Answer:(c) abstract class A { abstract void unfinished(); }

Java languageThe cost to ship a package is a flat fee of 75 cents plus 25 cents per pound.1. Declare a constant named CENTS_PER_
Sophie [7]

Answer:

// Here is code in Java.

// import package

import java.util.*;

// class definition

class Main

{

   // main method of the class

public static void main (String[] args) throws java.lang.Exception

{

    try{

   // variables

    final int CENTS_PER_POUND = 25;

    final int FLAT_FEE_CENTS = 75;

    // Scanner object to read input

   Scanner sr=new Scanner(System.in);

   System.out.print("Enter the shipping weight:");

   // read the input weight

   int shipWeightPounds=sr.nextInt();

   // calculate total cost

  int shipCostCents = (shipWeightPounds * CENTS_PER_POUND) + FLAT_FEE_CENTS;

  // print Weight

  System.out.println("shipping  Weight: " + shipWeightPounds);

  // print flat fee

     System.out.println("flat fee of shipping in cents : " + FLAT_FEE_CENTS);

     // print cents per round

     System.out.println("Cents/pound for shipping: " + CENTS_PER_POUND);

     // print cost of Shipping

    System.out.println("total cost of shipping in cents: " + shipCostCents);

   

   

   }catch(Exception ex){

       return;}

}

}

Explanation:

Declare and initialize two constant variables "CENTS_PER_POUND=25" & "FLAT_FEE_CENTS = 75". Read the input weight from user with the help of Scanner class object. Then  calculate the cost of shipping by multiply weight with cent per pound and add flat fee. Then print each of them.

Output:

Enter the shipping weight:12                                                                                                                                  

shipping  Weight : 12                                                                                                                                        

flat fee of shipping in cents: 75                                                                                                                              

Cents/pound for shipping: 25                                                                                                                                  

total cost of shipping in cents: 375

This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balance
aleksandr82 [10.1K]

Answer:

Question Options :

(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 array and the ratings in another int array. Output these array(i.e., output the roster).

(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 pt)

(3) Implement the “Output roster” menu option. (1 pt)

(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 arrays. (1 pt)

(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)

(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)

(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)
