I'm so lost. How do I throw and exception that's in an extends class

Question about the task

We're all friends here, even the exceptions

Under discussion

I have no clue what to do now. I tried throwing an exception right after the extends code and that ended in an error. I also tried to throw the error in the body of the method and had errors. Please help. Thank you for your assistance.

There are four classes: MyException, MyException2, MyException3, and MyException4.
Inherit the classes so that you get any two checked exceptions and any two unchecked exceptions.

Hint:
Carefully study the Exception1, Exception2, and Exception3 classes from the second task in this lesson.

Requirements:

The Solution class must have 4 nested classes: MyException, MyException2, MyException3, and MyException4.
All the nested classes must inherit exception classes.
Two of the four classes must be checked exceptions.
Two of the four classes must be unchecked exceptions.

package com.codegym.task.task09.task0918; /* We're all friends here, even the exceptions */ public class Solution { public static void main(String[] args) { } class MyException extends Exception() throws IOException { } class MyException2 extends MyException{ throws new IndexOutOfBoundsException(); } class MyException3 extends MyException2 { } class MyException4 extends MyException3 { } }

The code body for classes can only contain fields, methods, constructors, and internal classes (and comments). Line 16 is an expression and is not included in what can be contained in the class body. This is where you are getting an error. This task is not asking you to throw an exception, or write any expressions, either. It just wants you to inherit exception classes on the classes provided. I recommend resetting the task then extending what was done here correctly on the other 3 classes. You should look up which exception classes are checked and which are unchecked.

I brought my code back to extend each class, but how to I do the checked and unchecked tasks?

public class Solution {
    public static void main(String[] args) {
    }

    class MyException extends Exception
    {
    }
    class MyException2 extends MyException {
    }

    class MyException3 extends MyException2 {
    }

    class MyException4 extends MyException3 {
    }
}

you have to extend 2 checked exception classes and 2 unchecked exception classes. In your original code line 12 was almost correct. The IOException class is a checked type exception. You should extend that instead of "throw".
