Remove Elements from a HashSet while Iterating [duplicate]
...
You can manually iterate over the elements of the set:
Iterator<Integer> iterator = set.iterator();
while (iterator.hasNext()) {
Integer element = iterator.next();
if (element % 2 == 0) {
iterator.remove();
}

Drawing Isometric game worlds
...loop with fairly straight forward logic that works consistently throughout all tiles.
Disadvantage:
One downside to that approach is that the x and y coordinates of the tiles on the map will increase in diagonal lines, which might make it more difficult to visually map the location on the screen t...

How to sort an array of integers correctly
...
By default, the sort method sorts elements alphabetically. To sort numerically just add a new method which handles numeric sorts (sortNumber, shown below) -
var numArray = [140000, 104, 99];
numArray.sort(function(a, b) {
return a - b;
});
console.log(numArray);
