Java OCA OCP Practice Question 2723

Question

Given the proper imports and given: 

81.    String in = "1234,77777,689";  
82.    Scanner sc = new Scanner(in);  
83.    sc.useDelimiter(",");  
84.    while(sc.hasNext())  
85.      System.out.print(sc.nextInt() + " ");  
86.    while(sc.hasNext())  
87.      System.out.print(sc.nextShort() + " ");

What is the result?

  • A. 1234 77777 689
  • B. Compilation fails.
  • C. 1234 77777 689 1234 77777 689
  • D. 1234 followed by an exception.
  • E. 1234 77777 689 followed by an exception.
  • F. 1234 77777 689 1234 followed by an exception.


A is correct.

Note

The first while loop "consumes" the Scanner object, so the second while loop has nothing to process.

If the first while loop didn't exist, the second while loop would throw an out of range exception because shorts cannot be larger than 32767.
