Question

I need to read in a Properties object from a file, however I need to switch the key and value pairs around, i.e. I need the keys to become the property values and vice-versa. I also cannot just change this on the file I am reading in. Any ideas how I could do this?

Thanks

You can create a second Properties object, iterate over the entires you have just read, calling put(entry.getValue(), entry.getKey()) and you have it.
