Shuffle random string from arraylist?

Question

I have an arrayList where I have entered some strings (names). The assignment is pretty simple but I have no idea how to do it. We have to make a program that will print out a random String in the console from the list.

I've come this far:

ArrayList <String> p = new ArrayList <String> ();
Random ran = new Random ();

p.add("Petter");
p.add("Per");
p.add("Mohammed");

System.out.println(p.get(ran.next));

Try this..

Collection.shuffle(p);
System.out.println(p.get(0));

That will be unnecessarily inefficient. There is no need to shuffle entire collection when you just want to choose random element. – damgad Oct 08 '14 at 09:28
