Random actions in JAVA -

i'm writing first own chess game in java. code works 2 players, manually playing keyboard, , expand player against computer game.

my problem is, i've never dealt random actions. method moving piece on board, needs recieve 4 inputs: 2 ints piece location, , 2 ints destination on board.

choosing wrong inputs ok since movepiece method checks if ints not out of board's bounds, reach piece of current player's color, there's piece in coordination , not empty, etc.

but how these 4 ints randomly? , how create them closest possible "real" inputs (so dont spend alot of time disqualifying bad inputs) ?

thanks alot :d

java provides @ to the lowest degree 2 options generate random values:

http://docs.oracle.com/javase/6/docs/api/java/util/random.html http://docs.oracle.com/javase/6/docs/api/java/lang/math.html#random()

e.g. random int values bounded 4:

int x = new random().nextint(4); int y = (int) (math.random() * 4); system.out.println(x + " " + y); >> 2 3
