Getting information through an API

Java Syntax, Level 16, Lesson 7

Under discussion

Your task is to access a public API on the Internet to send and receive data.
Write a program that uses a URL for a public web API to send data and then receive a response and display it on the screen.

Hints:

Use the openConnection() method of the URL class.
Use the setDoOutput(true) and getOutputStream() methods of the URLConnection class.
If you don't know which API to use, use http://httpbin.org/post.

Requirements:

The program should display the received information on the screen.
The program should call the openConnection() method of the URL class.
The setDoOutput(true), getOutputStream(), and getInputStream() methods of the URLConnection class must be called in the program.
