Things are a little confusing under the hood of
java.io.File. Since they use a method named resolve
which does not resolve ../ and ./.

The same confusion is under the hood of java.nio.file.Path,
the method named resolve does also not resolve ../ and
./. Here you have to use the method normalize.

So the solution with path would be:

public class State {
     private static String curdir;

     public void chDir(String str) {
         curdir = Paths.getPath(curdir).resolve(str).normalize();
     }

}
