If you need to add files from an InputStream (maybe you're on Google App Engine), here is how.
If you need to add files from an InputStream (maybe you're on Google App Engine and have the contents in a byte array), here is how.

```java
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;
import java.io.IOException;
import java.io.ByteArrayInputStream;

SendGrid sendgrid = new SendGrid("sendgrid_username", "sendgrid_password");
sendgrid.addTo("example@example.com");
...
try {
InputStream is = new FileInputStream("c://filename");
is.close();
byte[] contents = somehowGenerateAttachmentContents();

SendGrid.Attachment attachment1 = new SendGrid.Attachment("filename.txt", is);
sendgrid.addFile(attachment1);
SendGrid.Attachment attachment1 = new SendGrid.Attachment("Invoice.pdf", new ByteArrayInputStream(contents));
sendgrid.addAttachment(attachment1);

sendgrid.send();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
