Write a program with a main method that asks the user to enter an array of 10 integers. Your main method then calls each of the
Kay [80]

Answer:

The remaining part of the question is given as follows:

printReverse - a void method that reverses the elements of the array and prints out all the elements in one line separated by commas (see sample output below).

getLargest - an int method that returns the largest value in the array.

computeTwice- a method that returns an array of int which contains 2 times of all the numbers in the array (see the sample output below).

Explanation:

// Scanner class is imported to allow the program receive

// user input

import java.util.Scanner;

// Arrays class is imported to allow the program display the array

// in a pretty way

import java.util.Arrays;

//The class definition

public class Solution {

   // main method is defined which signify beginning of program

  // execution

   public static void main(String[ ] args) {

       // an array is initialized with a size of 10

       int[] array =new int[10];

       // Scanner object scan is defined

       Scanner scan =new Scanner(System.in);

       // A loop is initiated to receive 10 user input to fill the array

       for(int i=0; i < 10; i++){

           System.out.print("Please enter number: ");

           array[i]=scan.nextInt();

       }

       

       // A blank line is print

       System.out.println();

       // printReverse method is called with the received array as

      // argument

       printReverse(array);

       // A blank line is print

       System.out.println();

       // The largest number is printed

       System.out.println("The largest number is: " + getLargest(array));

       // computeTwice method is called to display the array after

      // multiplying each element by 2

       computeTwice(array);

       System.out.println( "The values of the computed twice array is: " );

       // Arrays class is used to print the array in form of a string

      // not object

       System.out.println(Arrays.toString(array));

   }

   

   //printReverse method declared with inputArray as parameter.

   // It has no return type

   public static void printReverse(int[] inputArray){

       System.out.print("Here is the arrray in reverse order: ");

       // A loop goes through the array starting from the end

       // and display each element

       for(int i = (inputArray.length - 1); i >= 0; i--){

           if(i == 0){

               // If the last element, do not append comma

               System.out.print(inputArray[i]);

           } else {

               // If not the last element, do append a comma

               System.out.print(inputArray[i] + ", ");

           }

       }

   }

   

   // getLargest method is declared with inputArray as parameter

   //  it compare each element in the array and return the largest

   public static int getLargest(int[] inputArray){

       // The first element is assumed to be the largest before the

      // loop begin

       int max = inputArray[0];

       for(int i = 1; i < inputArray.length; i++){

           if (inputArray[i] > max){

               max = inputArray[i];

           }

       }

       return max;

   }

   

   // computeTwice is declared with inputArray as parameter

   // it loop through the array and multiply each element by 2

   // it then return a modified array

   public static int[] computeTwice(int[] inputArray){

       for(int i = 0; i < inputArray.length; i++){

           inputArray[i] *= 2;

       }

       return inputArray;

   }

}

Exercise 8.1.9: Diving Contest Your school is hosting a diving contest, and they need a programmer to work on the scoreboard! Yo
vampirchik [111]

Answer:

def calculate_score(theTuple):

    first, second, third = theTuple

    if first >= 0 and first <=10 and second >= 0 and second <=10 and third >= 0 and third <=10:

         print(first + second+third)

    else:

         print("Range must be 0 to 10")

Explanation:

This line defines the function

def calculate_score(theTuple):

This line gets the content of the function

    first, second, third = theTuple

The following if condition checks if the digits are in the range 0 to 10

    if first >= 0 and first <=10 and second >= 0 and second <=10 and third >= 0 and third <=10:

This calculates the sum

         print(first + second+third)

else:

If number is outside range 0 and 10, this line is executed

         print("Range must be 0 to 10")

If myClass has a constructor with a parameter of type String, select the other constructor that should be included.
JulijaS [17]

Answer:

d. public myClass( ) {. . .}

Explanation:

A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.

Having said these about a constructor, a few other things are worth to be noted by a constructor.

i. In Java, a constructor has the same name as the name of its class.

For example, in the given class <em>myClass</em>, the constructor(s) should also have the name <em>myClass</em>.

ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:

<em>public void myClass(){...}</em>

This makes option a incorrect.

iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts  of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.

This makes option d a correct option.

Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.
