i unzipped and went to observer pattern directory...and then compiled the sources.... but iam struck in calling the test code to run the main method..

jithendar,

You need to go up your directory to C:\Users\jithendar\Desktop\headfirst\HF_DP\src and run "java headfirst.observer.weather.WeatherStation" from there
