question: public static String pathToString ( String dim , String [ ] path ) { String [ ] fullPath = new String [ 1 + path . length ] ; fullPath [ 0 ] = dim ; System . arraycopy ( path , 0 , fullPath , 1 , path . length ) ; return pathToString ( fullPath , fullPath . length ) ; }
target:  Turns a dim + path into an encoded string.
