Question

I have read an image in and I want to randomly set values for int x and int y but only up to the width and height of the image respectively and not below 0,0 so that they do not exceed the boundaries of the image.

Something like this:

read image //I have this already
assign random value to int x up to maxWidth of image but >= 0
assign random value to int y up to maxHeight of image but >= 0
end

Typically, almost all of the images that I am working with are approximately 424 x 424.

I am ultimately looking to end up with values such as:

int x = 325;
int y = 10;

or

int x = 424
int y = 351

or

int x = 109
int y = 230

Each time I run the code, the values for x and y will be reassigned randomly as before.

Is this possible?

You want something like:

import java.util.Random;

..stuff..

// create a random instance - you only need one of these
Random r=new Random();

..stuff..

// create a random co-ordinate within the image rectangle
int x=r.nextInt(image.getWidth());
int y=r.nextInt(image.getHeight());
