How To Use an INI File (Properties)

Java How To: Source Code

[INI file : user.ini] DBuser=anonymous

DBpassword=&8djsx
DBlocation=bigone

[JAVA code]

import java.util.*;
import java.io.*;

class readIni 
{
	public static void main(String args[]) 
	{
		readIni ini = new readIni();
		ini.doit();
	}

	public void doit() 
	{
		try
		{
			Properties p = new Properties();
			p.load(new FileInputStream("user.ini"));
			System.out.println("user = " + p.getProperty("DBuser"));
			System.out.println("password = " + p.getProperty("DBpassword"));
			System.out.println("location = " + p.getProperty("DBlocation"));
			p.list(System.out);
		}
		catch (Exception e) 
		{
			System.out.println(e);
		}
	}
}

Since the Properties class extends the Hashtable, we can manipulate the Properties through the get and put methods. The modified data can be saved back to a file with the store method. This can be useful to store user prefenrences for example.

import java.util.*;
import java.io.*;

class WriteIni 
{
	public static void main(String args[]) 
	{
		WriteIni ini = new WriteIni();
		ini.doit();
	}

	public void doit() 
	{
		try
		{
			Properties p = new Properties();
			p.load(new FileInputStream("user.ini"));
			p.list(System.out);

			// new Property
			p.put("today", new Date().toString());

			// modify a Property
			p.put("DBpassword","foo");

			FileOutputStream out = new FileOutputStream("user.ini");
			p.store(out, "/* properties updated */");
		}
		catch (Exception e) 
		{
			System.out.println(e);
		}
	}
}

This ok with an application but you can't do it from an Applet since you can't write directly on the server without some kind of a server-side process.

To read an ini file via an Applet, the Properties class is still useful. Just load the Properties this way :

p.load((new URL(getCodeBase(), "user.ini")).openStream());

An INI file (or Properties) in a JAR can be used this way :

URL url = ClassLoader.getSystemResource("/com/rgagnon/config/system.ini");
  if (url != null) props.load(url.openStream());
