question: public void shuffle ( ) { Random r = new Random ( ) ; int num = count ; while ( num > 1 ) { int value = r . nextInt ( num ) ; num -- ; float temp = data [ num ] ; data [ num ] = data [ value ] ; data [ value ] = temp ; } }
target:  Randomize the order of the list elements. Note that this does not obey the randomSeed() function in PApplet.
