Java Integer.bitCount() is a method in the Java Integer class that counts the number of set bits (1-bits) in the binary representation of an integer. It is often used in bitwise operations, such as in algorithms for calculating checksums, parity, or in cryptography. Introduced in Java 2004 with Java 5, bitCount() is essential for performing efficient bit-level manipulations on integers in Java.
