Interview questions , the following code is what is wrong with the

1. if(username.equals("zxx"){}
  	2.	int  x = 1;
  		return x==1?true:false;

------ Solution ------------------------------------- -------
first one username may be null null pointer exceptions should be placed in front of the zxx
second trinocular operation is redundant, direct return x == 1 on the line
------ Solution ---------------- ----------------------------
on the first floor are finished
1 when comparing constants and variables , constants, up front , to avoid variable is empty due to a null pointer
2 return x == 1 is enough, back ? : superfluous , pointless
