This is a very old question but this Java 8+ solution might be useful to someone:

public static String[] removeElements(String[] allElements) { return Arrays.stream(allElements) .filter(Objects::nonNull) .collect(Collectors.toArray()); } or if you, like me, are a fan of readable code and don't want static methods to get in your way, you can simplify this even further using static imports:

public static String[] removeElements(String[] allElements) { return stream(allElements).filter(Objects::nonNull).collect(toArray()); }
