throws --> throws declare that it throws the exception to
the calling method.

throw --> it is surrounded by the try catch block actually
it does the work, of throwing the exception.

For Example:

public void testMethod() throws BusinessException
{
try
{
}
catch(Exception exe)
{
// catch all the exceptions and provide some meaningful
message
throw BusinessException("An error occured while
trying to connect to DB");
}

}
