One way to validate a Gmail address in Java is to use regular expressions. Here is a sample code that shows how to validate a Gmail address using a regular expression:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class ValidateGmailAddress {
public static void main(String[] args) {
String email = "example@gmail.com";
// Regular expression for a Gmail address
String regex = "^[a-zA-Z0-9_+&*-]+(?:\.[a-zA-Z0-9_+&*-]+)*@(?:gmail)\.com$";
// Compile the regex
Pattern pattern = Pattern.compile(regex);
// Match the email address with the regex
Matcher matcher = pattern.matcher(email);
// Check if the email address is valid
if (matcher.matches()) {
System.out.println("Valid Gmail address");
} else {
System.out.println("Invalid Gmail address");
}
}
}

In this code, we have defined a regular expression that matches a Gmail address. The regex checks for the pattern of letters, digits, and special characters before the @ symbol, followed by the domain gmail.com.
We then compile the regex using the Pattern class and create a Matcher object to match the email address with the regex pattern. If the email address matches the pattern, it is considered a valid Gmail address.
You can customize the regex pattern based on your specific needs and requirements for validating a Gmail address.
