Java IO笔记
public static void main(String[] args) throws IOException {//输入流InputStream in = Test.class.getResourceAsStream("/test");InputStreamReader isr = new InputStreamReader(in);BufferedReader reader = new BufferedReader(isr);//输出流String resource = Test.class.getResource("/").toString();resource = resource.substring(5);File fw = new File(resource+"writer.txt");BufferedWriter writer = new BufferedWriter(new FileWriter(fw));int re;while((re = reader.read())!=-1){System.out.print((char)re);writer.write(re);}//刷新缓冲区，将缓冲区剩余的数据写入文件writer.flush();writer.close();isr.close();in.close();}?
