Global array not accessible

[slugger_2003]

Hi all,

basic question...I'm a bit rusty with Java so bare with me.
As far as I could remember, putting the keywork "public" before the variable should do this but in my application it isn't.

See the code snippet here:

public class controller extends MIDlet implements TargetListener, CommandListener
//public class controller extends MIDlet
{
        public page navigatePages [] = new page [3];    //Holds the previous page, current page and next page, much like a web browsers history.

Thanks in advance for any relevant views or opinions.

If the variable is marked Public it can accesses everywhere within the class and also outside the class with the Object of the class in which it is defined.

If it's public static then in that case, it can directly used as className.variable from outside the class in the same package or imported/linked packages.

thanks,

Please post your thread in more descriptive form,..

public class controller extends MIDlet implements TargetListener, CommandListener
//public class controller extends MIDlet
{
        public page navigatePages [] = new page [3];    //Holds the previous page, current page and next page, much like a web browsers history.

Here is few basic and quick questions for you to answer, and to guess the reason for the issue,

1. Have you created and defined the class page in you project?
2. Was you project compile successfully?
3. Or are you getting the error at the time of writing the code and IDE displays the RED lines at this point where you are trying to access this targeted array?

I was trying to utilise the variable navigatePages without creating an instance of it's container class, I thought this only needed to be done for private variables but was confusing it with public static. Consider this to be some rust removed from my Java hat...still in need of some oil though...

Please explain, what do you mean to say

[slugger_2003]

I presume you had difficulty understanding my statement "Consider this to be some rust removed from my Java hat...still in need of some oil though". I basically meant that I had forgotten the rules of variable scope but now I remember.
Problem is solved now though, thanks.
