c++ - Accessing inactive union member and undefined behavior? -

JAVA - what is the difference between void and boolean methods? -

i new java. writing wrapper-library in java make functions available in basic-like language. i got stock @ point when noted code not executed in java-library although compiler did not complain (using eclipse). resolved replacing code follows: public void videoquality(int vquality) //did not work into public boolean videoquality(int vquality) //works here complete code-snippets: public void videoquality(int vquality) //did not work {if (vquality==16) { vidquality=16; } else if (vquality==-16) { vidquality=-16; } else if (vquality==0) { vidquality=0; } else vidquality=-16; vitamioext.setvideoquality(vidquality); } public boolean videoquality(int vquality) //works {if (vquality==16) { vidquality=16; } else if (vquality==-16) { vidquality=-16; } else if (vquality==0) { vidquality=0; } else vidquality=-16; vitamioext.setvideoquality(vidquality); return true; } i think void corresponds sub in visual basic while boolean corresponds function. i found odd following code worked using...
