Get the own process pid from the command prompt in windows

Question

I'm trying to get the PID from command prompt of its own. But when using the below command i'm not getting the desired output always. Can you please point out what was the error in the below statement?

cmd.exe /c title="mycmd" & tasklist /v /fo csv | findstr /i "mycmd" & dir & help

Edit:

The below command working correctly. But when combine it with two more commands. It's not working.

cmd.exe /c title="mycmd" & tasklist /v /fo csv | findstr /i "mycmd"

Additional Info:

I'm using Java

final List<String> commands = new ArrayList<String>();                

commands.add("cmd.exe");
commands.add("/C");

//.. Add more commands

ProcessBuilder pb = new ProcessBuilder(commands);
