Colour/hatching not important, will be completed in post if requires further code - looking to learn how to complete this code to generate random arrangements.

Current attempts attached below

int count;
int numb = 10;
Wall walls = new Wall();
Floor floors = new Floor();
Board boards = new Board();
Block blocks = new Block();
Post posts = new Post();
Glass glasses = new Glass ();
Cage cages = new Cage();
Cord cords = new Cord();
Stairs stairs = new Stairs();
Screeen screens = new Screen();
