Unchecked exception

Question

I try to Create a custom unchecked exception class called InvalidDateException. This exception class must include a constructor that takes a String as an argument. But I wonder is my code is custom unchecked exception or not.

class InvalidDateException extends RuntimeException
{
      //Parameterless Constructor
      public WordContainsException() {}  

      //Constructor that accepts a message
      public InvalidDateException(String message)
      {
         super(message);
      }
 }

In order to create a unchecked exception, you must extend RuntimeException. — cassiomolin, Sep 18 '14 at 18:50
When you have an unchecked exception, you are not required to use try-catch. — cassiomolin, Sep 18 '14 at 18:52

Since your class extends Exception, it's a checked exception. If you want to create an unchecked exception, you should extend RuntimeException.
