1、将File、FileInputStream 转换为byte数组:
File file = new File("test.txt");
InputStream input = new FileInputStream(file);
byte[] byt = new byte[input.available()];
input.read(byt);
2、将byte数组转换为InputStream:
byte[] byt = new byte[1024];
InputStream input = new ByteArrayInputStream(byt);
3、将byte数组转换为File:
File file = new File(‘‘);
OutputStream output = new FileOutputStream(file);
BufferedOutputStream bufferedOutput = new BufferedOutputStream(output);
bufferedOutput.write(byt);
java 中 byte[]、File、InputStream 互相转换
