Create a Java program that asks the user to enter three (3) first names then display the following:

  1. All the possible two-name combinations (Ask the user to select a name by entering 1 to 6.)
  2. The initials of the chosen combined name (Ex. John Ryan = JR)
  3. Suggested username based on the combined name (The name will be in small letters and the space will be changed to underscore. Ex. John Ryan = john_ryan)
Sample output:

Enter three first names:
Mark
Ryan
John

Possible names are:
1 - Mark Ryan
2 - Mark John
3 - Ryan Mark
4 - Ryan John
5 - John Mark
6 - John Ryan
Enter 1-6 to select a name: 6
The initials for John Ryan is JR.
Suggested username: john_ryan
