Java OCA OCP Practice Question 19

Question

Given that a Date class exists in both the java.util and java.sql packages, what is the result of compiling the following class? 

1: import java.util.*; 
2: import java.sql.*; 
3: public class BirthdayManager { 
4:    private Date d = new Date(); 
5:    private java.util.Date my = new java.util.Date(); 
6: }
  • A. The code does not compile because of lines 1 and 2.
  • B. The code does not compile because of line 4.
  • C. The code does not compile because of line 5.
  • D. The code compiles without issue. 


B.

Note

The fact that the Date class exists in both packages does not impact the ability to import both packages, so lines 1 and 2 compile without issue, and Option A is incorrect.

Line 4 will not compile because the Date class used is ambiguous, making Option B correct and Option D incorrect.

Option C is incorrect because line 5 does compile, as the fully qualified name of the class is used.
