public class ExceptionTest {

    public static void main(String[] args) {
        throw new ExceptionIsNotTheLastWord();
    }
}

class ExceptionIsNotTheLastWord extends Exception {

}

...the resulting code will be like this:

public class ExceptionTest {

    public static void main(String[] args) {
        try {
            throw new ExceptionIsNotTheLastWord();
        } catch (ExceptionIsNotTheLastWord exceptionIsNotTheLastWord) {
            exceptionIsNotTheLastWord.printStackTrace();
        }
    }
}

class ExceptionIsNotTheLastWord extends Exception {

}

IDEA generates a short name for the exception only, when the exception's class name ends with "Exception". This also affects catching the Throwable class - IDEA will generate "catch (Throwable throwable)" even though it would look better as "catch (Throwable t)".

EXPECTED

• For Throwable, use "t" as the variable name. For all other exceptions, use "e" as the variable name. (I think this would be the best method, what the programmer would except.)
  OR
• When creating a catch statement, use the first letter of the last word in the exception's class name as the variable name for the exception.
