Converting 3 dimensional array to 1 dimensional array

private static int[][][] pieces = 
		{
			{
				{
					1, 1, 1, 1, 1, 1, 1, 1
				},{
					1, 1, 1, 1, 1, 1, 1, 1
				},{
					1, 1, 1, 1, 1, 1, 1, 1
				},{
					1, 1, 1, 1, 1, 1, 1, 1
				}
			},{
				{
					
				}
			},{
				{
					
				}
			},{
				{
					
				}
			}
		};//continues on for size pieces[7][4][8]
	
	public static void main(String [] args){
		for(int x = 0; x < pieces.length; x++){
			for(int y = 0; y < pieces[x].length; y++){
				int[] tmp = pieces[x][y];
				int[] xs = {tmp[0], tmp[1], tmp[2], tmp[3]};
				int[] ys = {tmp[4], tmp[5], tmp[6], tmp[7]};
				System.out.println("pieces["+x+"]["+y+"] = "+Arrays.toString(xs)+Arrays.toString(ys));
			}
		}
	}

Is there any possible way to condense this three dimensional array into a two dimensional, or better yet, one dimensional array? When I try to run this on my Android phone, Eclipse does not generate the class/tex files. I'll be honest, I have no idea why this error came up, because I have used three dimensional arrays before, but here it is:

Yes, define a mapping from x,y,z to i
It might help if you took a piece of paper and wrote out a small 3 dim array with the x,y,z indexes for each element and then go back and assign it the i index of a single dim array. There should be some pattern here that you can use to write some loops to do the conversion.

for int x = 0 x < dimension1
for int y = 0 y < dimension2
for int z = 0 z < dimension3
newarray[z + (x * z) + (x * y * z)] = 3darray[x][y][z]
next everything

Should do the trick. I'm pretty tired writing this so you might not want to take my word for it.
