5.27 LAB*: Program: Soccer team roster (Vectors)
This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balanced team.
(1) Prompt the user to input five pairs of numbers: A player's jersey number (0 - 99) and the player's rating (1 - 9). Store the jersey numbers in one int vector and the ratings in another int vector. Output these vectors (i.e., output the roster). (3 pts)
Ex:
Enter player 1's jersey number:
84
Enter player 1's rating:
7
Enter player 2's jersey number:
23
Enter player 2's rating:
4
Enter player 3's jersey number:
4
Enter player 3's rating:
5
Enter player 4's jersey number:
30
Enter player 4's rating:
2
Enter player 5's jersey number:
66
Enter player 5's rating:
9
ROSTER
Player 1 -- Jersey number: 84, Rating: 7
Player 2 -- Jersey number: 23, Rating: 4
...
(2) Implement a menu of options for a user to modify the roster. Each option is represented by a single character. The program initially outputs the menu, and outputs the menu after a user chooses an option. The program ends when the user chooses the option to Quit. For this step, the other options do nothing. (2 pts)
Ex:
MENU
a - Add player
d - Remove player
u - Update player rating
r - Output players above a rating
o - Output roster
q - Quit
Choose an option:
(3) Implement the "Output roster" menu option. (1 pt)
Ex:
ROSTER
Player 1 -- Jersey number: 84, Rating: 7
Player 2 -- Jersey number: 23, Rating: 4
...
(4) Implement the "Add player" menu option. Prompt the user for a new player's jersey number and rating. Append the values to the two vectors. (1 pt)
Ex:
Enter a new player's jersey number:
49
Enter the player's rating:
8
(5) Implement the "Delete player" menu option. Prompt the user for a player's jersey number. Remove the player from the roster (delete the jersey number and rating). (2 pts)
Ex:
Enter a jersey number:
4
(6) Implement the "Update player rating" menu option. Prompt the user for a player's jersey number. Prompt again for a new rating for the player, and then change that player's rating. (1 pt)
Ex:
Enter a jersey number:
23
Enter a new rating for player:
6
(7) Implement the "Output players above a rating" menu option. Prompt the user for a rating. Print the jersey number and rating for all players with ratings above the entered value. (2 pts)
Ex:
Enter a rating:
5
Answers
Answer:
Explanation:
The following code is written in Java and loops five times asking for the desired inputs from the user and saves that information in two Vectors named jerseyNumber and ratings. Then creates a while loop for the menu and a seperate method for each of the options...
import java.util.Scanner;
import java.util.Vector;
class Brainly {
static Scanner in = new Scanner(System.in);
static Vector<Integer> jerseyNumber = new Vector<>();
static Vector<Integer> ratings = new Vector<>();
public static void main(String[] args) {
for (int x = 0; x < 5; x++) {
System.out.println("Enter player " + (x+1) + "'s jersey number:");
jerseyNumber.add(in.nextInt());
System.out.println("Enter player " + (x+1) + "'s rating:");
ratings.add(in.nextInt());
}
boolean reloop = true;
while (reloop == true) {
System.out.println("Menu");
System.out.println("a - Add player");
System.out.println("d - Remove player");
System.out.println("u - Update player rating");
System.out.println("r - Output players above a rating");
System.out.println("o - Output roster");
System.out.println("q - Quit");
char answer = in.next().charAt(0);
switch (answer) {
case 'a': addPlayer();
break;
case 'd': removePlayer();
break;
case 'u': updatePlayer();
break;
case 'r': outputRating();
break;
case 'o': outputRoster();
break;
case 'q': System.exit(0);
reloop = false;
break;
}
}
}
public static void addPlayer() {
System.out.println("Enter player's jersey number:");
jerseyNumber.add(in.nextInt());
System.out.println("Enter player's rating:");
ratings.add(in.nextInt());
}
public static void removePlayer() {
System.out.println("Enter Jersey number:");
int number = in.nextInt();
for (int x = 0; x < jerseyNumber.size(); x++) {
if (jerseyNumber.get(x) == number) {
jerseyNumber.remove(x);
ratings.remove(x);
}
}
}
public static void updatePlayer() {
System.out.println("Enter Jersey number:");
int number = in.nextInt();
System.out.println("Enter new Rating:");
int rating = in.nextInt();
for (int x = 0; x < jerseyNumber.size(); x++) {
if (jerseyNumber.get(x) == number) {
ratings.set(x, rating);
}
}
}
public static void outputRating() {
System.out.println("Enter Rating:");
int rating = in.nextInt();
for (int x = 0; x < ratings.size(); x++) {
if (ratings.get(x) >= rating) {
System.out.println(jerseyNumber.get(x));
}
}
}
public static void outputRoster() {
for (int x = 0; x < jerseyNumber.size(); x++) {
System.out.println("Player " + (x+1) + " -- Jersey number: " + jerseyNumber.get(x) + ", Rating: " + ratings.get(x));
}
}
}

outline four advantages of digital
cameras over analogue cameras
Answers
Answer:
Explanation:
A digital camera refers to a camera whereby the photographs are being captured in digital memory. An analogue camera refers to the traditional camera that typically sends video over cable.
The advantages of digital cameras over analogue cameras include:
1. Massive Storage Space:
There is a large storage space for photos and thus helps to prevent limitations to film. There are memory cards that can store several images.
2. Multiple functions:
The digital camera performs several functions like face detection, night and motion detection This makes capturing of images more fun and brings about better images.
3. Video Camera:
Digital cameras can also capture moving pictures while analog camera typically captures images that are still. Digital camera is vital as it can be used for live streaming.
4. Smaller and Lighter:
Digital cameras are usually smaller and lighter which makes them more portable and easy to carry about.

