Thread: How to use for loop for movement of points in a picture display?

This is my code so far.

It is a picture displaying an alien and a house. My assignment was to randomly generates 20 stars onto the screen, and it works well. The second part of the assignment is to make the alien spaceship move from one integer to the next depending on what the user enters, however I am having trouble understanding the process of how to do this. I know I need to create a forloop for the movement of the ship, but I don't know how to get it to move to where the user enters. If you can help me please do, (if you feel like doing it for me and then explaining it, you could do that as well to save my butt ).

I HAVE STARTED THE SECOND PART OF THE ASSIGNMENT AT THE TOP HOWEVER I HAVE COMMENTED IT SO THAT THE STARS CAN RUN PROPERLY.

//c.println ("Please enter two numbers.");
//c.println ("\nThe Alien controlling the spaceship will then fly the ship between both of the \nintegers that you entered.");
 
        //x = c.readInt ();
        //y = c.readInt ();
       // c.clear();
