/**
* PrintInternetRules.java
* Name: WongPuter
* Description: Displays student rules for accessing the Internet.
/*
public class PrintInternetRules
public static void main(String[] args) {
System.out.println("Internet Rules\n");
System.out.println("1. Use school issued login and password.");
System.out.println("2. Do not download any files.")
system.out.println("3. Do not reveal personal information.");
}
}- Date is missing in the comment block.
- Class name should be a noun.
- The opening brace bracket ({) of main method should line up with the closing brace bracket (}).
- System.out.println("Internet Rules\n"); should line up with the rest of System.out.println.

* Description: Displays student rules for accessing the Internet.
/*
public class PrintInternetRules
public static void main(String[] args) {
System.out.println("Internet Rules\n");
System.out.println("1. Use school issued login and password.");
System.out.println("2. Do not download any files.")
system.out.println("3. Do not reveal personal information.");
}
}ANSWER
- The comment block should be closed with */ but not /*.
- A brace bracket is missing after the class declaration.
- A ; is missing at the end of System.out.println("2. Do not download any files.")
- "system" should be typed as "System"
