Discuss what repetitions structures are, and how they differ from the vectorization approaches we have previously studied in the
gogolik [260]

Repetition structures, or loops, are used when a program needs to repeatedly process one or more instructions until some condition is met, at which time the loop ends. Many programming tasks are repetitive, having little variation from one item to the next. Vectorized mathematical code appears more like the mathematical expressions found in textbooks, making the code easier to understand. That is the difference. Hope I could help you on Brainly.com!

How do you fix this windows 7 screen​
tensa zangetsu [6.8K]

Try restarting it. If you can’t restart because the screen is frozen maybe just turn it off and back on. If you already tried restarting and it still didn’t fix the problem, just give it some time. The computer will reset itself eventually which should fix the problem.

This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balance
aksik [14]

Answer:

import java.util.Scanner;

public class TeamRoster {

  public static void main(String[] args) {

     Scanner scan = new Scanner(System.in);

     int[][] players = new int[5][2];

     boolean keepAlive = true;

     char input;

     

     for (int i = 0; i < 5; i++) {

        System.out.println("Enter player " + (i+1) + "'s jersey number: ");

        players[i][0] = scan.nextInt();

        if( players[i][0] >= 0 && players[i][0] < 100 ) {

             System.out.println("Enter player number less than 100");

               System.out.println("Enter player " + (i+1) + "'s rating: ");

               players[i][1] = scan.nextInt();

               if ( players[i][1] >= 1 && players[i][1] <10 ) {

                     System.out.println();

               }    else {

                     System.out.println("Enter player " + (i+1) + "'s rating: ");

                     players[i][1] = scan.nextInt();

               }

     }

     }

     System.out.println();

     outputRoster(players, 0);

     

     while (keepAlive) {

        outputMenu();

        input = scan.next().charAt(0);

        if (input == 'q') {

           keepAlive = false;

           break;

        } else if (input == 'o') {

           outputRoster(players, 0);

        } else if (input == 'u') {

           System.out.println("Enter a jersey number: ");

           int jerseyNum = scan.nextInt();

           System.out.println("Enter a new rating for the player: ");

           int newRating = scan.nextInt();

           for (int l = 0; l < 5; l++) {

              if (players[l][0] == jerseyNum) {

                 players[l][1] = newRating;

              }

           }

        } else if (input == 'a') {

           System.out.println("Enter a rating: ");

           int rating = scan.nextInt();

           outputRoster(players, rating);

        } else if (input == 'r') {

           System.out.println("Enter a jersey number: ");

           int jerseyNum = scan.nextInt();

           boolean exists = true;

           for (int l = 0; l < 5; l++) {

              if (players[l][0] == jerseyNum) {

                 System.out.println("Enter a new jersey number: ");

                 players[l][0] = scan.nextInt();

                 System.out.println("Enter a rating for the new player: ");

                 players[l][1] = scan.nextInt();

              }

           }

           

        }

     }

     

     return;

  }

   

  public static void outputRoster(int[][] players, int min) {

     System.out.println(((min>0) ? ("ABOVE " + min) : ("ROSTER")));

     int item = 1;

     for (int[] player : players) {

        if (player[1] > min) {

           System.out.println("Player " + item + " -- Jersey number: " + player[0] + ", Rating: " + player[1]);

        }

        item++;

     }

     System.out.println();

  }

   

  public static void outputMenu() {

     System.out.println("MENU");

     System.out.println("u - Update player rating");

     System.out.println("a - Output players above a rating");

     System.out.println("r - Replace player");

     System.out.println("o - Output roster");

     System.out.println("q - Quit\n");

     System.out.println("Choose an option: ");  

  }

}

Explanation:

The program is written in Java.

It is a bit straightforward.

The Scanner module is declared and used to collect input from the user.

The program prompts the user for each player jersey then rating.

All five players details are collected.

The program shows the output of all the entries.
