Path,files Consolidation, Title: Receive two folder paths from the keyboard, copy one of the folders (containing content) to another folder

This topic with the traditional file,inputstream can do, but if the Files,path class to do, although the idea will be difficult, but the code is a lot more concise, the following is the code:

Importjava.io.IOException;ImportJava.nio.file.FileVisitResult;ImportJava.nio.file.Files;ImportJava.nio.file.Path;Importjava.nio.file.Paths;ImportJava.nio.file.SimpleFileVisitor;Importjava.nio.file.attribute.BasicFileAttributes;ImportJava.util.Scanner;//receive two folder paths from the keyboard, copy one of the folders (containing content) to another folder Public classDemo1 { Public Static voidMain (string[] args)throwsIOException {Path path1=getpath ();//Get source folder pathPath Path2=getpath ();//Get destination Folder pathPath Path=path1.getfilename ();//gets the last filename of the source filePath2=path2.resolve (path);//Create a folder to store the contents of the source file in the destination filecopy (path1,path2); }     Public Static voidCopy (path path1, path path2)throwsIOException {files.walkfiletree (path1,NewSimplefilevisitor<path>() {            //actions to take before accessing the folder@Override PublicFilevisitresult previsitdirectory (Path dir, basicfileattributes attrs)throwsIOException {Path P1=path1.relativize (dir);//Get folder relative pathPath P2=path2.resolve (p1);//create a path in the destination folderFiles.createdirectories (p2);//Create a folder.                returnFilevisitresult.continue;//continue to access.} @Override PublicFilevisitresult visitfile (Path file, Basicfileattributes attrs)throwsIOException {Path P1=path1.relativize (file);//gets the relative path of the file relative to the source filePath P2=path2.resolve (p1);//get the path location of the file in the destination fileFiles.copy (file, p2);//copying files using the copy function of the files class                returnFilevisitresult.continue;//continue to access.} @Override PublicFilevisitresult visitfilefailed (Path file, IOException exc)throwsIOException {returnFilevisitresult.continue;//access failed, continue access.            }                     }); }     Public StaticPath GetPath () {System.out.println ("Please enter a folder!"); String Str=NULL; Scanner SC=NewScanner (system.in); STR=Sc.nextline (); Path Path=paths.get (str);//Get Path        if(!files.exists (path)) {System.out.println ("Please enter a folder that exists");        GetPath (); }        if(Files.isregularfile (path)) {System.out.println ("Please enter the file!");        GetPath (); }        returnpath; }}
