Hi @Sandesh Santram Giram

Make sure the user has an O365 license.
Make sure you are using the application context to send mail on behalf of the user, not the delegated context.

Refer to the complete sample code:

final ClientSecretCredential clientSecretCredential = new ClientSecretCredentialBuilder()
                .clientId("xxxxxxxxxxxxxx")
                .clientSecret("xxxxxxxxxxxxx")
                .tenantId("xxxxxxxxxxxxxxxxxxxx")
                .build();

        List<String> scopes = new ArrayList<>();
        scopes.add("https://graph.microsoft.com/.default");

        final TokenCredentialAuthProvider tokenCredentialAuthProvider = new TokenCredentialAuthProvider(scopes, clientSecretCredential);

        final GraphServiceClient graphClient =
                GraphServiceClient
                        .builder()
                        .authenticationProvider(tokenCredentialAuthProvider)
                        .buildClient();

        Message message = new Message();
        message.subject = "xxxxxxxxxxxxxx";
        ItemBody body = new ItemBody();
        body.contentType = BodyType.TEXT;
        body.content = "xxxxxxxxxxxx";
        message.body = body;
        LinkedList<Recipient> toRecipientsList = new LinkedList<Recipient>();
        Recipient toRecipients = new Recipient();
        EmailAddress emailAddress = new EmailAddress();
        emailAddress.address = "xxxxxxxxxxxxx";
        toRecipients.emailAddress = emailAddress;
        toRecipientsList.add(toRecipients);
        message.toRecipients = toRecipientsList;
        LinkedList<Recipient> ccRecipientsList = new LinkedList<Recipient>();
        Recipient ccRecipients = new Recipient();
        EmailAddress emailAddress1 = new EmailAddress();
        emailAddress1.address = "xxxxxxxxxxxxxxxxx";
        ccRecipients.emailAddress = emailAddress1;
        ccRecipientsList.add(ccRecipients);
        message.ccRecipients = ccRecipientsList;

        boolean saveToSentItems = false;

        graphClient.users("xxxxxxxxxxxxxxxxx")
                .sendMail(UserSendMailParameterSet
                        .newBuilder()
                        .withMessage(message)
                        .withSaveToSentItems(saveToSentItems)
                        .build())
                .buildRequest()
                .post();

Hope this helps.
