Code porting nightmare: Javascript to Java

Hello again! I'm still stuck with this.

I have a Javascript code that I have to port to Java, but after doing it the results are different.

I hate to ask and bother you with my problem, specially this, which is pretty complicated.

I assume the Javascript is correct, it's the one that it was working after all...

Javascript
Input is: width=19, depth=19, height=19
Result: count=581, total_z=0, total_y=19, total_x=19, and a long map of trues and falses.

Java
Input is: width=19, depth=19, height=19
Result: count=1093, total_z=19, total_y=19, total_x=19, and a long map of trues and falses.

First of all I don't know how to properly translate the .hasOwnProperty method, I think that what I made is fairly correct.
I think that the problem is on the loops: In the .js code uses arrays and I used Lists, and I also don't know how to do that part.

Well, here is the code. I hope you can understand it!

Javascript:
function generate_dome(width, depth, height) { var x_radius = (width - 1) / 2; var y_radius = (depth - 1) / 2; var z_radius = height; var dome = {}; var radius = Math.min(x_radius, y_radius, z_radius); var solid; var count = 0; var x_ratio = x_radius / radius; var y_ratio = y_radius / radius; var z_ratio = z_radius / radius; for (var z = 0, _z = 0; z < z_radius; z++, _z++) { if (! dome.hasOwnProperty(z)) { dome[z] = {}; } for (var y = -y_radius, _y = 0; y <= y_radius; y++, _y++) { if (! dome[z].hasOwnProperty(_y)) { dome[z][_y] = {}; } for (var x = -x_radius, _x = 0; x <= x_radius; x++, _x++) { if (! dome[z][_y].hasOwnProperty(_x)) { dome[z][_y][_x] = {}; } var xP = x / x_ratio; var yP = y / y_ratio; var zP = z / z_ratio; var distance = Math.sqrt((xP * xP) + (yP * yP) + (zP * zP)); solid = (Math.abs(distance - radius) <= 0.5); count += solid; dome[z][_y][_x] = solid; } } } var _return = { 'shape':dome, 'total_x':_x, 'total_y':_y, 'total_z':_z, 'count':count } draw_shape(_return); }

Java code:
private static Map generateDome(final int width, final int depth, final int height) { final double xRadius = (double) (width - 1) / 2; final double yRadius = (double) (depth - 1) / 2; final double zRadius = (double) height; final double radius = Math.min(xRadius, Math.min(yRadius, zRadius)); boolean solid; int count = 0; final double xRatio = xRadius / radius; final double yRatio = yRadius / radius; final double zRatio = zRadius / radius; final List<List<List<Boolean>>> dome = new ArrayList<List<List<Boolean>>>(); // PRIMERA LISTA 1/2 int z = 0; int y = 0; int x = 0; for (double z2Eval = 0; z2Eval < zRadius; z2Eval++, z++) { final List l2Complete = new ArrayList<List<Boolean>>(); dome.add(l2Complete); y = 0; // SEGUNDA LISTA 2/3 for (double y2Eval = yRadius * -1; y2Eval <= yRadius; y2Eval++, y++) { final List l2SetValues = new ArrayList<List<Boolean>>(); l2Complete.add(l2SetValues); x = 0; // TERCERA LISTA 3/3 for (double x2Eval = xRadius * -1; x2Eval <= xRadius; x2Eval++, x++) { final List val2Set = new ArrayList<Boolean>(); final double xP = x2Eval / xRatio; final double yP = y2Eval / yRatio; final double zP = z2Eval / zRatio; final double distance = Math.sqrt((xP * xP) + (yP * yP) + (zP * zP)); solid = (Math.abs(distance - radius) <= 0.5); val2Set.add(solid); l2SetValues.add(val2Set); if (solid) { count += 1; } } } } final Map result = new HashMap(); result.put("shape", dome); result.put("total_x", x); result.put("total_y", y); result.put("total_z", z); result.put("count", count); return result; }

Please, help. ;_;

There is no hasOwnProperty method in Java. Nor is there a need for one. Java and JavaScript are very very different languages. A line by line port is not going to be effective.

I think you'd be better of reverse engineering rather than trying to port.
