How to find out the PID (process ID) of processes in Windows

Problem
If I would like to find out the PID of javaw.java proecess, how do I do?
Windows task manager seems does not have PID information.

Solution 1
View-->Selected Columns-->Checked PID-->OK

Then we can find out the PID information.

Solution 2

Open command prompt, and execute tasklist /fi "Imagename eq JAVAW.exe"

Then we can get the PID information

映像名稱                       PID 工作階段名稱      工作階段 #    RAM使用量

========================= ======== ================ =========== ============

javaw.exe                    10368 Console                    1  1,620,884 K
