Answer 1

放到main方法里运行

File file=new File("E:/book.txt");
            OutputStreamWriter osw = null;
            if(file.exists()){
                try {
                    file.createNewFile();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            try {
                osw=new OutputStreamWriter(new FileOutputStream(file));
                osw.write("Made in China");
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }finally {
                try {
                    osw.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
