ZCW-Fido-URLFetch

write a simple program that fetches a URL.

There is a Linux/Unic/Mac commandline tool named curl. It Fetches a url and prints it to the terminal output.

Write a simple tool `fido` that takes an argument from the commandline, and fetches the page at that address, printing it to standard out. (The terminal)

In InteeliJ, you will need to look for a Java library that can let you get the contents of a page from a given URL. There are several. Pick one that allows you to add it to the pom.xml file to get the library linked into your project.

Examples

fido https://google.com/zipcodewilmington

returns a page something like:
