下面是一个简单的示例代码,演示如何使用InputStream将数据写入文件: importjava.io.*;publicclassInputStreamToFile{publicstaticvoidmain(String[]args){try{InputStreaminputStream=newFileInputStream("input.txt");OutputStreamoutputStream=newFileOutputStream("output.txt");byte[]buffer=newbyte[1024];intbytesRead...
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...

Files.write(buffer, targetFile); 基于Commons IO的实现 InputStream initialStream = FileUtils.openInputStream(newFile("src/main/resources/sample.txt")); File targetFile=newFile("src/main/resources/targetFile.tmp"); FileUtils.copyInputStreamToFile(initialStream, targetFile); ...

FileInputStream输入流从文件中读取字节数据。 FileOutputStream输出流将字节数据写入文件。 BufferedInputStream输入流为字节输入流提供缓冲功能,提高读取效率。 BufferedOutputStream输出流为字节输出流提供缓冲功能,提高写入效率。 ByteArrayInputStream输入流将内存中的字节数组作为输入源。
