How to know datatype of a variable in Java ?

Question

In python we have type() function but how can i know the datatype of variable in Java?

Answer 1

Depends what you exactly mean by a variable. But for an object it should be getName and getClass.
Also there is something called instanceOf which I think for the array list

Answer 2

You can find the type only for reference type variables.

String str = "hello";
System.out.println(str instanceof String);
OR
System.out.println(
str.getClass().getName());
