Greenfoot help

[Big-D]

I am wanting to add a new actor in greenfoot at a random location

long lastAdded = System.currentTimeMillis();
    public void act() 
    {
        long curTime  = System.currentTimeMillis();  
        if (curTime >= lastAdded + 4000) //5000ms = 5s  
        {  
            MyWorld world;
            world = (MyWorld) getWorld(); 
            int x = Greenfoot.getRandomNumber(600);
            //int y = Greenfoot.getRandomNumber(450 
            world.addObject(new WoundedPerson(), x, 450);
            lastAdded  = curTime;
        }

that is my code but the commented "int y = Greenfoot.getRandomNumber(450" is supposed to be the random location on the Y-axis, I already have the X-axis, but I need to set a limit on the y axis so that 450 is the highest from the bottom of the world which is 800. Any help is appreciated

int y = 800-Greenfoot.getRandomNumber(450);

kind regards,

I need to set a limit on the y axis so that 450 is the highest from the bottom of the world which is 800.

So would that be 0-450, or 450-800? Depending on the implementation of getRandomNumber in Greenfoot, you might have to do some subtraction if it's the latter case.

world.addObject(new WoundedPerson(), x, 450);

This probably will need changed too, right?
