How to Performing Bitwise Operations on a Bit Vector?

import java.util.BitSet;
public class Main {
public static void main(String[] argv) throws Exception {
// Create the bitset
BitSet bits = new BitSet();

// Set a bit on
bits.set(2);

// Retrieving the value of a bit
boolean b = bits.get(0);
b = bits.get(2);

// Clear a bit
bits.clear(1);

// Setting a range of bits
BitSet bits2 = new BitSet();
bits2.set(1, 4);

// And'ing two bitsets
bits.and(bits2);

// Xor'ing two bitsets
bits.xor(bits2);

// Flip all bits in the bitset
bits.flip(0, bits.length());

// Andnot'ing two bitsets
bits.andNot(bits2);

// Or'ing two bitsets
bits.or(bits2);

}
