Multidimensional array in java

Question

I have create following string multidimensional array in java. which has top outer array is level(6 levels)and under each level has 4 different sub-level(4 sub levels) and each group has individual 10 set ,that have head and tails.I want to access level1->>sublevel1->set1-->head and tails ...level3->group4->set7->head and tails and so on up to level6->sublevel4->set10->head and tails.

 final String[][][][] myStr = {
                               {
                                 {                                      

                                    {"it", "it was over"},

Java is an OO language. Do yourself a favor and use Collections and Map instead of multi-dimensional arrays — Sean Patrick Floyd

Whatever your problem is, you shouldn't use such a kind of array, because your code will be impossible to understand and unmaintainable.

You should create a Level class, which would give access to a set or list of SubLevel instances, which should give you access to a set or list of Group instances, etc.

This will lead to much more readable code, and allow you to encapsulate behavior in these classes.

Say no to multi-dimensional array, Instead create custom classes if the relation is complex, else use simple Map.

I have no idea what you're actually trying to do, but it looks like you want to do a map from words to the sentence fragment it was found in - try a HashMap<String,String>
