Creating Custom Exceptions

You can create your own exceptions by extending the Exception class.

class MyException extends Exception {
  public MyException(String message) {
    super(message);
  }
}

public class Main {
  public static void main(String[] args) {
    try {
      throw new MyException("Custom error!");
    } catch (MyException e) {
      System.out.println("Caught: " + e.getMessage());
    }
  }
}

This is useful when the standard exceptions don't fit your use case.
