Private variable problem

ok I have declared a variable as Private Static.

Code:

---

public class tp3

{

private static String allInformation[];
...

---

but in a SUB I do that :

Code:

---

allInformation = new String[10000];
    for (i = 0; i < 10000; ++i)
      allInformation[i] = new String();
  //After that code I start to pu DATA in the ARRAY.
  //All is great since that state.

---

but now I want to use the DATA in the ARRAY in an other sub and I can not find it because it's empty ?

Why?

Usually when I put my declaration Private Static it work everywhere but not now why?

Variable scope problem because your mind has been tainted by VB. Try deallocating it (BTW, do i++, not ++i) or doing this:

Code:

---

String[] toReturn;
// do stuff on toReturn
return toReturn;

what do u mean by " can't find it"?

Anyone know ?

It looks like a scope problem. The String array that you are creating within your method is scoped to that method. Once the method terminates the garbage collector starts to reclaim memory. Try creating a method that takes a String array as an arguement and returns a String array.

OK but how ? It's very important I need to be able to use all data in that array everywhere in the project. Please tell me how to declare it.

Im sure you could use getters and setters and declare your String array which is a member of your class private. This would probably be good if your application has multiple classes.

Ok but how...they didnt learn us to do that and I need to be able to that array in all my class please.

ANy one can give me a piece of code ?

Question is :

Give me the way to declare a simple Array variable who will be able to access the data anywhere in the class.
THANK YOU

It depends on the way the variable is declared and in what context you are trying to access your array. For instance if your array is declared non-static and you are trying to refrence it from a static context then it wont work. The code that you posted.

Code:

---

allInformation = new String[10000];
    for (i = 0; i < 10000; ++i)
      allInformation[i] = new String();
  //After that code I start to pu DATA in the ARRAY.
  //All is great since that state.

you said that in a sub, so i am assuming that you have a method which you are trying too access the String array. You also said that the array is empty or i guess padded with null values, but the block of code you provided only creates (as far as i can see)
empty strings.

Yes that empty then I put data on it but when I am in another sub after have put some data on it I can not access to it why?

Post your code in it's entirety. This was we can get a better picture of whats going on. :p

well thx you but i changed the code and remake one who work now.
