      • integer

        public static Integer integer​(int x)
        Integer objects are immutable so share all Integers with the same value up to some max size. Use an array as a perfect hash. Return shared object for 0..INTEGER_POOL_MAX_VALUE or a new Integer object with x in it.
      • replace

        public static String replace​(String src,
                                     String replacee,
                                     String replacer)
        Given a source string, src, a string to replace, replacee, and a string to replace with, replacer, return a new string w/ the replacing done. You can use replacer==null to remove replacee from the string. This should be faster than Java's String.replaceAll as that one uses regex (I only want to play with strings anyway).
