Send SMS Alert to saved contact in Java

Steps to Send SMS Alerts Using Java

In this article, we'll explore how to send SMS alerts to saved contacts using Java. We will guide you on how to Send SMS alerts using Java to saved or unsaved Contacts. Following are the steps to do so ?

• Setting up an account with the SMS provider.
• Adding provider Java library to your project.
• Writing Java code to send the SMS.

Let's elaborate on the above steps.

Setting up Account

First of all, we need to set up an account in any of the messaging APIs such as Twilio.

• Create a Twilio Account Sign up for an account.
• Get credentials once you have an account you will have an Account SID and AUTH TOKEN. You will need this to authenticate your request.

Adding Java Library to Your Project

To interact with Twilio you need to include the Twilio Java Library in your project. For this purpose, you need to Download Twilio -Java SDK from the Github Repository and add the JAR File to your project classpath.

If you are using any build tools like GRADLE or MAVEN. For Maven Open your 'pom.xml' file and add the dependency below.

<dependency>
   <groupId>com.twilio</groupId>
   <artifactId>twilio</artifactId>
   <version>9.0.0</version>
</dependency>

For Gradle, open your build.gradle file and add this below line.

implementation 'com.twilio:twilio:9.0.0'

Java Code to Send the SMS

Simply Add Java Code Which is given Below ?

import com.twilio.Twilio;
import com.twilio.rest.api.v2010.account.Message;
import com.twilio.type.PhoneNumber;

public class SmsSender {
   // Your Account SID and Auth Token from Twilio
   public static final String ACCOUNT_SID = "your_account_sid";
   public static final String AUTH_TOKEN = "your_auth_token";

   public static void main(String[] args) {
      // Initialize the Twilio client with your Account SID and Auth Token
      Twilio.init(ACCOUNT_SID, AUTH_TOKEN);

      // Create and send the SMS message
      Message message = Message.creator(
         new PhoneNumber("+1234560"), // Recipient's phone number
         new PhoneNumber("+0987651"), // Your Twilio phone number
         "Hello, this is a test message from Tutorialspoint!") // Message body
         .create();

         // Print the unique ID of the message
         System.out.println("Message SID: " + message.getSid()
      );
   }
}

Note: Sending SMS via Twilio or any other platform can incur charges. Take note of local laws regarding sending SMS messages.

Conclusion

By following these steps, you can successfully send an SMS alert to a saved contact using Java.
