public class BooleanDemo {

   public static void main(String[] args) {

      // create 2 Boolean objects b1, b2
      Boolean b1, b2;

      // create a boolean primitive res
      boolean res;

      // assign values to b1, b2
      b1 = new Boolean(true);
      b2 = new Boolean(false);

      // assign the result of equals method on b1, b2 to res
      res = b1.equals(b2);

      String str = "b1:" +b1+ " and b2:" +b2+ " are equal is " + res;

      // print res value
