reate a simple text-based console game that implements at least three (3) interfaces

Create method:

Method name: maxIndex

Method parameters: An integer array named arr

Method return: An integer value

Method description: This method will find the index of the array arr with the maximum value.

For example, if arr ={1.0, 2.0, 5.5, 1.5}, then it returns 2 since the maximum is 5.5 and it is present in index 2. In case, there are two same values, it returns the index of the last same value.

Can u pls explain to me the details of this program? how did it come up to this, the uses of each part

import java.util.Scanner;

public class Activity3 {

public static void main(String[] args) {

System.out.println(two(5,3));

  }

  public static int one(int x, int y) {

    return x > y ? x + y : x - y * 2;

  }

  public static double two(int x, double a) {

    Scanner in = new Scanner(System.in);

    int first = one(6, 8);

    double z = in.nextDouble();

    z += a;

    first += x;

    return z > first * 2 ? z : 2 * first - z;

  }

We want to calculate the total marks of each student of a class in Physics, Chemistry and Mathematics and the average marks of the class. The number of students in the class are entered by the user. Create a class named Marks with data members for roll number, name and marks. Create three other classes inheriting the Marks class, namely Physics, Chemistry and Mathematics, which are used to define marks in individual subject of each student. Roll number of each student will be generated automatically.

You are a system administrator with broad access to enterprise systems. Your supervisor has asked you to begin archiving all of the emails and web activity logs of one of your co-workers.Typically requests of this nature are initiated through a formal communication from your campus’s legal office. You feel that this request is inappropriate and possibly at odds with standard campus procedure and processes.You raise your concerns with your supervisor, but are told that this is a sensitive matter, and details cannot be shared with you. After thinking more about the conversation, you had with your supervisor, you are under the impression that you might lose your job if you persist in discussing the matter further or if you refuse to carry out the task. What would you do? In your answer, refer to ethical codes and what IT

professionals need to commit to and mention a few general or common principles included in ethical codes.
