Generating a random group and integer using Java

I am making a program in Java that enquires one to enter the student's name. this should randomly place the student in a house and generate a random integer - that will be part of the house.

[the image shows how the output should look (ideally), the student name is entered, they are randomly placed in a house and a random integer (limited to four digits) of is generated using the house name]

PLEASE SEE ATTACHED BELOW FOR HOW IT SHOULD LOOK.
