How-to Replacing strings (case insensitive)?

So I have this code:

Code:java

    @Override
    public void onEnable() {
        saveDefaultConfig();
        final Set<String> messagekeys = this.getConfig().getConfigurationSection("Message").getKeys(false);
        final ArrayList<String> messages = new ArrayList<String>();
        final ArrayList<String> newmessages = new ArrayList<String>();
        for(String messageline : messagekeys) {
            messages.add(this.getConfig().getString("Message."+messageline));
        }
        for(String messages2 : messages) {
            if(messages2.toUpperCase().contains("..PLAYERS..")) {
                System.out.println("Contains ..PLAYERS..");
                Player[] online = getServer().getOnlinePlayers();
                ArrayList<String> names = new ArrayList<String>();
                for(Player player : online) {
                    names.add(player.getDisplayName());
                }
                String players = new String();
                for(String str : names) {
                    if(!(str == names.get(names.size() - 1))) {
                        players = players + str + ", ";
                    }
                    else {
                        players = players + str;
                    }
                }
                if(players == null) players = "None";
                String newmessage = messages2.toLowerCase().replaceAll("..players..", players);
                newmessages.add(newmessage);
            }
            else newmessages.add(messages2);
        }
        Integer interval = this.getConfig().getInt("Interval");
        getServer().getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
 
            @Override
            public void run() {
                for(String line : newmessages) {
                    System.out.println(line);
                }
 
 
            }
 
        }, 0L, interval * 20);
    }

it is supposed to replace a list like:

- Hello
- Players Online - ..players..

to:

- Hello
- Players Online - gomeow

But it does nothing

some other questions:
How do I replace something in a string ignoring case?

Actually, I realize now that first off all, the list check should be players.isEmpty() not == null.
Secondly, I was using ||players|| in my config instead of ..players.. *facepalm*

On another note, I still want to know how to replace something in a string ignoring case

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

string.toLowerCase().replace("derp", "herp");

 

That will make the whole string lowercase. I want it to not care what case it is

 

.equalsIgnoreCase() ?

 

I want to turn something like this
CaSe to hello without testing every possibility of case. Basically I want a method like .replaceALLIgnoreCase(from, to)

 

Wait whut? Then you just need to do what zack6849 said. It will make your variable string lowercase, not your actual message.
You could still do this
string.toLowerCase().replace("derp", "HerP");
This will replace Derp deRp etc. with HerP

Or am I missing something? ;p

 

Here is some code, tell if if this should work:

Code:java

String string = "StRiNg somethingelse";
String newstring = string.toLowerCase().replaceALL("somethingelse", "somethingnew");
//is new string now "StRiNg somethingnew" or "string somethingnew"?

 

Should be "string somethingnew"

 

My point, I want it to be the former.

 

I'd do this:

Code:

String startString = "RaNdOm TeXt REPlAcE Me PleASe!$!";
String finalString = "";
String replaceString = "replace";
int index = startString.toLowerCase().indexOf(replaceString.toLowerCase());
finalString = startString.substring(0, index);
finalString += replaceString;
finalString += startString.substring(index+replaceString.length());

It's EXTREMELY dirty and I'm sure there's a better way, but that's what I thought of off the top of my head...

 

I will go with that if I can't find another method

 

Code:java

String changing = "FirStWOrD GOInGtocHanGe";
String tempwords = "";
for (String words : changing.split(" ")){
String word = "";
if (words.equalsIgnoreCase("goingtochange")){
word = "Changed";
} else {
word = words;
}
if (tempwords.equals("")){
tempwords = word;
} else {
tempwords = tempwords + " " + word;
}
}
changing = tempwords;
//changing will now be "FirStWOrD Changed"

 

I found this somewhere:

Code:

String startString = "RaNdOm TeXt REPlAcE Me PleASe!$!";
String endString = startString.replaceALL("(?i)replace", "this doesn't fit in here");

Haven't tested it yet though

EDIT: Works beautifully!
