I want to calculate a simple right shift in java, but I don't get correct answer?

Question

I want to get answer 4, but my code prints 2. I don't know why?

public class Test {
    public static void main(String[] args) {
        System.out.println(9 >> 2);
    }
}

Does this answer your question? [What are bitwise shift (bit-shift) operators and how do they work?](https://stackoverflow.com/questions/141525/what-are-bitwise-shift-bit-shift-operators-and-how-do-they-work) — SRJ, Feb 17 '21 at 05:02

Yes it will give you 2

because

9 binary representation is 1001, and when you applied the right shift by 2 it will give you 0010

thats why

9 >> 2 = 2

-2

9=0x1001 does that make the bit shift clear?
