Great, thank U.

The problem with this code is that the streams are not closed after the properties are read or written

thanks !!!
clear and useful

Спасибо за уроки брат.

Properties prop = new Properties();

try {
FileInputStream fis = new FileInputStream("yourPropertiesFile.properties");
prop.load(fis);
// You can do something here like getting the value of a key. Example
String str = prop.getProperty("yourKey");
System.out.println(str);

fis.close();

FileOutputStream fos = null;
// Setting a key=value pair
prop.setProperty("yourKey", "theValue");
prop.store((fos = new FileOutputStream("yourPropertiesFile.properties")), "Author: jasonX");
} catch(IOException e) {
e.printStackTrace();
}

thx for the example. helpful

GREAT EXAMPLE

properties.store(new FileOutputStream("C:/ibm_scopedb_en.pl"), "1.comment"+"\n"+"2.comment");
how to write the commnet in new line ?

CORRECTED:
Properties properties = new Properties();
InputStream is = null;
try {
is = new FileInputStream( "filename.properties" );
properties.load( is );
} catch( IOException e ) {
// ...
} finally {
if( null != is ) try { is.close(); } catch( IOException e ) { /* .... */ }
}

i tried this. but nothig happended. my file.properties wasn't modificated.

Properties prop = new Properties();
try {

FileOutputStream fileOutputStream = null;
prop.setProperty("-----", "----");
prop.store((fileOutputStream = new FileOutputStream(getClass().getResource("/resources/prueba.properties").getPath())),null);
fileOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}

I am getting this error on prop.load(in). Can you help.

Properties prop = new Properties();

FileInputStream in = new FileInputStream("C://user.properties.txt"); prop.load(in);

Multiple markers at this line
- Syntax error on token(s), misplaced construct(s)
- Syntax error on token "in", VariableDeclaratorId expected after
this token

I think you should use C:\\user.properties.txt i.e BACKSLASH instead of FORWARD SLASH

I've found the solution for my problem.

Thanks, the example helped me a lot.

this looks difficult, think ill give up! www.callaways.co.uk

[cdoe]
Properties props = new Properties();
props.load(getClass().getResourceAsStream("message.properties"));
[/code]

This will load message.properties file just on the same folder as the main java file.

Is there a way to insert a comment inside the value of a property?
I mean something like:
propname=value #and this is a comment

this doesn't work for me, all the line after the "=" is considered as part of the value

Great post. I'm subscribing now for future reads.

when i am using property file in web application it is throwing null pointer exception
but that is working in normal java

You make some good points. I like your point of view.M

You make some good points. I like your point of view.

What about if I don't want server to restart when I change some property file value.
I am using Tomcat as server and we have GUI and I need when user change any property file value.. that should be reflected without restarting the server..

Any solution for this prob.

I received 1 st personal loans when I was not very old and that supported me a lot. Nevertheless, I need the bank loan once again.

Thanks bro.. :)

HI

I have learned a lot from sites like this. In fact I don't depend on just books/classroom lectures. I would rather search for any examples for my tasks and test them right away and then modify again and again to suite my uses.

I will share my codes and applications like this manner and would love to share my experience with my community of java coders.

P.S. Please don't take bad comments seriously, if there are some codes not so good for anybody then they should find a good code and suggest in a positive way.

peace
