How to create a properties file

That's basically it. I want to know how to create a properties files, and have one property I can access from it.

 

Watch samkio's intermediate tutorial

 

Load the file

Code:

FileInputStream r = new FileInputStream(fileName);
Properties file = new Properties();
file.load(r);

get something from the file

Code:

file.getProperty(key,defaultResult)

 

Loading it creates it?

 

That is how to load it and use it... If you do getConfiguration it holds an instance of a file object even if it doesn't exist on the file system. So what you do is build a quick sample configuration in code and the save the configuration and taht will create it for you. So this is the one I have from DropBonus (ignore all my constants...)

Code:

    protected void buildConfiguration()
    {
        Configuration c = getConfiguration();
        if (c != null)
        {
            c.setProperty(DropBonusConstants.BONUS_PREFIX +
                Material.STONE.toString().toLowerCase() +
                DropBonusConstants.BONUS_PROBABILITY_SUFFIX, 20);

            List<Double> vals = new ArrayList<Double>();
            vals.add(new Double(100));
            vals.add(new Double(100));
            c.setProperty(DropBonusConstants.BONUS_PREFIX +
                Material.STONE.toString().toLowerCase() +
                DropBonusConstants.BONUS_CHANCES_BRIDGE +
                Material.COBBLESTONE.toString().toLowerCase(), vals);

            String valarr = ".1 0 1";

            c.setProperty(DropBonusConstants.BONUS_PREFIX +
                Material.STONE.toString().toLowerCase() +
                DropBonusConstants.BONUS_CHANCES_BRIDGE +
                Material.OBSIDIAN.toString().toLowerCase(), valarr);
            c.setProperty(DropBonusConstants.BONUS_PREFIX +
                Material.STONE.toString().toLowerCase() +
                DropBonusConstants.BONUS_OVERRIDE_SUFFIX, false);

            c.setProperty(DropBonusConstants.BONUS_PREFIX +
                Material.STONE.toString().toLowerCase() +
                DropBonusConstants.BONUS_TOOL_BRIDGE +
                Material.DIAMOND_PICKAXE.toString().toLowerCase() +
                DropBonusConstants.BONUS_CHANCES_BRIDGE +
                Material.STONE.toString().toLowerCase()
                , 100);

            c.setProperty(DropBonusConstants.BONUS_PREFIX +
                Material.STONE.toString().toLowerCase() +
                DropBonusConstants.BONUS_MAXNUMBER_SUFFIX
                , -1);

            c.setProperty(DropBonusConstants.BONUS_PREFIX +
                DropBonusConstants.CRAFTCHICKEN +
                DropBonusConstants.BONUS_PROBABILITY_SUFFIX, 99.9);
            c.setProperty(DropBonusConstants.BONUS_PREFIX +
                DropBonusConstants.CRAFTCHICKEN +
                DropBonusConstants.BONUS_CHANCES_BRIDGE +
                Material.EGG.toString().toLowerCase(), 99.9);

            if (!c.save())
            {
                getServer().getLogger().warning("Unable to persist configuration files, changes will not be saved.");
            }
        }
    }

Since I have this in a method call I just call it from onEnable.
