Simple 5 Steps to Send Email using Java and Gmail | With out Less Secure App | Hindi

In this video, we will be learning how to send an email with an attachment using Java and Gmail in Hindi. We will be using the JavaMail API library to accomplish this task.
First, we will start by adding the JavaMail API dependency to our project. This can be done by adding the following code to our build file.
Next, we will go over the code for sending an email with an attachment. We will be using the Properties class to set up our email server properties, and the Session class to create a session for sending the email.
We will then use the MimeMessage class to create the email message, and the MimeBodyPart and Multipart classes to attach the file to the email.
We will also show how to handle any errors that may occur during the sending process and how to authenticate the Gmail account that is being used to send the email.
This video will be a step-by-step guide for sending an email with an attachment using Java and Gmail in Hindi, and will be useful for beginners and experienced programmers alike.
