How to make /accept /decline command?

So i am making a plugin that deals with economy and i dont want to have someone accidently set their balance to $0 or something. So i have 2 questions. how would i make an /accept or /decline command to follow the economy command. Also. If i want to have someone pay back the certain amount that they borrowed within a certain amount of time. how would i make a timer for that? (it would be an extended amount of time (couple of days) Can anyone help?

 

Code:java

if(cmd.equalsIgnoreCase("accept") {
// code here
}

Maybe i wasn't clear. I want the commands to follow after another command confirming what the first command wanted to do.

ie:
Player types /deletebal
Server returns: are you sure? type /accept or /deny

 

I think he means after the player types in a command first, then it allows the player to type in the /accept or /decline command.
EDIT: woops to late

 

Code:java

if(command.getName().equalsIgnoreCase("hi")) {
//code here
    if(command.getName().equalsIgnoreCase("accept")) {
    //code here           
    }
 

 

Take a look at the conversations API for Bukkit it covers exactly this. Heres an example of how to use it https://github.com/rmichela/ConversationsDemo/

 

Code:Java

 
List<String> players = new ArrayList<String>();
Player p = (Player) sender;
if(commandLabel.equalsIgnoreCase("deletebal")){
if(!players.contains(p.getName())){
players.add(p.getName);
//Added player in the list, now we check if he is in it
}
}
if(commandLabel.equalsIgnoreCase("accept")){
if(players.contains(p.getName())){
players.remove(p.getName());
p.sendMessage("You accepted");
return true;
}else{
p.sendMessage("You didnt wrote /deletebal");
return true;
}
}
if(commandLabel.equalsIgnoreCase("deny")){
if(players.contains(p.getName())){
players.remove(p.getName());
p.sendMessage("You denied");
return true;
}else{
p.sendMessage("You didnt wrote /deletebal");
return true;
}
}
}

 

Return the command on deny. This code shoud work ^^
