How can I add this exact layout to the config?

I need to add the exact layout to the config on the command /helpmenu add <name>. They will then edit the menu in the config.

example:
1: "&8&m====================================================="
2: "&a&l Help > Example"
3: "&3/spawn &7- Go to the server spawn."
4: "&3/spawn &7- Go to the server spawn."
5: "&3/spawn &7- Go to the server spawn."
6: "&3/spawn &7- Go to the server spawn."
7: "&3/spawn &7- Go to the server spawn."
8: "&3/spawn &7- Go to the server spawn."
9: "&3/spawn &7- Go to the server spawn."
10: "&3/spawn &7- Go to the server spawn."
11: "&8&m====================================================="

I also need to check if the page already exists before I add it.

How could I go about this?

 

Something like this:

Code:java

for (int i = 1; i < 1000; i++) {
if (!getConfig().contains(i + "") {
getConfig().set(i + "", "text");
saveConfig();
break;
}
}
