While programming in Java in my latest version of netbeans, whenever I try to execute my program it shows null pointer exception though I have declared and initialized the variables.

I have JDK 6 installed in my computer. Applications in command prompt or Swing based applications work completely fine. Problem is with applets. When I tried to run my applet in Google Chrome, it shows a blank area and the error shown is,"Java(TM) is required to display some elements on this page". In front of that, a "Install plug in" option is there. I clicked it and it shows download java. It is not the plug in, it's again the whole JDK. I have JDK already installed, why should I again download it? Please tell some alternatives.
