java，校验邮箱的正则

以下是Java中校验邮箱的正则表达式的示例代码：

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

public class EmailValidator {
    private static final String EMAIL_REGEX = "^[A-Za-z0-9+_.-]+@[A-Za-z0-9.-]+$";

    public static boolean validateEmail(String email) {
        Pattern pattern = Pattern.compile(EMAIL_REGEX);
        Matcher matcher = pattern.matcher(email);
        return matcher.matches();
    }

    public static void main(String[] args) {
        String email = "test@example.com";
        boolean isValid = validateEmail(email);
        System.out.println("Is email valid? " + isValid); // 输出：Is email valid? true
    }
}
