用list吧,数组你提前知道多大吗?不然会越界的!
FileReader fr = null; BufferedReader br = null; List<String> nameList = new ArrayList<String>(); List<String> phoneList = new ArrayList<String>(); try { fr = new FileReader(new File("H:\test.txt")); br = new BufferedReader(fr); String line = null; String[] strs = null; while ((line = br.readLine()) != null) { strs = line.split("\s+"); nameList.add(strs[0]); phoneList.add(strs[1]); } } catch (Exception e) { e.printStackTrace(); } finally { if (br != null) { try { br.close(); } catch (IOException e) { e.printStackTrace(); } } if (fr != null) { try { fr.close(); } catch (IOException e) { e.printStackTrace(); } } } |
