How to read from the remote file into a Stream ?

Can anyone please help in reading a remote file into a Stream? I understand that I need to use something similar to this
```
sftpClient.get("/home/sftp/file1", new InMemoryDestFile() {
@Override
public OutputStream getOutputStream() throws IOException {
return null;
});
```
but any process on how exactly to do this would be helpful. Thanks in advance
