How to create an Array of TreeSet ?

[PierreC]

Hello,

I am writing an application to solve the Sudoku puzzle and I need to create an array that will contain TreeSet objects. The TreeSets will contain String elements.

I have tried the following syntax without result (error messages follows the code):


private final int DIM2=9;

private Set<String>[] ligneGrille = new TreeSet<String>() [9];
private TreeSet<String>[] ligneGrille = new TreeSet<String>() [DIM2];
//array required, but java.util.TreeSet<java.lang.String> found

private Set<String>[] ligneGrille = new TreeSet<String>();
//incompatible tpes :
//found : java.util.TreeSet<java.lang.String>
//required: java.util.Set<java.lang.String>[]


Also, how would I access the TreeSet after it's created?

(Something like :

ligneGrille [0].add("6"); )


I am using NetBeans 4 as IDE.



Thanks for the help,

Pierre C.

Finally, this worked :

private Set[] ligneGrille = new TreeSet [DIM2];

for (int i = 0; i<DIM2; i++) {
ligneGrille[i] = new TreeSet<String> ();
}

Then, I could access it :

ligneGrille[indexX].add(aRemplacer);
