WHERE AM I WRONG??

Question about the task

Catching custom exceptions

Java Syntax, Level 9, Lesson 8

Under discussion

PLS HELP!!

1. Analyze the exceptions thrown by the BEAN.throwExceptions method.
2. The handleExceptions method must call the BEAN.throwExceptions method and handle exceptions:
2.1. if there is a FileSystemException, then log it (call the BEAN.log method) and rethrow
2.2. if there is a CharConversionException or any other IOException, then just log it (call the BEAN.log method)
3. Add to the handleExceptions method signature the exception class you throw in Item 2.1.
4. In the main method, handle the remaining exception by logging it. Use try-catch

Hint:
If you capture a MyException and you didn't want to catch it, you can rethrow it using code like:
catch (MyException e) { throw e; }

Requirements:

The handleExceptions method must call the BEAN.throwExceptions method.
The handleExceptions method should log the FileSystemException (call the BEAN.log method), and then rethrow it.
The handleExceptions method should only log (call the BEAN.log method) the CharConversionException.
The handleExceptions method should only log any IOException.
Add the FileSystemException class to the signature of the handleExceptions method.
The main method should use try-catch.
The main method should log the exceptions thrown by the handleExceptions method.

package com.codegym.task.task09.task0915; import java.io.CharConversionException; import java.io.IOException; import java.nio.file.FileSystemException; /* Catching custom exceptions */ public class Solution { public static StatelessBean BEAN = new StatelessBean(); public static void main(String[] args) { try{ handleExceptions(); } catch( Exception e){ BEAN.log(e); } } public static void handleExceptions() { try{ BEAN.throwExceptions(); } catch( FileSystemException e){ BEAN.log(e); handleExceptions(); } catch( Exception e){ BEAN.log(e); } } public static class StatelessBean { public void log(Exception exception) { System.out.println(exception.getMessage() + ", " + exception.getClass().getSimpleName()); } public void throwExceptions() throws CharConversionException, FileSystemException, IOException { int i = (int) (Math.random() * 3); if (i == 0) throw new CharConversionException(); if (i == 1) throw new FileSystemException(""); if (i == 2) throw new IOException(); } } }

Line 30: change this: handleExceptions(); to this: throw e; Line 24: add: throws FileSystemException after the objectName i.e.: objectName() throws FileSystemException

public static void handleExceptions() {
// Method is required to have some sort of classification for being able to throw exceptions.
        try{
            BEAN.throwExceptions();
        }
        catch( FileSystemException e){
            BEAN.log(e);
            handleExceptions();
// How should you rethrow an Exception?
        }
        catch( Exception e){
            BEAN.log(e);
        }
    }

Look at this closely. Specifically where I've added comments. I know this is old but hopefully someone can benefit from this if they get stuck.

it says that the handleException method should log and rethrow the FileSystemException, check from the lessons how a method rethrows exceptions
