java 7中创建文件和目录

在java 7中,可以象下面那样创建文件和目录,用新的api咯

import java.io.IOException;
import java.nio.file.FileSystems;
import java.nio.file.Files;
import java.nio.file.Path;

public class FileCreation {
  public static void main(String[] args) {
    Path pathToDirectory = FileSystems.getDefault().getPath(
        "C:/Ablage/dev/workspace");
    try {
      Files.createDirectories(pathToDirectory);
      System.out
          .println("Directory created at path : " + pathToDirectory);
    } catch (IOException e) {
      e.printStackTrace();
    }
    Path pathToFile = FileSystems.getDefault().getPath(
        "C:/Ablage/dev/workspace/hello.pdf");
    try {
      Files.createFile(pathToFile);
      System.out.println("File created at path : " + pathToFile);
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

}
