已经对读取的文经过处理,现在想把它存入另一个一个文,应该用什么命令,请各位大侠帮忙!

Question

会读怎么就不会写呢？
其实是一样的,不就是吧Reader改为Writer吗？

Answer 1

FileWriter fOut = null;
                try 
                {
                    fOut = new FileWriter(file);
                    String fileContent = "文件内容";
                    fOut.write(fileContent);   
                    fOut.close();
                    fOut = null;
                } 
                catch (FileNotFoundException e1) 
                {
                    e1.printStackTrace();
                }
                catch(IOException eIO)
                {
                    eIO.printStackTrace();
                }                
                finally
                {
                    if (null != fOut)
                    {
                        try {
                            fOut.close();
                        } catch (IOException e2) {
                            // TODO Auto-generated catch block
                            e2.printStackTrace();
                        }
                    }
                }
