Q91. Which of the following will print current time? 

A. System.out.print(new LocalTime()-now0); 

B. System.out.print(new LocalTime()); 

C. System.ouLprint(LocalTime.now()); 

D. System.ouLprint(LocalTime.today()); 

E. None of the above. 

Answer:

Explanation: 

The LocalTime is an interface, so we can't use new keyword with them. So options A and C are incorrect. To get current time we can call now method on LocalTime interface. So option C is correct. Option D is incorrect as there is no method called today as in LocalTime interface
