Arithmetic Operations on Arbitrary-Length Binary Integers in Java

Date: 2024-08-23

Java supports binary integer arithmetic, handling both fixed-length (int, long) and arbitrary-length integers using the BigInteger class. Binary literals are declared with the 0b prefix. Integer.bitCount() and Long.bitCount() determine the number of set bits. BigInteger performs arithmetic operations (add, subtract, multiply, divide) on arbitrarily large numbers, effectively using two's complement representation. While primitive types require unsigned arithmetic methods, BigInteger handles this implicitly. This allows for calculations without overflow issues.
