Java Files question

[Kudzė]

Hello guys so i create my YamlConfiguration (Its going to save data when i turn off application) but I'm currently stuck ;D How its possible to write and read in yml file I have this code (It creates and makes folders fine ;D but I'm stuck in how to read and write to the file ;D):

package com.mygdx.game.Files; import java.io.File;import java.io.IOException; public class YamlConfiguration { File FILE;File Folders = new File(FILE.getPath().replace(FILE.getName(),"")); public YamlConfiguration(File file) {FILE = file;} public void save() throws IOException {if(!Folders.exists()) mkdirs();try {FILE.createNewFile();} catch(IOException e) {throw e;}FILE.setReadable(true);FILE.setWritable(true);} public void mkdirs() {Folders.mkdirs();} public void saveInt(String key, int value) {//HowToDoThis? :DDD}  }

Thanks! Its Okay, I think its time for google to give me some examples ;p If this post won't be marked solved when u go on pc post an example ok?

 

EDIT: 

I think i found a way to do it But I need example to see how you did ok?

okay i am on PC for a while here but question: are you trying to store configuration data for a program? if so then i am going to very very very strongly recommend you use the Properties classes. i will dig through my code and find somewhere where i used BufferedWriters or i will make an example since they are fairly easy for me. but i will also put up an example of using the properties stuff because it is immensely useful. you ever messed with minecraft server properties? that uses java properties stuff

that is for using the Properties stuff

PrintWriter demo, similar to BufferedWriter but little less explicit for when data is flushed

import java.io.*;/** * Created by James on 12/2/2015. */public class BufferedWriterDemo{    public static void main(String[] args)    {        //do stuff in here        try        {            /*            BufferedWriters are great for maintaining control over the output of the file and when            data is actually written (either to the network or to the disk)             */            BufferedWriter writer = new BufferedWriter(new FileWriter(new File("./foo.txt")));            writer.write("this is a line");            writer.flush();            writer.close();        }        catch(IOException ioe)        {            ioe.printStackTrace();        }    }}

BufferedWriter demo. these are useful for when you want to explicity control when the data is written to the file. but i would say go for PrintWriter or the Properties utility.

Thanks man I,m at the school at the moment when i go back to my computer i'm gonna test it but as far as i read i understand all of you but only one thing isnt clear how to read from properties file? ;D

read over the properties demo, you will see how i read the file into the program and then access the property "TEXT"

Yea ok thanks i found it ;D I did a bit copy paste to test it but It doesn't work ok so there is my system.out

-snip-

when you catch the error, trying doing a stacktrace printout so we can walk through what is specifically happening. if you have hangouts it would be better for communication as it is a little faster
