用于正则表达式匹配的Groovy语法

import java.util.regex.Pattern
import java.util.regex.Matcher

String text = "The phone number is 123-456-7890."
Pattern pattern = Pattern.compile("(\\d{3})-(\\d{3})-(\\d{4})")
Matcher matcher = pattern.matcher(text)

if (matcher.find()) {
    String areaCode = matcher.group(1)
    String prefix = matcher.group(2)
    String lineNumber = matcher.group(3)

    println("Area code: $areaCode, Prefix: $prefix, Line number: $lineNumber")
}
