Explanation of Solution

Constraining a type parameter of a generic class with an upper bound:

“Yes”, type parameter of generic class can be constrained with an upper bound using the keyword extends.

Explanation:

The keyword extends is used to restrict the type parameter of generic class.

A type to an upper bound is constrained by the keyword extends.

In order to declare the type parameter with an upper bound, the developer list the name of type parameter, followed by the keyword extends, and followed by its upper bound.

Example:

public class exam<T extends Number> //Line1

{ //Line2

    private T to; //Line3

    private T ra; //Line4

    public exam(T tot, T rank) //Line5

    { //Line6

        to= tot; //Line7

        ra=rank; //Line8

    } //Line9

    public static void main (String[] args) //Line10

    { //Line11

        exam<Integer> e1= new exam<>(2,3); //Line12

        exam<Double> e2= new exam<>(466...

Explanation of Solution

Constraining a type parameter of a generic class with a lower bound:

“Yes”, type parameter of generic class can be constrained with lower bound using the keyword super.

Explanation:

The keyword super is used to restrict the type parameter.

A type to a lower bound is constrained by the keyword super.

In order to declare the type parameter with lower bound, the developer list the name of type parameter, followed by the keyword super, and followed by its lower bound.

Example:

public class exam<T super Integer> //Line1

{ //Line2

    private T to; //Line3

    private T ra; //Line4

    public exam(T tot, T rank) //Line5

The following is code for a disc golf program written in C++: // player.h #ifndef PLAYER_H #define PLAYER_H #include <string> #include <iostream> class Player { private: std::string courses[20]; // Array of course names int scores[20]; // Array of scores int gameCount; // Number of games played public: Player(); // Constructor void CheckGame(int playerId, const std::string& courseName, int gameScore); void ReportPlayer(int playerId) const; }; #endif // PLAYER_H // player.cpp #include "player.h" #include <iomanip> Player::Player() : gameCount(0) {} void Player::CheckGame(int playerId, const std::string& courseName, int gameScore) { for (int i = 0; i < gameCount; ++i) { if (courses[i] == courseName) { // If course has been played, then check for minimum score if (gameScore < scores[i]) { scores[i] = gameScore; // Update to new minimum…

In this assignment, you will implement a multi-threaded program (using C/C++) that will check for Prime Numbers and Palindrome Numbers in a range of numbers. Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…
