Answer:

The correct answer to the following question is option 4.

Explanation:

The private class does not mean that the package-private, it means that no other class can see its members.

It is used in creating the building blocks which is implementing the internal functionality that you don't want to visible to the other projects using the library.

We can use private constructor to ensure that more than one object cannot be created at the time.

write a java program that prompts the user to enter scores (each number an integer from 0 to 10) and prints the following output

Vladimir [108]

Answer:

Explanation:

The following is written in Java. It continues asking the user for inputs until they enter a -1. Then it saves all the values into an array and calculates the number of values entered, the highest, and lowest, and prints all the variables to the screen. The code was tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

int count = 0;

int highest, lowest;

ArrayList<Integer> myArr = new ArrayList<>();

while (true) {

System.out.println("Enter a number [0-10] or -1 to exit");

int num = in.nextInt();

if (num != -1) {

if ((num >= 0) && (num <= 10)) {

count+= 1;

myArr.add(num);

} else {

System.out.println("Wrong Value");

}

} else {

break;

}

if (myArr.size() > 3) {

highest = myArr.get(0);

lowest = myArr.get(0);

for (int x: myArr) {

if (x > highest) {

highest = x;

}

if (x < lowest) {

lowest = x;

}

System.out.println("Number of Elements: " + count);

System.out.println("Highest: " + highest);

System.out.println("Lowest : " + lowest);

} else {

System.out.println("Number of Elements: " + count);

System.out.println("No Highest or Lowest Elements");

}

c++ Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins wi

Margaret [11]

Answer:

The following are the program in the C++ Programming Language:

#include <iostream> //header file

#include <string> //header file

#include <vector> //header file

//name space

using namespace std;

//main function

int main() {

vector<string> word; //set variable

vector<int> c; //set variable

int s, counts = 0; //set variable

string strng; //set variable

cout<<"Enter the size of string: "; //print message

cin >> s; //get input

cout<<"Enter the string: "; //print message

for(int i = 0; i < s; ++i) { //set for loop

cin >> strng; //get input

word.push_back(strng);

}

for(int i = 0; i < s; ++i) { //set for loop

counts = 0;

for(int j = 0;j<word.size();j++){ //set for loop

if(word[j] == word[i]){ //set if statement

counts++; //increament in counts

}

c.push_back(counts);

}

for(int i = 0; i < s; ++i) {

cout << word[i] << " " << c[i] << endl;//print result

}

return 0;

}

<u>Output</u>:

Enter the size of string: 2

Enter the string: hello sir

hello 1

sir 1

Explanation:

Here, we define three header files <iostream>, <String>, <vector> and namespace "std" after that we define main() method inside it.

Then, we set two vector type variables first one is string variable "word" and the second one is integer variable "c".
Then we set two integer variable "s" and "counts" and variable "counts" assign to 0.
Then, we get input from the user in variable "s" for the length of the loop.
Then, we set for the loop inside it, we get input in the variable "strng" from the user.
Then, we set the for loop for count the string repetition if any word comes again in the string then the value of count will increase.
Finally, we set for a loop to print the result.
