I cant understand, why bool b = null; is not valid?

Code: Select all

class bool {}

...
bool b = null;

Did you try compiling it? What error message did you see?

BTW, the explanation explains why it is not a correct option:

bool is an invalid keyword. Therefore, 1 and 4 can't be right. (Although 1 could be right if bool were a user defined class but as per Java coding conventions, a class name should start with a capital letter.)
