List if they have perms.

I am making a plugin that lists kits. But I do not know how to make it like a format (like this)

My Kits: kit, kit, kit, kit.

Other Kits: kit, kit, kit, kit.

And lets say they buy a kit it will remove one of the kits from the (other kits) and place it in (my kits) I cant seem to figure this out. I have tried else if statements, if statements. (I want it preferably using perms to list the kits you have)

Does anyone have ideas?

Please I need this quick.

Use StringBuilders.

 

How do I use this.

 

You should learn Java before jumping into plugins. SirLittlemonster7

 

Lazy, go away I don't really care what you think. I am not some kind of 'java god' like you. I am still learning -_- I just started java like a couple months ago.

 

If you've started a couple of months ago then you should understand this.

Assuming you have a List or array... first make sure it has at least one element.
First create a new StringBuilder object and store it, then use append() method with the first element of the list/array as value.
Then start a for() loop with integers starting from 1 to less than list/array's size and on each iteration append ", " and then the list/array's value at that index.

 

Digi that can cause an extra ", " at the end, so it's best to check if the sb.length() > 2 and then sb.setLength(sb.length() - 2) (where your "sb" variable is the StringBuilder) to remove the extra ", " at the end.

EDIT: Never mind, what you have is fine, usually people just loop through and append the art and append a ", ".

 

I dont really get how this works. Could you give me an example.. Also its not a list, or hashmap its a permission that im using.

 

I never actually learned java…I looked at a plugin and just started editing stuff and I learned as I went…Im not the best at java, but Im able to make a TF2 plugin like MCTF2.com for a server that I play on

 

Code:

StringBuilder sb = new StringBuilder();
sb.append(someValue + ",");

You're creating 2 StringBuilder objects there, if you're going to use a StringBuilder don't use concatenation (+), use append().

SirLittlemonster7

Code:

StringBuilder s = new StringBuilder();

for(String name : kitsList) // iterate through all possible kits list
{
    if(player.hasPermissionForThisKit()) // check whatever you want here
    {
        if(s.length() > 0)
        {
            s.append(", ");
        }

        s.append(name);
    }
}

if(s.length() == 0)
{
    s.append("Nothing"); // if player has no kits then do this
}

// Now use s.toString() to print the list.
