Scanning is the process of actively searching for and identifying active hosts, open ports, and vulnerabilities on a network or computer system. This can be done using various tools and techniques, such as ping sweeps, port scans, and vulnerability scans. The purpose of scanning is to gather information about the network or system, identify potential security risks, and detect any unauthorized access or activity.
Scanning can be performed both legally and illegally, depending on the purpose and context, and it is a key step in the reconnaissance phase of a cyber attack. Security professionals use scanning as a way to identify vulnerabilities that need to be addressed, and attackers use scanning to identify potential targets for attacks.
Answer: handwrite,scan the activity, and submit
I'm not sure why there's runtime errors in my code
Object temp = thePile.elementAt(i);
thePile.setElementAt(thePile.elementAt(j), i);
thePile.setElementAt(temp, j);
public Solitaire() {
window = new SolitaireFrame();
initialize();
window.show();
}
public void addCard(Card aCard) {
thePile.push(aCard);
}
private Stack thePile;
public class Main {
public static void main(String[] args) {
new Solitaire();
}
}
Answer: Object temp = thePile.element At(i); th Pile.setElementAt(thePile.elementAt(j), i); thePile.setElementAt(temp, j); public Solitaire() { window = new SolitaireFrame(); initialize(); window.show(); } public void addCard(Card aCard) { thePile.push(aCard); } private Stack thePile; public class Main { public static void main(String[] args) { new Solitaire(); } }
Explanation:
Based on the code given , it appears that there are no syntax errors. However, there are a few issues that might cause runtime errors:
The class "SolitaireFrame" might not be defined or imported properly.The class "Card" might not be defined or imported properly.The method "initialize()" might not be defined or implemented correctly.The class "Stack" might not be defined or imported properly.The variable "thePile" might not be initialized before use.The elements at i and j in the swap method might not be within the bounds of the stack.What is the runtime errors?The code creates an instance of a class called "Solitaire" and calls its constructor, which in turn initializes the window and calls the "initialize()" method. It then calls the "addCard()" method to add a card to a stack called "thePile".
Therefore, It also contains a swap method which is used to swap elements in a stack. The error message "runtime errors in the code" is not specific enough to determine the cause of the problem.

1/12
but why?
the first time you have a 1/4 chance, and the second time you have a 1/3 chance. since this is an AND event, we will multiply them together and get 1/12
