Answer 1.

The statement “If the driver for MySQL is not in the class path, the program will have a syntax error” is false.

In this case if the driver for MySQL is not in the class path, it will give ClassNotFoundException.

The option 3 is false.

Answer 5.

The statement “The finally block and try block can appear in any order” is false because there is a specific order of execution of the try-catch and finally blocks. The body of try is executed first. If an exception is thrown, the appropriate catch clause is executed. The finally block is executed at the end.

The option 3 is false.
