在Java-Regex中,可以使用正则表达式来匹配多个组。正则表达式是一种用于匹配和操作字符串的强大工具,它可以用来检查字符串是否符合特定的模式。 在Java中,可以使用java.util.regex包中的Pattern和Matcher类来进行正则表达式的匹配。以下是一个示例代码,演示如何在Java中使用正则表达式匹配多个组: 代码语言:java 复制 impor...

还有一个特殊的组(group(0)),它总是代表整个表达式。该组不包括在 groupCount 的返回值中。 先上代码: import java.util.regex.Matcher; import java.util.regex.Pattern; public class PatternDemo { public static void main(String[] args) { // TODO Auto-generated method stub ...
