Program Plan Intro
Random Cipher
Program plan:
- Import the required java packages.
- Create the class StringRandom.
- Declare the required variables.
- Declare the constructor.
- Define the method generteString() to generate the output string for the user entered input string.
- Define the method generate() to generate the output string.
- Define the method ecoding() to encrypt the user entered string.
- Define the method print() to print the output on the console window.
- Define the main() method,
- Create the object for StringRandom class.
- Get the input from the user using the scanner class
- Pass the values for parameters using the object and call the constructor to perform the defined function.

How can predictive and prescriptive modeling be used to measure operational performance in real-time? Do you see any potential downsides to this application? Can you provide an example?
Tracing the Recursion.
Tracing the Recursion. Observe the recursive solution provided below.
1. Which line(s) of this program define(s) the base case of sumOfDigits() method?
2. Which line(s) of this program include recursive call(s)?
3. Trace the recursion below. You must show the trace step by step; otherwise – little
to no credit!
4. Show me the final result!

Question3: (30 MARKS) Passenger Rail Agency for South Africa Train Scheduling System Problem Statement Design and implement a train scheduling system for Prasa railway network. The system should handle the following functionalities: 1. Scheduling trains: Allow the addition of train schedules, ensuring that no two trains use the same platform at the same time at any station. 2. Dynamic updates: Enable adding new train schedules and canceling existing ones. 3. Real-time simulation: Use multithreading to simulate the operation of trains (e.g., arriving, departing). 4. Data management: Use ArrayList to manage train schedules and platform assignments. Requirements 1. Add Train Schedule, Cancel Scheduled Train, View Train Schedules and Platform Management 2. Concurrency Handling with Multithreading i.e Use threads to simulate train operations,…

Define an array of numbers, then on the array use the appropriate array iterator to determine if the array contains only even numbers using the function you defined.
