7File file = new File("test.txt");
InputStream input = new FileInputStream(file);
byte[] byt = new byte[input.available()];
input.read(byt); -
将byte数组转换为InputStream:
1
2
3byte[] byt = new byte[1024];
InputStream input = new ByteArrayInputStream(byt); -
将byte数组转换为File :
1
2
3
4

7File file = new File('');
OutputStream output = new FileOutputStream(file);
BufferedOutputStream bufferedOutput = new BufferedOutputStream(output);
bufferedOutput.write(byt);
