在Java中,InputStream是所有输入流的基类,提供了基本的读取操作,而FileInputStream是InputStream的子类,专门用于从文件中读取数据。由于FileInputStream是InputStream的特化,直接将一个任意的InputStream对象转换为FileInputStream对象在逻辑上是不成立的,除非这个InputStream对象本身就是FileInputStream的实例。 然而,如果你的...

如果不使用nio那就是：public void convertInputStreamToFile(InputStream inputStream, String filePath) ...
outStream.write(buffer,0, bytesRead); } }catch(Exception e) { e.printStackTrace(); } 另一种实现方式: try(InputStream initialStream =newFileInputStream(newFile("src/main/resources/sample.txt"))) { File targetFile=newFile("src/main/resources/targetFile.tmp"); ...

可以通过以下方法将InputStream转换为File: import java.io.*; public class Main { public static void main(String[] args) { InputStream inputStream = null; FileOutputStream fileOutputStream = null; try { inputStream = new FileInputStream("input.txt"); File file = new File("output.txt"); ...
