Java OCA OCP Practice Question 529

Question

Given the following classes,

what is the maximum number of imports that can be removed and have the code still compile? 

package mypkg; //w  ww  .  j a va 2 s . c o m
public class Water { } 

package mypkg; 
import java.lang.*; 
import java.lang.System; 
import mypkg.Water; 
import mypkg.*; 

public class Tank { 
  public void print(Water water) { 
   System.out.println(water); 
  } 
}
  • A. 0
  • B. 1
  • C. 2
  • D. 3
  • E. 4
  • F. Does not compile. 


E.

Note

The first two imports can be removed because java.lang is automatically imported.

The second two imports can be removed because Tank and Water are in the same package, making the correct answer E.

If Tank and Water were in different packages, one of these two imports could be removed.

In that case, the answer would be option D.
