If the BadDateException class is a programmer-defined exception class, which of the following constructors should be coded in that class?

public BadDateException(String s){...}

public BadDateException(Exception e){...}

public BadDateException(Throwable t){...}

public BadDateException(String s, Exception e){...}

Both checked and unchecked exceptions

can be caught in a try/catch statement

are derived from the Error class

are found during compile time

require an exception handler
