Need help, onCommand input string as value? (if else)

I know java on a beginner level, and can work our most uses for websites etc.

But im am new at using the bukkit api.
i got a few plugins working and running just fine on my "test enviroment" and tested
on my live server worked fine aswell so i got the very basics down..

Now i am trying to use player commands with arguments.
and for this i am trying to make it list <x> items i got.

Here are a few code snippets of my problem..

First of i am using onCommand to get playerchat, after watching dinnerbones tut.

Code:

         public boolean onCommand(CommandSender cs, Command cmnd, String string, String[] args) {

and i get it to respond and work fine, with a command like /elist
but then i want to add the argument of a number int. like this /elist 5
and if the user dosent enter a number just /elist it will automatic select 6 for him.

But i am having problems using the number value,, i have tryid using args[1] but java
says it is a string.

Code:

                    int tempval;
                    if (args[1] > 0) {
                        tempval = args[1];
                    } else {
                        tempval = 6;
                    }

I hope you can understand my logic here.
Check if there is a value above 0 and then assign that value to tempval
if the value is 0 or less then use 6 as tempval..

The error i get is "Bad operand type for binary operator" on the line with the if(args[1] > 0){

any suggestions ?

 

Arguments are passed as strings and not as integers, floats or doubles.
Arrays start counting at 0, so the first argument is args[0] and not args[1].
Check if the player typed an argument or not first via args.length > 0

To get a number out of the argument, use Integer.parseInt(String). It will throw a NumberFormatException if the given String could not be parsed to a number (use try/catch)

This should be enough information for you to figure out your problem.

 

Example of what @Bone008 said with the features you need:

Code:

int tempval = 6;
try {
    if (args.length > 0) {
        tempval = Integer.parseInt(args[0]);
    }
} catch (NumberFormatException e) { /* Continue, You want an default of 6. */  }

It will make an default value for 6, TRIES to replace it with args[0] as integer, but if it couldn't parse it, it will keep it 6 and continue

 

<3 <3 works, thank you!!
