/*This Java program is to Implement Bit Array. A bit array (also known as bitmap, bitset, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly.*/
