can be used in place of the print() or println() methods to control the way output is displayed. The format() method arguments include a format string and an argument list. The format string contains specifiers that indicate how the corresponding strings in the argument list should be displayed. The following code demonstrates the format() method:

System.out.format("%-10s %8s %8s", "Team", "Wins", "Losses\n");
System.out.format("%-10s %8s %8s", "Jaguars", "10", "5\n");
System.out.format("%-10s %8s %8s", "Cheetahs", "14", "1\n");
System.out.format("%-10s %8s %8s", "Panthers", "8", "7\n");
