I'm not entirely sure what you're asking, but the code you posted won't compile.
You're using variables named id and token, but you haven't initialized them to anything.
If I were you, I would start smaller: Can you write a program that asks the user for an id and token, saves them to variables, and then simply prints those values back out to the console?
When you have that working, then you can expand it to call the constructor with those variables instead of printing those variables out.
--- Update ---
Nevermind.
