Open and edit a file in .jar using Java?

Question

How would you start to open the XML file that is inside the .jar and edit it?

I know you can ...

InputStream myStream = this.getClass().getResourceAsStream("xmlData.xml");

But how would you open xmlData.xml, edit the file and save it in .jar? I would find it useful to know and don’t want to edit the file outside of .jar ... and the application should remain functional all the time!

Thank!

Answer 1

Jar files are just .zip files with different file suffixes and a naming convention for content. Therefore, use classes from java.util.zipto read and / or write content.
