Simple onCommend does't work.

Code:java

@Override
public boolean onCommand(CommandSender sender, Command cmd, String label,String[] args){
if(args.length==0){
sender.sendMessage(plugin.getConfig().getString("Broadcast.Prefix"));
return true;
}
if(args[0] == "prefix"){
if(args.length==2){
plugin.getConfig().set("Broadcast.Prefix", args[1]);
sender.sendMessage("You changed prefix to ->" + plugin.getConfig().getString("Broadcast.Prefix"));
return true;
}
else if(args.length==1){
sender.sendMessage(plugin.getConfig().getString("Broadcast.Prefix"));
return true;
}
}
return false;
}

When I type in console "broadcast prefix" it doesn't work.
1. I put command in plugin.yml
2.This onCommand for sure is activated when I type command "broadcast".
3.Eclipse doesn't show anything wrong.
4.When I type "broadcast" command it processes lines from 3-7 correctly. But both "if" statments isn't.
5. I checked if the args are read correctly. They are.

I also noticed that when i change my code to

Code:java

@Override
public boolean onCommand(CommandSender sender, Command cmd, String label,String[] args){
sender.sendMessage(Integer.toString(args.length));
if(args.length==0){
sender.sendMessage(plugin.getConfig().getString("Broadcast.Prefix"));
return true;
}
if(args[0] == "prefix"){
sender.sendMessage(Integer.toString(args.length));
if(args.length==2){
plugin.getConfig().set("Broadcast.Prefix", args[1]);
sender.sendMessage("You changed prefix to ->" + plugin.getConfig().getString("Broadcast.Prefix"));
return true;
}
sender.sendMessage(Integer.toString(args.length));
if(args.length==1){
sender.sendMessage(plugin.getConfig().getString("Broadcast.Prefix"));
return true;
}
}
sender.sendMessage(Integer.toString(args.length));
return false;
}

It is only sending two of four (in lines 3rd and 21th but no in 9th and 15th line) args.lenght value. So if statment (this from 8-20) do something bad (doesnt run)? I don't think that is big problem. I just don't see something.

Or if someone can tell me better way to execute subcommands (like "prefix" here) it would be great.

@AntuaPL You have to use .equals or .equalsIgnoreCase when comparing strings.

Thanks, that worked.
