Question

I need to create a program that wil  prompts the user to input three numbers. This program should then output the numbers in nondescending order.

and it must include a parent and “main” class

“import” statement that will allow you to use the “JOptionPane” class

Create 3 variables that will allow your program to enter and store numeric numbers and initialize each.

Input a number from the dialog box and then check that the number is not equal to any of the other two numbers. If this condition fails then display an error message and exit the program.
