Revisiting Two's complement: A demonstration using Java

public class Main {

    public static void main(String[] args) {

        int number = 10;

        int invertedNumber = ~number;

        int invertedNumberPlusOne = invertedNumber +1;

        System.out.println("Number = " + number);

        System.out.println("Negative number = " + invertedNumberPlusOne);

    }

}

Number = 10

Negative number = -10
