other computer???

well when i send a packet with let's say 10.0.0.32/24 it well go to the second line in the table
so it sould be sent to the gateway 10.0.0.201 is't that my computer? what does it mean?
maybe it means th connection my router has with my computer then way would the defalt be to 10.0.0.221??
please help me .........................
maybe i don't understand what exactly gateway is (the ip number of the router that connects me to a other network)

yeah thanks i did not notice ...

i do have some experience in wed development but not very much only basic stuf
the question is if i should keep learning java web developing and maybe other things too before i get in too grails or i sould start grails and i'll get the experience on the way?

does learning you'r book require more than basic web development concept?

thanks

Welcome Dave Klein
i am not an expert in web development i am a beginner really ,do you think learning grails
would be good /bad for me and is the book suitable for someone like me?
thanks...

thanks .....

sorry i am new i don't realy understand what is debuging is (i think it is a breakpoint so you can see part of the code)
the Thread.sleep sould stop the first (4-point) polygon from changing for some time then when the move()
is called the JPanel sould clear and the second (4-point) polygon sould apeer with out there remains of the first one
sould not lokk like an airplane tail-(5-point polygon)
i did not understand way it is a progam that has to be run from debuging...

this is my code i do not understand why the jpanel dose not clear when the repaint in move()
act's on the paintComponent()- super.paintComponent;
