命名捕获组Java正则表达式
命名捕获组允许您按名称引用组。从SE7开始，Java开始支持捕获的组。
示例
import java.util.Scanner;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class ReplaceAll{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter input text: ");
String input = sc.nextLine();
String regex = "(?<globalCode>[\\d]{2})-(?<nationalCode>[\\d]{5})-(?<number>[\\d]{6})";
//创建一个模式对象
Pattern pattern = Pattern.compile(regex);
//匹配字符串中的已编译模式
Matcher matcher = pattern.matcher(input);
while (matcher.find()) {
System.out.println("Global code: "+matcher.group("globalCode"));
System.out.println("National code: "+matcher.group("nationalCode"));
System.out.println("Phone number: "+matcher.group("number"));
}
}
}输出结果
Enter input text: 91-08955-224558 Global code: 91 National code: 08955 Phone number: 224558
