How to write a to a text file afer you parse it?
Please take a look at my original question.
Hi all, I have a file call default.cfg , it is actually a simple text file with the following format:
#define ContactSurname=William
#define ContactGiven=Bob
#define ContactPhone=1234567890
#define ContactExt=123
#define EntityName=secret101
#define Street=12 street
#define City=San Francisco
#define Country=USA
#define Zip=123456
and so on and so on.
My question is, how could I create a java program to parse these values such that I could call
return findValue("ContactSurname"
This one is answered at the link below:
https://www.experts-exchange.com/questions/21823634/How-can-I-parse-a-text-file.html
My next question is what if I like to change the value say return setValue("ContactSurname",
#define ContactSurname=William changes to #define ContactSurname=Henry
I have tried serveral methods on my own but it seems my program just delete all the text and save as a blank file :(

Hehe, I agree, I told him to look into property files on the link he listed above. In fact I posted the exact link that you have along with the java API docs on Properties.
It does everything that he wants to do and all the code is already there.
Hopefully fylix is starting to agree. No need to reinvent the wheel =)

I don't see why this Q was asked ;-)

flyix hopefully you are going to use Properties files now.
Follow the links we provided to get some quick sample code that should be enough to get you used to using Properties files. They are really easy to work with.

I actually kinda twiched your code abit and got what I wanted.
The thing is my txt file may not be in this format ( #define ) though out them, it may have some token or other line added in, your code seems to let me declare any unexpected but yes , i will take your advice and see if I can translate these using properties, Thanks again Joe.

No problem, cya round! =)
>> #define
Remember that # and ! define comments in properties files, so those lines will not be read.

No need to have #define there. Just use:
ContactSurname = William
so on and so forth. # is a comment in a properties-file
