I don't understand my java errors

Here is my workspace snapshot: https://w.trhou.se/95m0sk7ahf

I run this command: 

clear && javac Hangman.java && java Hangman

and I get these errors in the console:

It may sound silly, but when you get an error like this (and don't have an IDE to help you) one thing you can do is count out open and closed brackets on your fingers.

For each open bracket, put a finger up, for each closing bracket put a finger down. If you aren't looking at a closed fist by the time you're done counting, then something's gone wrong.

*The question is obviously long solved, but just general info for anyone else seeing a wall of strange errors like this.
