[Khairul Kabir]

I am using eclipse IDE and write code in java, for create column I search in google then found few source code but actually I need the column condition and I can't understand.
here my column code

columns.add(new Rectangle(WIDTH+width+columns.size()*300, HEIGHT-height-110, width, height));

columns.add(new Rectangle(WIDTH+width+(columns.size()-1)*300,0,width,HEIGHT-height-space));

Why dint you tried LIBGDX Framework, is easier to make games with java. There is an tutorial, Zombie Bird i believe, just grab on the google, LIBGDX tutorial Zombie Bird, and there is a step to step, very easy and with the coding!
I made on game based on t his tutorial you could try it as well SOS Aliens
