Chapter 12.3, Problem 20STQ
Explanation of Solution
Method definition for “isEmpty” for “StringLinkedList” class:
/* Method defintion for "isEmpty" method */
public boolean isEmpty()
{
/* Returns "true" if the list is empty. Otherwise returns "false" */
return head == null;
}
Explanation:
The above method definition is used to returns “true” if the value of “head” is equal to “null”. Otherwise returns “false”.
Complete code:
The complete code for after implementing “isEmpty” method is given below:
Filename: “ListNode.java”
//Define "ListNode" class
public class ListNode
{
/* Refer the textbook of Listing 12.4 */
}
Filename: “StringLinkedList.java”

Objective: The objective of this assignment is to gain practice with pen testing a live web
application running on a remote server. The live web application is a known vulnerable web
application called DVWA (Damn Vulnerable Web Application) with security settings set to low.
The web app is running on an AWS EC2 (Elastic Compute Cloud) instance running Ubuntu 22.
Note: The point of this assignment is to step it up a notch, we learnt about different web
application vulnerabilities and applied that knowledge, now we are going to pen test and
enumerable the vulnerabilities of a web app + the underlying infrastructure it is running on.

The host computers use private IP address space: 192.168.2/24. Each host is trying to establish 2 TCP connections to a remote webserver through the NAT router. The IP address of the webserver is: 130.12.11.9. Now do the following: 1 a. Assign IP addresses to the interfaces of the hosts and the router. For the router, assign arbitrary addresses. List these addresses. b. Now create a NAT translation table as taught in the class for all TCP connections. Assign arbitrary port numbers as required.arrow_forward
