Question

I created my own exception class:

public class ApplicationException extends Exception 
{
    public ApplicationException()
    {
        super();
    }

    public ApplicationException(String message)
    {
        super(message);
    }
}

This warning is shown: “The serializable class ApplicationException does not declare a static final serialVersionUID field of type long”. How can I fix this?

Answer 1

Simply define a variable named serialVersionUID with a type long

private static final long serialVersionUID = 1L;
