记录一些典型的Java代码。
一、文件读取
1 public class Test4 { 2 public static void main(String[] args) { 3 try { 4 FileReader fdFileReader=new FileReader("bitch.txt"); 5 BufferedReader bReader=new BufferedReader(fdFileReader); 6 String my=bReader.readLine(); 7 while (my!=null) { 8 System.out.println(my); 9 my=bReader.readLine(); 10 } 11 bReader.close(); 12 } catch (IOException e) { 13 // TODO: handle exception 14 System.out.println("找不到指定文件"); 15 } 16 } 17 }
二、文件写入
1 public class Test 2 { 3 public static void main(String[] args) 4 { 5 try { 6 String content = "Thank you for your fish."; 7 8 File file = new File("new.txt"); 9 10 // create the file if doesn‘t exists 11 if (!file.exists()) { 12 file.createNewFile(); 13 } 14 15 FileWriter fw = new FileWriter(file.getAbsoluteFile()); 16 BufferedWriter bw = new BufferedWriter(fw); 17 bw.write(content); 18 bw.close(); 19 20 } 21 catch(IOException e) { 22 System.out.println("IO Problem"); 23 } 24 } 25 }
