Do not expect command on Java DS overnight. It is ocean, until and unless not properly approached, it leaves in a very great confusion, of course without pointers (feeling of when you lost alone in an unknown forest). It is a ocean due number of classes, and these classes are given to make your programming easy (not to confuse you). I feel the following is a better way to penetrate into DS; follow the following order of reading.

A) General Programs
1. Collections Framework
2. Collections Interfaces Hierarchy
3. Interface Collection
   

4. Stack
5. Generics Stack
   

6. Vector Methods
7. Vector Generics
8. Vector Retrieval
9. Vector Play With
   

10. Hashtable About
11. Hashtable General
12. Hashtable Generics
13. Hashtable Special
    

14. Properties
    

15. List Fundamentals
16. List Methods
17. List Iteration
18. List Reversing Sorting
19. List Unique Elements
    

20. Queue Fundamentals
21. Queue Programming
    

22. ArrayList Introduction
23. ArrayList Methods
24. ArrayList Iterators
25. ArrayList Operations
26. ArrayList Special
27. ArrayList of arrays
28. Array of Array Lists
    

29. LinkedList Tutorial
30. LinkedList General
31. LinkedList Special
32. LinkedList Iterators
    

33. interface Set Tutorial
    

34. HashSet Tutorial
35. HashSet General
36. HashSet Operations
    

37. interface SortedSet
    

38. TreeSet Tutorial
39. TreeSet General
40. TreeSet Special
    

41. interface Map Tutorial
42. interface Map Methods
    

43. HashMap Tutorial
44. HashMap Genreral
45. HashMap Iteration
46. HashMap Sort
    

47. interface SortedMap Tutorial
    

48. TreeMap Tutorial
49. TreeMap General
50. TreeMap Special

B) Elements Iteration (retrieving and printing the elements)

C) Elements sorting Customization
1. interface Comparable
2. Comparable Example
3. interface Comparator
4. Comparator Example
5. Comparable vs Comparator

D) Elements Manipulation made easy. Boon to Programmer
1. Reversing elements with reverse()
2. Count of same element existance with frequency()
3. Replacing elements with replaceAll()
4. Finding Min and Max values with min() and max()
5. Sorting ArrayList with sort()
6. Sorting ArrayList with Comparator
7. Searching an element with binarySearch()
8. Copying one list to another with copy()
9. Swapping two elements with swap()
10. Shuffling the elements randomly with shuffle()
11. Rotating elements with rotate()
12. Filling List elements with fill()
13. Existence of Common Elements with disjoint()
14. Adding Array to Collections classes with addAll()
15. Finding Sublist Index with indexOfSubList()
16. Immutable Collection with unmodifiableCollection()
17. Thread-safe Collection with synchronizedCollection()
18. Type-safe Collection with checkedCollection()
19. Enumerated Collection with enumeration()
20. Enumeration to ArrayList with list(Enumeration)
21. Immutable List with nCopies()
22. Singleton List with singletonList()
    
    Would you like to know similar operations on array elements? Array elements manipulation made easy.

E) Miscellaneous. Makes you away from confusions. Important for interviews.
1. DS features added in JDK 1.5
   

2. Vector vs ArrayList
3. ArrayList vs LinkedList
4. Array and ArrayList
   

5. Set vs HashSet
6. HashSet vs TreeSet
   

7. Map vs HashMap
8. Hashtable vs HashMap
9. HashSet and HashMap
10. HashMap vs TreeMap
    

11. Comparable vs Comparator
    

12. Enumeration vs Iterator
13. Iterator vs ListIterator
