1. Path使用

   • 构造Path对象

     Path path1 = Paths.get("C:/", "Xmp");Path path2 = Paths.get("C:/Xmp");

   • File和Path之间的转换

     File file = new File("C:/my.ini");Path p1 = file.toPath();File file = p1.toFile();

   • 创建文件

     Path p = Paths.get("C:\\mystuff.txt");if (!Files.exists(p)) {    try {        Files.createFile(p);    } catch (IOException e) {        e.printStackTrace();    }}

   • 读取文件

     Path p = Paths.get("C:\\mystuff.txt");try {    BufferedReader reader = Files.newBufferedReader(p);    String line = null;    while ((line = reader.readLine()) != null) {        System.out.println(line);    }} catch (IOException e) {    e.printStackTrace();}

   • 写入文件

     Path p = Paths.get("C:\\mystuff.txt");try {    BufferedWriter writer = Files.newBufferedWriter(p);    writer.write("hello");    writer.write("world");    writer.flush();    writer.close();} catch (IOException e) {    e.printStackTrace();}
