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); 
  }
}
