Filename: “PairUtil.java”

This code snippet creates a class “PairUtil”. In the code,

  • Define a class “PairUtil”.
    • Define the method “minmax()”.
      • If the length of “a” equal to “0”,
        • Return “null”.
      • Declare a variable “min” of type “E” and set “a[0]” to it.
      • Declare a variable “max” of type “E” and set “a[0]” to it.
      • Iterate a “for” loop,
        • If the value of “element” is less than “min”,
          • Set “min” equal to “element”.

      • Set the value of “newBalance”.
      • Set the value of “balance”.
    • Define the method “getBalance()”.
      • Return the value of “balance”.
    • Define the method “compareTo()”.
      • Set the value of “d”.
      • If the value of “d” is less than 0,
        • Return “-1”.
          • If the value of “d” is greater than 0,
            • Return “1”.
          • Return “0”.

    • Define the method “SavingsAccount()”.
      • Set the value of “interestRate”.
    • Define the method “addInterest()”.
      • Set the value of “interest”.
      • Call the method “deposit()”.

Filename: “MinMaxTester.java”

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! 1 public class SumOfDigitsCalculator { 30 123456 7% 8 public static void main(String[] args) { System.out.println(sumOfDigits(1234)); } public static int sumOfDigits (int number) { if (number == 0) 9 10 11 12 } 13 } else return 0; return number % 10 + sumOfDigits (number / 10);

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,…
