Java BufferedReader

问题:

I'm looking at this tutorial about BufferedReader at youtube

https://www.youtube.com/watch?v=yofFVbARIRU

I write the code exactly as he does but I can't get it to work. I cant get the BufferedReader code to work even though I imported it with

import java.io.*;

InputStreamReader stream = new InputStreamReader(System.in);
BufferedReader reader = new BufferedReader (stream);

I solved it with this code:

InputStreamReader stream = new InputStreamReader(System.in);
java.io.BufferedReader reader = new java.io.BufferedReader (stream);

And this works as well:

java.io.BufferedReader reader = 
new java.io.BufferedReader (new InputStreamReader(System.in));

Could someone explain to me what's wrong in the first code? Because it works for him who's giving the tutorial

You've likely got your own class that you've named BufferedReader and whose name is clashing with the core class and thus confusing the Java compiler. Rename it!
