Why is the double value not exact?

Question

Java

When increasing the value of double, floating point values ​​are not exact, for example:

public class Main{

    static double ii = 0;

    public static void main(String[] args) {
              for (double i = 0; i <= 10; i+=0.000_001) {
            ii+=0.000_001;
        }
        System.out.println(ii);
    }
}

As a result, I get: 10.000000999267517
Why can't I get exactly 10?

Why is this happening?
