A few good ways to remove space from a string.

Method 1

private static String removeSpace(String aword) {
     StringBuilder buffer = new StringBuilder();
        for (int i = 0; i < aword.length(); i++)   {
         if (aword.charAt(i) != ' ')) {
             buffer.append(aword.charAt(i));
         }
     }
     return buffer.toString();
}
