Unexpected output found while executing sudo command

When I execute the following command in the terminal, it executes as expected i.e. it displays the current folder contents.

echo <password> | sudo -u root -S ls

But if i execute the same command in my java application, its output is:

<password> | sudo -u root -S ls

How do I overcome this?

When you execute it in the shell, the shell splits the command line according to normal shell rules, i.e. you get "execute echo with parameter <password>, pipe the result to sudo ...".

Java doesn't use the shell, so you're getting "execute echo with parameter <password> | sudo -u root -S ls".
