How to pass any type of data to HashMap?

Question

Java

Hello, I'm interested in how you can transfer any type of data to HashMap, for example

HashMap m = new HashMap<Sring, ?>();
m.put("one", 1);
m.put("two", "2");
m.put("new", 2.3);

I will be very grateful

Answer 1

HashMap<String, Object>
But usually this is a bad idea.
PS And String, not Sring, I guess.
