  • The example shows how to monitor and catch an exception.

  • Trying to access an index outside the bounds of an array generates an ArrayIndexOutOfBoundsException.

  • The program intentionally causes this exception and catches it.

Exemplo de exceção simples

  • The code to be monitored for exceptions is placed inside a try block.

  • When an exception occurs, it is thrown and caught by the catch block, ending the try block.

  • Control is not "called" to catch, but is transferred automatically.

  • If no exception occurs, the catch block will be ignored and the program continues normally after the try block.

  • Exceptions raised by methods within the try block can also be caught by catch, if the method does not handle the exception on its own.

Exemplo de exceção simples

  • The exception generated by genException() is caught by the catch block in the main() method, as it was called within a try block.

  • If genException() had caught the exception, it would not have been passed to main().
