want to try out small idea; where is the implementing class for Stream interface?

[Chen Liang]

Hi Anil,
Ant is not a command-line tool of linux; it's an ancient Java build tool
popular 10 years ago, before the appearance of Gradle. Its homepage is at
https://ant.apache.org/
Once you download, extract it, and add its bin directory to PATH, the
script will find ant automatically.
