Random event generator

Question

I'm in the middle of making a simple game with java and am just wanting to ask what class/method would be best for some kind of random event generator. What i'm looking for is for a pool of ten or so events to occur at random over a given time frame that won't overlap with each other (so only one event happens at a time). The time between events should also be random (3 secs, event, 5 secs, event, 1 sec, event, etc.).
Any suggestions?

Answer 1

Make the events all implement java.lang.Runnable.
Put them in an array or java.util.List<Runnable>.
Have a loop, probably in its own thread. Before the loop starts, instantiate a java.util.Random. One each run through the loop:
1) use Random.nextInt to get an index into the array or List.
2) get the Runnable object.
3) invoke run() on it.
4) use the Random to get a random number of milliseconds in whatever range you want
5) Thread.sleep for that number of milliseconds.
