Null pointer exception java no suitable driver found code#
Study the following example code to understand the usage of blocks. Your must-always-be-executed code goes between these curly braces, similar to the exception clause
Your exception handling code goes between these Your risky code goes between these curly braces!!! Here is the general form of a try block −
Prints this throwable and it's backtrace to the print writer you specify.īy utilizing the information available from the Exception object, you can catch an exception and continue your program appropriately. Prints this throwable and its backtrace to the print stream you specify. Prints the current exception, or throwable, and it's backtrace to a standard error stream. Gets the next Exception object in the exception chain. For a database error, the five-digit XOPEN SQLstate code is returned. For a JDBC driver error, no useful information is returned from this method. Gets the JDBC driver's error message for an error, handled by the driver or gets the Oracle error number and message for a database error. Gets the error number associated with the exception. The passed SQLException object has the following methods available for retrieving additional information about the exception − Method When such an exception occurs, an object of type SQLException will be passed to the catch clause. SQLException MethodsĪn SQLException can occur both in the driver and the database. JDBC Exception handling is very similar to the Java Exception handling but for JDBC, the most common exception you'll deal with is. If no applicable catch clause exists, then the program's execution ends. The term thrown means that current program execution stops, and the control is redirected to the nearestĪpplicable catch clause. When an exception condition occurs, an exception is thrown. Exception handling allows you to handle exceptional conditions such as program-defined errors in a controlled fashion.
