Split Preserve Tokens

Apache Commons Lang 3.0 is a java library with lot of utilities and reusable components. This requires the library commons-lang3-3.0.1.jar to be in classpath. The following example shows using StringUtils.splitPreserveAllTokens() API. It splits the given string into array of tokens using whitespace as a separator by preserving all tokens, including empty tokens created by adjacent separators.
