A few notes. You may need to do some things as root (the admin user). In order to become root (not groot - even though i know we are all watching infinity wars at the start of class) you can type su - root into the console and enter your password. I would make sure you have a snapshot done before you do this. Become root and do the following 2 commands in your terminal in the VM apt update apt upgrade -y These commands will update your system and may be needed to ensure you have completely up to date packages and software A note on making the hello-1.c Add the following line of code at the end, it will fix the issues we were having last night.

- In Java, what is the difference between a checked exception and an unchecked exception? A. A checked exception is one that is handled in a try-catch block. An unchecked exception is one that is declared via the throws keyword in the method signature B. An unchecked exception is an exception like a NullPointerException which we do not anticipate. However, exceptions we can anticipate, like NumberFormatException when using Integer.parselnt, are checked Exceptions C. An unchecked exception is one that is handled in a try-catch block. A checked exception is one that is declared via the throws keyword in the method signature D. Java syntactically forces you to handle checked exceptions, or use throws to declare the function is capable of throwing a checked exception Reset SelectionSuppose you have Java source files under the directorieschapter1, chapter2, . . . , chapter34.
