Adding objects with arrays?

Hello, I'm trying to add multiple objects at once with arrays. I currently have 3 arrays, 1 for the images, and separate arrays for the coordinates. The Following code obviously doesn't work because the addObject(obstakel, xCoords, yCoords); is wrong. What is the proper way of doing this? Thanks in advance! 
public class Stad extends World
{    
    private String[] img =
    { "Gebouw1.jpg", "Gebouw2.jpg", "Gebouw3.jpg", "Gebouw4.jpg", "Gebouw5.jpg", "Gebouw6.jpg", "Gebouw7.jpg", "Gebouw8.jpg", "Gebouw9.jpg", "Gebouw10.jpg", "Gebouw11.jpg", "Gebouw12.jpg", "Gebouw13.jpg", "Gebouw14.jpg", "Gebouw15.jpg", "Gebouw16.jpg", "Gebouw17.jpg", "Gebouw18.jpg", "Gebouw19.jpg", "Gebouw20.jpg", "Gebouw21.jpg", "Gebouw22.jpg", "Gebouw23.jpg" };
     
    private String[] xCoords =
    { "799", "20", "1419", "1038", "503", "1556", "1353", "1336", "1354", "514", "661", "713", "767", "861", "240", "1354", "462", "711", "1114", "124", "367", "272", "1249" };
    
    private String[] yCoords =
    { "37", "383", "166", "352", "279", "566", "324", "370", "418", "455", "424", "825", "424", "455", "506", "598", "556", "597", "649", "784", "784", "800", "814" }; 
    
    public Stad(){       
        super(1600, 875, 1);
        PlaatsObstakels();        
    }
    
    public void PlaatsObstakels(){
        for(int i = 0; i < img.length; i++) {
            Obstakel obstakel = new Obstakel();
            addObject(obstakel, xCoords[i], yCoords[i]);
        }
    }    
}

The problem is you are trying to supply String objects as coordinates to place the objects. Remove all quotes from around your numbers in the arrays and change the type of those number arrays from 'String' to 'int'.

Doh! stupid me.. hehe thanks, it works ;) Now i need to find a way to implement the pictures along with the objects. Ill let you know when i figured it out. I think i can use Chapter 5 with the Piano scenario for that.

You should be able to use 'obstakel.setImage(img);' either before or after adding it into the world.
