Is this what you're trying to do?
public static void main(String[] args){
Object [][] objArray = new Object[10][10];
for (int i=0;i<10;i++){
for (int j=0;j<10;j++){
objArray[i][j]= new Class1(i, j);
}
}
}
public class Class1{
ArrayList<Point> coordArray = new ArrayList<Point>();
Class1(int x, int y){
coordArray.add(new Point(x,y));
}
}
