What the heck?! Stuck on validating last requirement

Question about the task

Extending AmigoOutputStream

Java Core, Level 8, Lesson 8

Resolved

I need help.... today i got already 3 tasks on which i'm stuck at validation while my code seems to work just fine...

Using the wrapper (decorator) design pattern, extend the functionality of AmigoOutputStream.
In the QuestionFileOutputStream class, the following functionality should be implemented for the close() method:
1. Display "Do you really want to close the stream? Y/N".
2. Read a line.
3. If the read line is "Y", then close the stream.
4. If the read line is not "Y", then don't close the stream.

Requirements:

Don't change AmigoOutputStream.
The QuestionFileOutputStream class must implement the AmigoOutputStream interface.
The QuestionFileOutputStream class must initialize the AmigoOutputStream field in the constructor.
All of QuestionFileOutputStream's methods must be delegated to the AmigoOutputStream object.
The close() method should ask the user, "Do you really want to close the stream? Y/N".
The close() method should close the stream only if it reads the answer "Y" from the console.

package com.codegym.task.task18.task1812; import java.io.IOException; public interface AmigoOutputStream { void flush() throws IOException; void write(int b) throws IOException; void write(byte[] b) throws IOException; void write(byte[] b, int off, int len) throws IOException; void close() throws IOException; }

We all do. I had a task just recently I failed 45 times before asking for help and the problem was one of my methods in one of the 16 some odd classes in the greater task had a protected modifier instead of a public. some tasks just have you banging your head on the keyboard.

Haha yeah when tasks get bigger the smaller mistakes are much harder to find. Well this one was quite silly. It already didnt make sense that i needed to open a stream and close it in the same method ))

I don't understand, my code looks exactly like this and I got the same result. After checking your answer I closed the ' private AmigoOutputStream variable ' and it passed , but how is the variable a stream?

Yes, same for me! First I thought I need to close the BufferedReader but it wouldn't validate. Then, in the solution it says to close the AmigoOutputStream... why ???
