The following code is intended to test whether the int variable num is less than 10, and if so print a warning and set it to 10. The code then prints the value of num. if (num < 10)
System.out.println( "This is smaller than 10" );
num = 10;
System.out.println("Value of num is " + num);
What correction should be made so the code functions as intended?

An else statement should be added between the 3rd and 4th lines
The final line should be printed every time, not just when num hasn’t been changed.
A semicolon should be added at the end of the first line
The operator ‘<’ should be changed to ‘<=’ in the if statement
No correction should be made
Curly braces ‘{ }‘ should be added to enclose the second and third lines

The only correction I see is you need to add curly braces to enclose the second and third lines.

Hey there! Hello!

I'm certainly not an expert at anything related to ethernet, but I do believe that the answer you're looking for is a jam signal. To my limited understanding, CSMA/CD makes computers "listen" before sending data to see if their signal is currently being used. If it's not, it'll send. The computer and sender will continue to "listen" to see if a jam still occurred afterwards. If one did occur, a jam signal will be sent to everyone who may send something over that signal, warning them not to send anything else, since it will not be successful and may make the jam worse. 

Hope this helped you out! I would normally tell the question–askers that they can ask me any additional questions they may have, but... that's the extent that I know about ethernet, haha! :-)
