-**JPX** is a Java library for creating, reading and writing [GPS](https://en.wikipedia.org/wiki/Global_Positioning_System) data in [GPX](https://en.wikipedia.org/wiki/GPS_Exchange_Format) format. It is a *full* implementation of version [1.1](http://www.topografix.com/GPX/1/1/) and version [1.0](http://www.topografix.com/gpx_manual.asp) of the GPX format. The data classes are completely immutable and allows a functional programming style. They are working also nicely with the Java [Stream](https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/stream/Stream.html) API. It is also possible to convert the location information into strings which are compatible to the [ISO 6709](http://en.wikipedia.org/wiki/ISO_6709) standard.

 Besides the basic functionality of reading and writing GPX files, the library also allows manipulating the read GPX object in a functional way.
 
 
 ## Dependencies
 
-The _JPX_ library needs no external dependencies. It only needs **Java 17** to compile and run. It also runs and compiles with **Java 21** and **Java 23**.
