本文提供了一个快速的Java函数，利用正则表达式计算给定字符串中的单词数量。通过创建模式匹配对象，从字符串中查找所有匹配的单词序列，并计算找到的匹配项数量。

Word Count in PeopleCode Using Regular Expressions

Here is a quick function that will calculate the word count of a string using Java Regular expressions.

Function wordcountjava(&inString as string) returns integer

   Local JavaObject &patternClass = GetJavaClass("java.util.regex.Pattern");
   Local JavaObject &pattern = &patternClass.compile("(\w+)");
   Local JavaObject &jstring = CreateJavaObject("java.lang.String", &inString);
   Local JavaObject &matches = &pattern.matcher(&jstring.subSequence(0, &jstring.length()));
   
   Local integer &i;
   
   While &matches.find()
      &i = &i + 1;
   End-While;
   return &i;
