步骤1:准备InputStream流和本地文件路径 首先,你需要准备一个InputStream流和一个本地文件路径。下面是代码示例: // 本地文件路径StringfilePath="path/to/your/file.txt";// 创建InputStream流InputStreaminputStream=newFileInputStream("path/to/your/input/file.txt"); 1. 2. 3. 4. 步骤2:创建OutputStr...
读取InputStream中的数据,并使用FileOutputStream写入到文件。 关闭两个流以释放资源。 3. 代码示例 下面是一个简单的Java代码示例,演示如何将InputStream中的数据输出到一个文件: importjava.io.FileInputStream;importjava.io.FileOutputStream;importjava.io.IOException;publicclassInputStreamToFile{publicstaticvoidmai...
Note that in this example, the input stream has known and pre-determined data, such as a file on disk or an in-memory stream. As a result,we don’t need to do any bounds checkingand we can, if memory allows, simply read it and write it in one go. If the input stream is linked...
*将InputStream写入本地文件 * @param destination 写入本地目录 * @param input 输入流 * @throws IOException */ privatestaticvoidwriteToLocal(String destination, InputStream input) throwsIOException { intindex; byte[] bytes =newbyte[1024]; FileOutputStream downloadFile =newFileOutputStream(destination)...
bufferWritter.write(data); bufferWritter.close(); System.out.println("Done"); }catch(IOException e){ e.printStackTrace(); } } } 结果 现在,文本文件“javaio-appendfile.txt”内容更新如下: ABC Hello This content will append to the end of the file ...

"file-new.xml");int bytesWritten = 0;int byteCount = 0;byte[] bytes = new byte[1024];while ((byteCount = inputStream.read(bytes)) != -1){outputStream.write(bytes, bytesWritten, byteCount);bytesWritten += byteCount;}inputStream.close();outputStream.close();
如果不使用nio那就是：public void convertInputStreamToFile(InputStream inputStream, String filePath) ...
