falling objects

int xs[100];
int ys[100];
for (int i=0; i<100; i++) {
xs[i] = random(0,200);
ys[i] = random(0,200);
}
i am trying to use this part of my code to show the effect of snow falling but it keeps giving syntax errors. is there an easier way in processing to make a falling effect - continually (when it all gets to the bottom it restarts from the top)? thanks

Your problem is that your array declaration syntax is slightly incorrect and random() returns a float value, not an integer.
solution:
// declaring array syntax
int[] xs = new int[100];
int[] ys = new int[100];
for (int i=0; i<100; i++) {
// random returns float value. You need
// to convert to int values if you want
// to store these values in an array of integers.
xs[i] = (int)(random(0,200));
ys[i] = (int)(random(0,200));
}
