Hi all.

I want to read and update a ini file to do some processing. Here is what I have try.

Code:
public static void main(String[] args) {
        // TODO code application logic here
        new ReadINIFile().readIt();
        //new ReadINIFile().writeIt();
    }
    
    private void readIt() {
        try {
            Properties pro = new Properties();
            pro.load(new FileInputStream("temp.ini"));
            
        // Try to display them          
            System.out.println("Key is: " + pro.getProperty("Key"));            
            System.out.println("Here is: " + pro.getProperty("Here"));
            
        }
        catch(Exception ex) {
            System.out.println(ex.getMessage());
        }
    }
    
    private void writeIt() {
        // Try to update values
        try {
            Properties pri = new Properties();
            pri.store(new FileOutputStream("temp.ini"), "Just a comment");
            pri.setProperty("Here", "New");
            
        }
        catch(IOException ioe) {
            System.out.println(ioe.getMessage());
        }
    }
Reading part is ok, it's read all data I want. When I write all content of the ini file is deleted and following is the content.

Can anyone of you tell me where I'm going wrong. Here is the structure of the ini file.

[Head]
Text=Java
Key=14
Name=Old
[More]
Here=New
