newInputStream(Paths.get("input.txt"))) { // convert stream to file Files.copy(stream, Paths.get("output.txt")); } catch (IOException ex) { ex.printStackTrace(); } The above code will throw an error if the file already exists. To replace the existing file, you can use the ...
要将InputStream转换成文件夹,我们需要先创建一个文件夹,然后将InputStream中的数据写入到该文件夹中。下面是一个简单的示例代码: importjava.io.*;publicclassInputStreamToFile{publicstaticvoidconvert(InputStreaminputStream,StringfolderPath){Filefolder=newFile(folderPath);if(!folder.exists()){folder.mkdirs()...

In the example above,we create aBufferedReaderobject wrapped around theInputStreamusing anInputStreamReader. This allows us to read lines of text efficiently from theInputStream.Additionally, thelines()method of theBufferedReaderreturns aStream<String>containing the lines read from the input. Lastly,...
Java Program to Convert InputStream to String 读取和写入操作是用户在任何应用程序中执行的基本功能。每种编程语言都提供 I/O 流来读取和写入数据。 Java 的 FileInputStream 类和 FileOutputStream 类对文件进行 I/O 操作。 FileInputStream 类用于从文件中读取数据,FileOutputStream 类用于将数据写入文件。有几...
