How to auto-number a list

What I am doing is there is a help command for how to use the plugin, what I am working on is the sender will only be given information that is currently enabled. I want to know if somehow I can number each one that is enabled so numbers don't skip between enabled features like

1.) blah blah blah
2.) NOT ENABLED
3.) more blahs

but while 2 is not enabled, the number 3 will become 2 and so forth.

Pseudocode:
int index = 0;
for (String information : informations) {
if (information is enabled) {
index++;
print information
}
}

 

I'm not exactly sure I am doing this correctly, this is what I am doing with the code, because I don't know what to put for informations:

Code:

if (args[1].equalsIgnoreCase("sulphur") { // command: /mm help sulphur
  Sulphur.getInfo(sender);
  return true;
}

Here is what I put in the Sulphur getInfo(CommandSender) method:

Code:

public void getInfo(CommandSender s) {
    if (enabled) {
        s.sendMessage("");
        s.sendMessage(ChatColor.AQUA + "" + ChatColor.BOLD + "SULPHUR");
        s.sendMessage("1. " + ChatColor.RED + "Right-click a block to create a mini explosion.");
        s.sendMessage("");
    } else
        s.sendMessage(ChatColor.GREEN + "" + ChatColor.ITALIC + "This Feature is currently off");
}

In your code, I dont see what you have described. Where is the part that would need an auto-number?

 

The information in the p.sendMessage, I would have to link it from a separate String, but I don't really know how :/

In your example, you mentioned the command /mm help sulphur
The output when enabled is:
-
-SULPHUR
-1. Right-click a block to create a mini explosion.
-

If not enabled:
-This Feature is currently off

Now tell me, where should be the auto-number in this example? Or provide a better example what you want to achieve

 

Well in the first example:

SULPHUR
1. Right-click a block to create a mini explosion.
2. Blah blah blah
3. blah blah blah

if say 2 is not enabled, it will not display, and 3 will become 2.
