java - HTTP request to obtain file output stream, how to convert it to file

Question

Excuse me, I send a request to return a file stream, field name: ouput type: ouputStream

jsonObject.get("ouput") gets the file stream, and the stream has data. How to convert it to the specified file?

Please help me, how to solve it

Answer 1

Converting to a specified file can be understood as reusing file to create a new file, and then using streams to operate on the file.
If so, you can use file and outputstream to write to file.
