Which statement is correct about the "a" and "b" after running following lines of code? Date a = new Date(12, 31, 1999): Date b = new Date(1, 1, 2011): b = a: Just programmer can free the memory of the second Date object a and b refer to different memory locations but each location contains equal objects the second Date object is orphaned object but it is still accessible Java garbage collection will remove the second Date object