Answers
Answer:
The program is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String score;
System.out.print("Scores: ");
score = input.nextLine();
String[] scores_string = score.split(" ");
double total = 0;
for(int i = 0; i<scores_string.length;i++){
total+= Double.parseDouble(scores_string[i]); }
double average = total/scores_string.length;
System.out.format("Average: %.3f", average); }
}
Explanation:
This declares score as string
String score;
This prompts the user for scores
System.out.print("Scores: ");
This gets the input from the user
score = input.nextLine();
This splits the scores into an array
String[] scores_string = score.split(" ");
This initializes total to 0
double total = 0;
This iterates through the scores
for(int i = 0; i<scores_string.length;i++){
This calculates the sum by first converting each entry to double
total+= Double.parseDouble(scores_string[i]); }
The average is calculated here
double average = total/scores_string.length;
This prints the average
System.out.format("Average: %.3f", average); }
}

Write a recursive method called permut that accepts two integers n and r as parameters and returns the number of unique permutations of r items from a group of n items. For given values of n and r, this value P(n, r) can be computed as follows:
n!/(n - r)!
For example , permut (7, 4) should return 840.

Answer:
Following are the code to the given question:
public class Main//defining a class Main
{
static int permut(int n, int r)//defining a method permut that holds two variable
{
return fact(n)/fact(n-r);//use return keyword to return calcuate value
}
static int fact(int n)//defining a fact method as recursive to calculate factorials
{
return n==0?1:n*fact(n-1);//calling the method recursively
}
public static void main(String[] abs)//main function
{
//int n=7,r=4;//defining integer variable
System.out.println(permut(7,4));//use print method to call permut method and print its values

In java I need help on this specific code for this lab.
Problem 1:
Create a Class named Array2D with two instance methods:
public double[] rowAvg(int[][] array)
This method will receive a 2D array of integers, and will return a 1D array of doubles containing the average per row of the 2D array argument.
The method will adjust automatically to different sizes of rectangular 2D arrays.
Example: Using the following array for testing:
int [][] testArray =
{
{ 1, 2, 3, 4, 6},
{ 6, 7, 8, 9, 11},
{11, 12, 13, 14, 16}
};
must yield the following results:
Averages per row 1 : 3.20
Averages per row 2 : 8.20
Averages per row 3 : 13.20
While using this other array:
double[][] testArray =
{
{1, 2},
{4, 5},
{7, 8},
{3, 4}
};
must yield the following results:
Averages per row 1 : 1.50
Averages per row 2 : 4.50
Averages per row 3 : 7.50
Averages per row 4 : 3.50
public double[] colAvg(int[][] array)
This method will receive a 2D array of integers, and will return a 1D array of doubles containing the average per column of the 2D array argument.
The method will adjust automatically to different sizes of rectangular 2D arrays.
Example: Using the following array for testing:
int [][] testArray =
{
{ 1, 2, 3, 4, 6},
{ 6, 7, 8, 9, 11},
{11, 12, 13, 14, 16}
};
must yield the following results:
Averages per column 1: 6.00
Averages per column 2: 7.00
Averages per column 3: 8.00
Averages per column 4: 9.00
Averages per column 5: 11.00
While using this other array:
double[][] testArray =
{
{1, 2},
{4, 5},
{7, 8},
{3, 4}
};
must yield the following results:
Averages per column 1: 3.75
Averages per column 2: 4.75
My code is:
public class ArrayDemo2dd
{
public static void main(String[] args)
{
int [][] testArray1 =
{
{1, 2, 3, 4, 6},
{6, 7, 8, 9, 11},
{11, 12, 13, 14, 16}
};
int[][] testArray2 =
{
{1, 2 },
{4, 5},
{7, 8},
{3,4}
};
// The outer loop drives through the array row by row
// testArray1.length has the number of rows or the array
for (int row =0; row < testArray1.length; row++)
{
double sum =0;
// The inner loop uses the same row, then traverses all the columns of that row.
// testArray1[row].length has the number of columns of each row.
for(int col =0 ; col < testArray1[row].length; col++)
{
// An accumulator adds all the elements of each row
sum = sum + testArray1[row][col];
}
//The average per row is calculated dividing the total by the number of columns
System.out.println(sum/testArray1[row].length);
}
} // end of main()
}// end of class
However, it says there's an error... I'm not sure how to exactly do this type of code... So from my understanding do we convert it?
Answers
Answer:
Explanation:
The following code is written in Java and creates the two methods as requested each returning the desired double[] array with the averages. Both have been tested as seen in the example below and output the correct output as per the example in the question. they simply need to be added to whatever code you want.
public static double[] rowAvg(int[][] array) {
double result[] = new double[array.length];
for (int x = 0; x < array.length; x++) {
double average = 0;
for (int y = 0; y < array[x].length; y++) {
average += array[x][y];
}
average = average / array[x].length;
result[x] = average;
}
return result;
}
public static double[] colAvg(int[][] array) {
double result[] = new double[array[0].length];
for (int x = 0; x < array[x].length; x++) {
double average = 0;
for (int y = 0; y < array.length; y++) {
average += array[y][x];
}
average = average / array.length;
result[x] = average;
}
return result;
