Java OCA OCP Practice Question 2064

Question

Given the following code snippet and the table, what is the output of the following when using a driver that supports a scroll sensitive ResultSet?. 

rst_name                 last_name //from   w  ww  .j a  v a2  s.com
character varying(255)   character varying(255) 
Java                     Server 
Javascript               Client 
HTML                     Makup 
SQL                      Database 


try (Connection conn = DriverManager.getConnection(url); 
   Statement stmt = conn.createStatement( 
      ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY); 
   ResultSet rs = stmt.executeQuery( 
     "select * from people order by last_name asc")) { 


   rs.absolute(-1); 
   System.out.print(rs.getString(1)); 
   System.out.print(" "); 
   rs.absolute(1); 
   System.out.print(rs.getString(1)); 
}
  • A. Java SQL
  • B. SQL Java
  • C. The code compiles, but the output is neither of these.
  • D. The code throws a SQLException at runtime.


B.

Note

When passing a negative number to absolute(), Java counts from the end instead of the beginning.

The last row is SQL's row, so the first print statement outputs SQL.

When passing a positive number to absolute(), Java counts from the beginning, so Java is output.

Option B is correct.
