本文整理了Java中java.util.regex.Matcher.appendTail()方法的一些代码示例，展示了Matcher.appendTail()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Matcher.appendTail()方法的具体详情如下：
包路径：java.util.regex.Matcher
类名称：Matcher
方法名：appendTail

Matcher.appendTail介绍

[英]Appends the (unmatched) remainder of the input to the given StringBuffer. The method can be used in conjunction with #find() and #appendReplacement(StringBuffer,String) to walk through the input and replace all matches of the Patternwith something else.
[中]将输入的剩余部分（不匹配）追加到给定的StringBuffer。该方法可以与#find（）和#appendReplacement（StringBuffer，String）结合使用，遍历输入并用其他内容替换模式的所有匹配项。
