How to loop through existing objects?

Ok, so I have a 14x14 2d array, which is looped through, and squares are added to the world (In all positions). Each square has a different colour (colourNum is an integer inside of the class), and is set inside of the Square.class. How can I loop through all of the objects and check if they are all of the same colour?

you can get all the squares like this :
?
1
getWorld().getObjects(Square.class);
and loop trough them like this
?
1
2
3
4
5
6
int color;
for(Squere s : getWorld().getObjects(Square.class)) {
    if(color == null) color = s.color;
    if(color != s.color) return false;
}
return true;

You cannot directly set the elements of the list returned by 'getObjects' to a variable of type Square without casting the elements to type Square first. You can replace line 2 with either this:
?
1
2
3
for (Object obj : getWorld().getObjects(Square.class))
{
    Square s = (Square)obj;
or with this (I believe this also works)
?
1
for (Square s : (java.util.List<Square>)getWorld().getObjects(Square.class)) {
