Java OCA OCP Practice Question 967

Question

Which of the following can replace line 2 to make this code compile?

Choose all that apply 

1: import java.util.*; 
2: // INSERT CODE HERE 
3: public class Imports { 
4:  public void method(ArrayList<String> list) { 
5:    sort(list); 
6:  } 
7: }
  • A. import static java.util.Collections;
  • B. import static java.util.Collections.*;
  • C. import static java.util.Collections.sort(ArrayList<String>);
  • D. static import java.util.Collections;
  • E. static import java.util.Collections.*;
  • F. static import java.util.Collections.sort(ArrayList<String>); 


B.

Note

The two valid ways to do this are import static java.util.Collections.*; and import static java.util.Collections.sort;.

Option A is incorrect because you can only do a static import on static members.

Classes such as Collections require a regular import.

Option C is nonsense as method parameters have no business in an import.

Options D, E, and F try to trick you into reversing the syntax of import static.
