本文整理了Java中java.util.regex.Matcher.find()方法的一些代码示例，展示了Matcher.find()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.find()方法的具体详情如下：
包路径：java.util.regex.Matcher
类名称：Matcher
方法名：find

Matcher.find介绍

[英]Returns the next occurrence of the Pattern in the input. If a previous match was successful, the method continues the search from the first character following that match in the input. Otherwise it searches either from the region start (if one has been set), or from position 0.
[中]返回输入中模式的下一个匹配项。如果前一个匹配成功，该方法将从输入中匹配后的第一个字符继续搜索。否则，它将从区域开始（如果已设置）或从位置0进行搜索。
