Java OCA OCP Practice Question 2914

Question

Suppose that the table food has five rows and this SQL statement updates all of them.

What is the result of this code? 

public static void main(String[] args) { 
   Connection conn = DriverManager.getConnection("jdbc:derby:zoo"); 
   Statement stmt = conn.createStatement(); 
   int result = stmt.executeUpdate("update food set amount = amount + 1"); 
   System.out.println(result); 
}
  • A. 0
  • B. 1
  • C. 5
  • D. The code does not compile.
  • E. A SQLException is thrown.
  • F. A different exception is thrown.


D.

Note

JDBC code throws a SQLException, which is a checked exception.

The code does not handle or declare this exception, and therefore it doesn't compile.

If the exception were handled or declared, the answer would be choice C.
