Whats wrong with my code

your logic is correct, but you just messed up with the variables and scope things in java.
your class Node() has a constructor … there is a error in first line… it should be
this.data = data;

Now your class merge has a static variable head and static variables are shared among all objects of class, so list1.head and list2.head are same, which is a problem here.

try to fix these things and let me know if you still stuck.
thanks
