Need example of properties file use

Question

I'm writing a text based adventure game to get some practice with the Java language. The only thing that's proving to be difficult is saving the game. I need an example of a class for basic properties operations. I've found various tutorials that all have some helpful information, but putting it all together isn't working for me. Here is what I have.
import java.io.BufferedWriter;
import java.io.FileWriter;
public class SaveGame{
public static void CreateSave(String name){//create the save file
    try{
        FileWriter fstream = new FileWriter(name+".properties");
        BufferedWriter out = new BufferedWriter(fstream);
        out.write("*-=Character Information=-*");
        out.write("name= \ngender= \n");
        out.write("*-=Basic Stats=-*");
        out.write("str= \nagl= \nend= \nchr= \nitl= \nlck= \n");
        out.close();
        }catch(Exception e){System.err.println("Error: " + e.getMessage());}
}//CreateSave
public static void SaveStatus/*save all variables to the file*/
(double str, double agl, double end, double chr, double itl,
  double lck, String name, char gender){
// I don't know how to edit values
}//SaveStatus
public static void ReadSave(){//reads the file and sends the variable back to main class
}//ReadSave
}//class The big thing is, I don't know how to edit the values in the properties file. I can handle reading them but i don't know how to convert the string values to int, double, etc. Thanks in advance.

Thanks for those.
Can you link to a decent tutorial on the properties class? Most of what I've found is a little more technical than I'm ready for, and they don't have examples.Suns own Java tutorial has some code snippets, that should get you going - [Properties tutorial|http://java.sun.com/docs/books/tutorial/essential/environment/properties.html]
