Write to a file

[Donasio]

I want to write a file in linux

for windows I use
FileWriter airFile = new FileWriter("c:\\Asthma_Data\\zip.xml");

what path would I use for linux?
should I start from root
e.g

FileWriter airFile = new FileWriter("root\\Asthma_Data\\zip.xml");

If your Asthma_Data folder is present inside opt then
FileWriter airFile = new FileWriter("/opt/Asthma_Data/zip.xml");

what about root????
shouldnt it be
FileWriter airFile = new FileWriter("/opt/Asthma_Data/zip.xml");

It is good practice to avoid using the root user, if possible.

In general:
If that Asthma_Data/zip.xml is your personal data, it belongs in your home directory.
If data needs to be shared locally or remote, then I tend to create datadirectories like /data1, /data2, etc and bindmount directories in them to /data
