jar - how to run java file in window powershell -

i know there similar questions out there none of solutions work case. tried execute java file using windows powershell.

this have java file:

public class demo1 { public static void main (string arg[]){ system.out.println("demo1 start running"); seek { thread.sleep(4000); } grab (interruptedexception e) { // todo auto-generated grab block e.printstacktrace(); system.out.println("unable process"); } system.out.println("demo1 java completed."); } }
