LibGDX How should i render a random generated map

Hello first thing first i want to say i am VERY! New to coding,game dev, and java so be nice if the fix is very easy.

I got the generater form here: http://javagamexyz.blogspot.com.au/2013/03/terrain-generation.html

Ok my ? is how should i render. Some thing like

MidpointDisplacement md = new MidpointDisplacement();
		temp = md.getMap();
		for(int row = 0; row < temp.length; row++) {
			for(int col = 0; col < temp[row].length; col++) {
			}
				
		}

But what should i use to render (what do i add the texters to?)

All help is welcomed.

Thank You
