Run Sudo Linux Commands From Java Program

I want to find information about running sudo commands from java, but without gksudo/kdesudo.

This is my code. It works, but after removal "sudo" element.

Java Code:

String array[]={"sudo", "dolphin"};
Process proc = null;
try {
proc = Runtime.getRuntime().exec(array);
}
catch (IOException e) {
e.printStackTrace();
} mh_sh_highlight_all('java');

How I can insert password in this terminal? I tried write pass after array with commands and in, and even in outputstream.
