如何将Typecast File对象转换为InputStream

Question

如何将File对象Typecast转换为InputStream.

File file=new File("c:\\abc.txt");

谢谢

Answer 1

        File file=new File("c:\\abc.txt");
    InputStream is = new FileInputStream(file);

要么

    InputStream is = new FileInputStream("c:\\abc.txt");

Answer 2

您没有将文件类型转换为输入流,您使用该文件作为参数创建一个InputStream对象.您可以使用FileInputStream:

FileInputStream fis = new FileInputStream(file);
