Java读写记事本文件

Java中我们也会考虑读写记事本,文件读取如下:

public static void main(String[] args) {
        try {
            String path="d:\abc.txt";//定义文件路径名称
            //文件输入流
            FileInputStream fs= new FileInputStream(path);
            //内存输入流
            InputStreamReader is=new InputStreamReader(fs);
            BufferedReader br=new BufferedReader(is);
            String line=br.readLine();            
            while(line!=null){
                System.out.println(line);
                line=br.readLine();
            }
            
            //释放资源
            br.close();
            is.close();
            fs.close();            
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

 文件写入如下:

public static void main(String[] args) {
        try {
            String path="d:\duanjt.txt";
            String str= System.getProperty("line.separator");//换行符
            String reout="duanjt"+str+"中华人民共和国"+str+"第三行";
            FileOutputStream fos=new FileOutputStream(path);            
            fos.write(reout.getBytes());
            fos.close();
            System.out.println("文件写入成功");
            
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

多的就不说了,代码比较简单,清晰明了
