17. Phone Book ArrayList Write a class named PhoneBookEntry that has fields for a person's name and phone number. The class should have a constructor and appropriate accessor and mutator methods. Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.

Make a declaration that sets the object's monthlyPay reference variable.array that can hold decimal numbers

Bubble Sorting an Array of ObjectsCreate a Student class and you will need to do the following: Enter the number of students (must be greater than 5). Enter the student’s names and grades Make sure that you enter the names and grades in random order. Iterate through the array of students and using the bubble sort, order the array by grade.

What happens when an object such as an array is no longer referenced by a variable?

In visual basic Write the code that will sequentially search through the array strFirstNames and will print out the word "Found" if the name "Brian" is in the array.

When an array is passed as a parameter to a method, modifying the elements of the array from inside the function will result in a change to those array elements as seen after the method call is complete. O True O False

C PROGRAMMING HELP I need help fixing an old assignment of mine. The point of the script is to read the pasted/attached Number_new.txt file's contents, meant to represent a classes' final grades out of 100 percent, and print an .exe screen as well as another .txt file that repeats the grade number with a letter grade and a PASS or FAIL next to it. At the end it needs to say how many students passed and how many failed. Nothing too complicated with the grading, just 90.0 and up is an A, 80.0 to 89.99 is a B, etc. And of course, anything below 60.0 is an F/FAIL. Please NO IOSTREAM.H OR CACIO.H! I cant use those header files. Below is the script: #include<stdio.h>#include<math.h>#define THEFILE "Number_new.txt" int main(){ float r0[10]; float rr[10]; FILE *fp; char line[81]; fp = fopen(THEFILE, "Number_new.txt"); if (fp != NULL) { /* The file is open. */ printf("%7s %7s %7s %7s %7s %7s %7s %7s %7s %7s\n", "0", "0.01",...

create an array of 3 Circle object references with radius = 1, 2 and 3 respectively. it should look like: Circle: radius = 1.00 area = 3.14 circumference = 6.28 then create one Circle reference called circle here. Assign 3 radii to the object: 10, 12 and 14 respectively. Print out should look like Circle: radius = 10.00 area = 314.16 circumference = 62.83

Java

When you pass an array as an argument, what is passed into the parameter variable?

1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the...

C++ CODE HELP NEEDED NEED MISSING CODE THAT WILL Read an integer as the number of Goat objects. Assign myGoats with an array of that many Goat objects. For each object, call object's Read() followed by the object's Print(). Ex: If the input is 2 5 87 7 71, then the output is: Goat's age: 5 Goat's weight: 87 Goat's age: 7 Goat's weight: 71 Goat with age 7 and weight 71 is deallocated. Goat with age 5 and weight 87 is deallocated. #include <iostream>using namespace std; class Goat { public: Goat(); void Read(); void Print(); ~Goat(); private: int age; int weight;};Goat::Goat() { age = 0; weight = 0;}void Goat::Read() { cin >> age; cin >> weight;}void Goat::Print() { cout << "Goat's age: " << age << endl; cout << "Goat's weight: " << weight << endl;}Goat::~Goat() { // Covered in section on Destructors. cout << "Goat with age " << age << " and weight " <<...
