Thread: Problem With Properties (+SSCEE)

It won't load the properties right! I am using java.util.Properties, but it isn't working! I just want a really simple way to store variables, hich I usually do with properties, but this time it isn't working. Here is the SSCEE (I think thats the right way you name it)

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.Properties;
 
public class SSCEE 
{
	public static void main(String[] args) throws Exception
	{
		Properties prop = new Properties();
		File f = new File(System.getProperty("user.home")+"/DogWalking/user-info/user.properties");
		FileOutputStream out = null;
		FileInputStream in = null;
		if(!f.exists())
		{ //Creates and sets defaults fine...
			new File(System.getProperty("user.home")+"/DogWalking/user-info/").mkdirs(); //Create directory
			f.createNewFile();//Create file
			in = new FileInputStream(f);
			out = new FileOutputStream(f);
			System.out.println("Created a new user.properties! Setting default values");
			prop.setProperty("timeWalked", "0");
			prop.setProperty("moneyGained", "0");
			prop.store(out, "--No Comment--");
			out.flush();
			out.close();
			prop.load(in);
			in.close();
			System.out.println(prop);
		}else if(f.exists())
		{ //Finds nothing
			in = new FileInputStream(f);
			out = new FileOutputStream(f);
			System.out.println("Found a user.properties! Getting values!");
			prop.load(in);
			in.close();
			if(prop.containsKey("timeWalked") && prop.containsKey("moneyGained"))
			{
				System.out.println("Success!");
				System.out.println(prop);
			}else
				System.out.println("Fail! " + prop); //Every time goes here.
			prop.store(out, "--No Comment--"); //Just Checking for debugging purposes exactly what it does... and it prints nothing!
			out.flush();
			out.close();
		}
	}
}

All help is appreciated.

The first run it prints

Created a new user.properties! Setting default values
{moneyGained=0, timeWalked=0}

And the file looks like

#--No Comment--

moneyGained=0
timeWalked=0

The second run (and all following) prints

Found a user.properties! Getting values!
Fail! {}

and the file looks like

Thanks for any help!
