Vault on Command Arguments

Is there a way to use the Vault API on command arguments? Such as withdrawing economy on the command such as /test 1,2,3. I've try'd it but had some errors, fixed the errors and nothing worked. Would love some help!

Code (text):
}else if(args.length == 1) {
if(args[0].equalsIgnoreCase("1")) {
EconomyResponse r = econ.withdrawPlayer(player.getName(), 1.0);
if(r.transactionSuccess()) {
player.sendMessage("1");
Menu.show(player);
Bukkit.broadcastMessage("Test1");
}

else if(args[0].equalsIgnoreCase("2")) {
EconomyResponse r1 = econ.withdrawPlayer(player.getName(), 10.0);
if(r1.transactionSuccess()) {
player.sendMessage("2");
Menu.show(player);
Bukkit.broadcastMessage("Test2");
}

else if(args[0].equalsIgnoreCase("3")) {
EconomyResponse r2 = econ.withdrawPlayer(player.getName(), 10.0);
if(r1.transactionSuccess()) {
player.sendMessage("3");
Menu.show(player);
Bukkit.broadcastMessage("Test3");
}


else if(args[0].equalsIgnoreCase("4")) {
EconomyResponse r3 = econ.withdrawPlayer(player.getName(), 10.0);
if(r3.transactionSuccess()) {
player.sendMessage("4");
Menu.show(player);
Bukkit.broadcastMessage("Test4");
}

EDIT : The first one works but the last 3 don't.

 

Oh my..

Code:java

if (args.length > 0) {
    double amount;
    try {
        amount = Double.parseDouble(args[0]);
    } catch (NumberFormatException ex) {
        sender.sendMessage("Not a number!");
        return true;
    }
 
    //do whatever with 'amount'
    EconomyResponse er = econ.withdrawPlayer(player.getName(), amount);
    //more code
}

 

ErmacOnSteam you miss braces. Basically, you do the following

Code:

if args[0] is "1"
{
    response = econ stuff
    if(response is success)
    {
    }
    else if(args[0] is "2")
    etc...
} 

Which obviously wouldn't work out
