Why is one Scenario being constructed and another doesn't get constructed??

I have two games that i'm working on. But one Game suddenly didn't want to load and because other did load, I re-installed greenfoot (I've tried restarting the programm but it didn't load). PS: I have no syntax errors and I've compiled every actor dozens of times.

Show codes. Start with MyWorld class (or your initial World subclass).

I've just noticed that my code got resettet although i have compiled it and saved it 
public class MyWorld extends World
{
    
    /**
     * Constructor for objects of class MyWorld.
     * 
     */
    public MyWorld()
    {    
        // Create a new world with 800x800 cells with a cell size of 1x1 pixels.
        super(800, 800, 1); 
        prepare();
        
    }
    
    public void prepare()
    {
        int x = Greenfoot.getRandomNumber(600);
        int x1 = Greenfoot.getRandomNumber(600);      
        while (x == 0)
        {
            x = Greenfoot.getRandomNumber(600);
        }
        while (x <= 800)
        {
            x = Greenfoot.getRandomNumber(600);
        }
        while (x == x1)
        {
            x = Greenfoot.getRandomNumber(600);
            x1 = Greenfoot.getRandomNumber(600);
        }
        while (x1 == 0)
        {
            x1 = Greenfoot.getRandomNumber(600);
        }
        while (x1 <= 800)
        {
            x1 = Greenfoot.getRandomNumber(600);
        }
        ElonMusksCar eleonMusksCar = new ElonMusksCar();
        addObject(eleonMusksCar,400,754);
        alien aliens = new alien();
        addObject(aliens, x, 48);
        
    }         
}

Line 24 will always be true and execution will never branch out of the while loop. Same with line 37.

If you want two unequal random numbers between 0 and 599, then 
int x = Greenfoot.getRandomNumber(600);
int x1 = Greenfoot.getRandomNumber(599);
if (x1 >= x) x1++;
If not zero, as well: 
int x = 1+Greenfoot.getRandomNumber(599);
int x1 = 1+Greenfoot.getRandomNumber(598);
if (x1 >= x) x1++;

hey danpost, Thnx for your quick reply but I fixed my Problem. As other Discussion stated about this sort of topic, my problem was that i had an infinite loop in line 24 to 27: 
while (x <= 800)
        {
            x = Greenfoot.getRandomNumber(600);
        }
Where the loop asked while under 800 generate a new number. But the Number could only be under 800 because the program can only generate up to the number 600 in the line 18: 
  int x = Greenfoot.getRandomNumber(600);
so thnx for your help though and i will still change the code as you have written.
