selenium webdriver - Error in java package -

@test  private void autoittest() throws ioexception {    java.lang.runtime().getruntime().exec("c:\\selenium\\framework\\autoitpopuphandler.exe"); }      

error prompted @ java.lang please provide appropriate solution.

runtime class, don't "call" it. should like:

runtime.getruntime().exec("c:\\selenium\\framework\\autoitpopuphandler.exe"); 

qualifying java.lang not needed, won't hurt anything.
