优雅写Java之三(IO与文本解析)
一、资源相关
二、路径与文件
读文件:
String fileName = "str.txt";
Files.lines(Paths.get(fileName), StandardCharsets.UTF_8).forEach(System.out::println);
List<String> out = Files.readAllLines(Paths.get(fileName));
// 按行读
private static void readFile(String fileName) throws IOException {
BufferedReader br = new BufferedReader(new FileReader(new File(fileName)));
String line;
Set<String> readOnlyPath = new TreeSet<>();
Set<String> otherPath= new TreeSet<>();
while ((line = br.readLine()) != null) {
System.out.println(line);
getOpenPathList(line, readOnlyPath, otherPath);
}
br.close();
}
写文件:
Files.write(Paths.get("output1.txt"), content.getBytes());
三、数据解析
