Answer #1
d) “SQLException” and “Continue” Explanation: ------------- DBClass.batchUpdate(); //throws BatchUpdateException BatchUpdateException is a subclass of SQLException so, catch(SQLException) block will catch this exception and it's body is executed, which prints SQLException and the code after this try-catch block will continue executing as normal, which prints Continue hence the output to this code is SQLException Continue
