FileInputStream和FileOutputStream都属于文件字节流。 通常我们可以用来做文件的复制操作,如下: 1 import java.io.File; 2 import java.io.FileInputStream; 3 import java.io.FileOutputStream; 4 5 public class Main { 6 7 public static void main(String[] args) { 8 readFile(); 9 } 10 public ...

File inputFile = new File(inputFileName); FileInputStream in = new FileInputStream(inputFile); byte bt[] = new byte[(int)inputFile.length()]; in.read(bt); s = new String(bt); in.close(); }catch(java.io.IOException e){
最后,我们返回了这个临时文件对象。 使用此方法可以方便地处理从InputStream到File的转换需求。希望这篇文章对你有所帮助! 引用链接: [Oracle官方文档:File类]( [Oracle官方文档:BufferedInputStream类]( [Oracle官方文档:BufferedOutputStream类](
