字符串对象可以调用public String replaceAll(String regex, String replacement)方法返回一个字符串,该字符串是将当前字符串和参数regex指定的正则表达式匹配的子字符串用参数replacement指定的字符串替换后的字符串。(注意点:replaceAll()方法返回一个新字符串,不会改变当前字符串。) //例子一 String result = ...

3)regexp自带的测试例程,也很有参考价值。它把所有正则式及相关的字符串以及结果都放在一个单独的文件里,在$REGEXPHOME/docs/RETest.txt中。当然,这个例程的运行也要在$REGEXPHOME目录下。 cd $REGEXPHOME java org.apache.regexp.RETest 参考资料
