What’s the Output?

Be very careful. These are diffi cult and a bit tricky.

a. public class Quine   {     public static void main(String[] args)     {       char c = 34;       System.out.print(s + c + s + c + ' ; ' + '} ');     }     static String s1 = "public class Quine{public static void main(String[] args) ";     static String s2 = "{char c = 34;System.out.print(s + c + s + c + '; ' + '} ');} static String s = ";     static String s = s1 + s2;   }

b. public class LinkMeUp   {      private int data;      private LinkMeUp next;      LinkMeUp(int num)      {          data = num * num; next = null;      }

      LinkMeUp()      {          this(0);      }

      LinkMeUp add(int num)      {          LinkMeUp temp = new LinkMeUp(num);          temp.next = this;          return(temp);      }

      void print()      {          LinkMeUp temp = this;          while (temp ! = null)          {              System.out.println(temp.data);              temp = temp.next;          }      }

      public static void main(String[] args)      {          LinkMeUp link = new LinkMeUp();          for (int k = 1; k<10; k++)               link = link.add(k);          link.print();      }   }
