There is *something* illegal or wrong about initializing (HuffmanCharFreq)left=null,(HuffCharFreq)right=null as mentioned in Lecture 2.
I refer to 8/30's lecture, pg11, slide #4 which says "null [but where is null, specifically, per this example?] will not respond to any method calls."
If there something wrong about the above, please advise. Otherwise, clarify the lecture notes. |
