kotlin read all bytes from inputstream

To read all bytes from an InputStream in Kotlin, you can use the following steps:

1. Create an instance of the InputStream class: kotlin val inputStream: InputStream = // initialize the input stream

2. Create a buffer with a fixed size to hold the bytes: kotlin val bufferSize = 1024 // choose an appropriate buffer size val buffer = ByteArray(bufferSize)

3. Create a ByteArrayOutputStream to store the bytes read from the input stream: kotlin val outputStream = ByteArrayOutputStream()

4. Read the bytes from the input stream in a loop until the end of the stream is reached: kotlin var bytesRead: Int while (inputStream.read(buffer).also { bytesRead = it } != -1) { outputStream.write(buffer, 0, bytesRead) }

5. Close the input stream to release system resources: kotlin inputStream.close()

6. Retrieve the byte array from the ByteArrayOutputStream: kotlin val byteArray = outputStream.toByteArray()

Now, you have successfully read all bytes from the input stream and stored them in a byte array.
