How to implement addition of two binary numbers in Java?
For example, there is a number int - 11111010 and you need to add the number to it according to the rules of addition of binary numbers:
00000001. How to do it ?

Answer 1

Integer.toBinaryString(Integer.parseInt("11111010", 2) + Integer.parseInt("00000001", 2))

Answer 2

If your number is already int, then take it and add it with the addition operator ("+" for those who skipped math).
Otherwise, translate your (most likely) string representation into int, long or BigInteger, and work with it already.
