Piping commands in Java

I know there are a lot of links on this topic but none of them exactly answered my problem.

From my Java program I need to exec the following command:

sudo nohup hcidump --raw|myProgram arg1 arg2

My approach:

 String[] cmd = {"/bin/sh", "-c", "sudo nohup hcidump --raw | myProgram arg1 arg2"};
Process p = Runtime.getRuntime().exec(cmd);

However, I get a usage error for sudo.

Any suggestions on how I can pipe this?
