How can we read or use the contents of outputstream [closed]

Question

How can we read or use the contents of outputstream. In my case, I am using a method having signature.

public static OutputStream decryptAsStream(InputStream inputStream, String encryptionKey)

This method return OutputStream. I want get OutputStream to String. Is it possible to pipe the output from an java.io.OutputStream to a String in Java?

Answer 1

You can do something like following :

  OutputStream output = new OutputStream()
    {
        private StringBuilder string = new StringBuilder();
        @Override
        public void write(int x) throws IOException {
            this.string.append((char) x );
        }

        public String toString(){
            return this.string.toString();
        }
    };
