I want to have an InputStream in a class like this:
class A {
InputStream inputStream = ...
}
And I want to write to that InputStream using a OutputStream from another class which is in the same application. Is it possible to do this?

Take a Look at PipedInputStream and PipedOutputStreamFelix– Felix2020-10-22 19:06:14 +00:00Commented Oct 22, 2020 at 19:06

Yes it is! PipedOutputStream (see) and a PipedInputStream (see) is what you need.
Here is a little example how to use it:
public static void main(String[] args) throws ParseException, IOException {
PipedInputStream inputStream = new PipedInputStream();
PipedOutputStream outputStream = new PipedOutputStream(inputStream);
// Write some data to the output stream
writeDataToOutputStream(outputStream);
// Now read that data
Scanner src = new Scanner(inputStream);
System.out.println(src.nextLine());
}
private static void writeDataToOutputStream(OutputStream outputStream) throws IOException {
outputStream.write("Hello!\n".getBytes());
}
The code will output:
Hello!
