QUESTION: Why I can't run this coding? . import java.util.*; public class Children {     String name;    int friends;    public Children(String name)    {        this.name = name;       friends = 0;    }    public void getFriend(Children k){        friends++;     }       public int numFriends() {        return friends;     }       public String playsalong(){        return "joy";     }       public String toString(){        return "a child named "+name;}    } class Girl extends Children {     public Girl(String name){        super(name);       friends = 1;     }    public void getFriend(Children k){        if (k instanceof Girl)         friends += k.numFriends( );       else       friends++;    }    public String toString( ){            return "a girl named "+ name;}    } class Boy extends Children {     public Boy(String name){         super(name);     }        public String toString(){        return "a boy named " +name; }  }

public static int countIt (int n) {     int count = 0;     for (int i = n; i > 0; i /= 2)          for (int j = 0; j < 10; j++)               count += 1;     return count; }   Big-O notation: Explanation:

List the name and return type of this method: public String getCode(){ return code;}

1. Insert the missing part of the code below to output the string. public class MyClass { public static void main(String[] args) { ("Hello, I am a Computer Engineer");

JAVA CODE: check output

Please make the code do what the description says.

Fix all errors to make the code compile and complete. //MainValidatorA3 public class MainA3 { public static void main(String[] args) { System.out.println("Welcome to the Validation Tester application"); // Int Test System.out.println("Int Test"); ValidatorNumeric intValidator = new ValidatorNumeric("Enter an integer between -100 and 100: ", -100, 100); int num = intValidator.getIntWithinRange(); System.out.println("You entered: " + num + "\n"); // Double Test System.out.println("Double Test"); ValidatorNumeric doubleValidator = new ValidatorNumeric("Enter a double value: "); double dbl = doubleValidator.getDoubleWithinRange(); System.out.println("You entered: " + dbl + "\n"); // Required String Test System.out.println("Required String Test:"); ValidatorString stringValidator = new ValidatorString("Enter a required string: "); String requiredString =…

How do I fix the errors? Code: import java.util.Scanner;public class ReceiptMaker { public static final String SENTINEL = "checkout";public final int MAX_NUM_ITEMS;public final double TAX_RATE;private String[] itemNames;private double[] itemPrices;private int numItemsPurchased; public ReceiptMaker() {MAX_NUM_ITEMS = 10;TAX_RATE = 0.0875;itemNames = new String[MAX_NUM_ITEMS];itemPrices = new double[MAX_NUM_ITEMS];numItemsPurchased = 0;}public ReceiptMaker(int maxNumItems, double taxRate) {MAX_NUM_ITEMS = maxNumItems;TAX_RATE = taxRate;itemNames = new String[MAX_NUM_ITEMS];itemPrices = new double[MAX_NUM_ITEMS];numItemsPurchased = 0;} public void greetUser() {System.out.println("Welcome to the " + MAX_NUM_ITEMS + " items or less checkout line");}public void promptUserForProductEntry() {System.out.println("Enter item #" + (numItemsPurchased + 1) + "'s name and price separated by a space, or enter \"checkout\" to end transaction early");}public void addNextPurchaseItemFromUser(String…

class TenNums {private:    int *p; public:    TenNums() {        p = new int[10];         for (int i = 0; i < 10; i++) p[i] = i;     }    void display() { for (int i = 0; i < 10; i++) cout << p[i] << " "; }};int main() {    TenNums a;      a.display();      TenNums b = a;      b.display();      return 0;} Continuing from Question 4, let's say I added the following overloaded operator method to the class. Which statement will invoke this method? TenNums TenNums::operator+(const TenNums& b) {  TenNums o;  for (int i = 0; i < 10; i++) o.p[i] = p[i] + b.p [i];  return o;} Group of answer choices TenNums a; TenNums b = a; TenNums c = a + b; TenNums c = a.add(b);
