title: What is the reverse operation of bitwise AND?
body: <p>How can I get <code>a</code> from <code>b</code> and <code>c</code>? What would be the reverse operation? </p>
  
  <p>Here is the code:</p>
  
  <pre><code>class  s
  {
      public static void main(String ar[])
      {
  
          int a = 20;
  
          int b = 5;
  
          int c = 0;
  
          c = (a &amp; b) ;
  
          System.out.println(c);
  
          int d = (c &amp; b);
  
          System.out.println(d);
      }
  }
  </code></pre>
