java读取txt文件
public static void readTxtFileByFileUtils(String fileName) { File file = new File(fileName); LineIterator lineIterator = null; List list = null; try { /*//一次读取全部内容 List lines = FileUtils.readLines(file, "UTF-8"); System.out.println(lines);*/ lineIterator = FileUtils.lineIterator(file, "UTF-8"); list = new ArrayList(); int lineNum = 0; while (lineIterator.hasNext()) { String line = lineIterator.nextLine(); // 行数据转换成数组 String[] custArray = line.split("\\|"); list.add(custArray); lineNum++; System.out.println("---" + lineNum); if (lineNum % 1000 ==0) { Thread.sleep(10); } } } catch (IOException e) { e.printStackTrace(); } catch (InterruptedException e) { e.printStackTrace(); } finally { if (lineIterator != null) { LineIterator.closeQuietly(lineIterator); } } if (list != null) { for (int i = 0; i < list.size(); i++) { String[] s = (String[]) list.get(i); for (int j = 0; j < s.length; j++) { System.out.println(s[j]); } } } }
