We're supposed to simulate a game of clue in our AP Comp Sci class using arrays/lists.

What would be an efficient way of assigning/generating values to randomly select?

We use the Math class and usually something like math.random but need more help and guidance on this thanks

What even is a 'game of clue' ?

CBA to read all of that sorry.
If you could give a summary of what you're supposed to make with this, that'd probably help

4 people in an array/list,

4 locations in an array/list,

randomly select a person , and a place

and then I just simply print out the result.

Initial idea was to assign everyone a value, generate a value, and print whatever the value was assigned to

public class Clue {
	
	private final static String[] PEOPLE = {"Tom", "FrostBug", "NormieNurd", "Moldy" };
	private final static String[] PLACES = {"Library", "House", "Place", "OtherPlace" };
	
	public static void main(String[] args) {
		String person = PEOPLE[(int)(Math.random() * PEOPLE.length)];
		String place = PLACES[(int)(Math.random() * PLACES.length)];
		
		System.out.println("Murder at " + place + " by " + person);
	}
}

Like that?

lol

randomly select an index from 'people' and 'location', remove the objects from the list, print out result, continue till empty, profit

yea, i just added..
String person1 = PEOPLE[(int)(Math.random() * PEOPLE.length)];

and added in the print to make a murdered, and not just a murderer, thanks : D

If you haven't figured out arrays work in Java, then I know you haven't a clue what 

private final static

means. You should probably tweak your code, unless you want to be that kid who hands in an A+ work, but who can't explain any of it.

i know final when regarding declaring variables, any different there? if so, then I could learn. Didn't even spot that part of the code till you pointed it out.
