未经检查的异常

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);
      }
 }

Answer 1

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

Answer 2

是的，您的Exception类是未经检查的异常类，因为您已经使用RuntimeException进行了扩展。
