splitByWholeSeparatorPreserveAllTokens和split之间的区别

和String.split()使用最后的类Pattern进行拆分.Pattern.compile(regex).split(this , limit);StringUtils中的使用自己的方法splitWorker(String str, char separatorChar, boolean preserveAllTokens)，这是针对2.0(JDK1.4)的性能调整.What is the difference between StringUtils.splitByWholeSeparatorPreserveAllTokens() and String.split()?With splitByWholeSeparatorPreserveAllTokens, we could limit the number of parameters that are returned in an array. Is this the only difference? 解决方案 java.lang.String.split();Usage:The array returned by this method contains each substring of this string that is terminated by another substring that matches the given expression or is terminated by the end of the string.
