Something like this should work:

final SimpleDateFormat parsedDate = new SimpleDateFormat("yyyy-MM-dd");

final Date date;
try{ 
    date = parsedDate.parse(stringValue); 
} catch(Exception e) {
    // handle the exception.
}

You cannot simply cast a String to a Date. To get a Date from a String object which has the String representation of Date, use SimpleDateFormat.

E.g:

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); //Change format according to your needs.
Date date = new Date();
try{
    date = sdf.parse((String)memberValue); //Update:- memberValue.toString() will also work.
}catch(ParseException pe){
    //Do something on Exception.
}
return new SwitchInputType<Date>(date);

You can use:

return new SwitchInputType<Date>(new SimpleDateFormat("MMMM d, yyyy", Locale.ENGLISH).parse(memberValue));

You should first convert the string to date object before assigning to a Date. Use SimpleDateFormat.parse() method to parse the string to a Date object.

Try to create new date object like this Date date = new Date(long) or if you created this string using Date class use its static method Date.valueOf(String s).

If its a string, you need to parse it. Try using SimpleDateFormat with appropriate format.
