Program 7 - Circle You write ALL the code, then run it - Produce the correct output. Turn in code and screen print of successful
fgiga [73]

Answer:

Here is the Circle class:

public class Circle {   // class definition

private int radius;    // private data member of type int of class Circle named radius that stores the value of radius

public Circle(int r) {   // parameterized constructor of class Circle that takes radius as argument

 radius = r;  }    // sets value of radius as r

public int getRadius() {   // accessor method to get the value of radius

 return radius;  }   // returns the current value of radius

public int Diameter() {   // method to compute diameter of a circle

 return radius * 2;  }   // multiply radius value by 2 to compute diameter of Circle

 

public double Area() {   // method to compute area of a circle

 return Math.PI  * Math.pow(radius, 2);   }   //the formula of area is

π x radius² where value of π is get using Math.PI

 

 public double Circumference() {   // // method to compute circumference of a circle

 return 2* Math.PI * radius;   }   }  //the formula of circumference is

2 x π x radius where value of π is get using Math.PI

Explanation:

Here is the Main class:

import java.util.Scanner;  //to accept input from user

public class Main {  //definition of Main class

public static void main(String[] args) {  //start of main method

   

    Scanner scanner = new Scanner (System.in);  //creates Scanner object to take input from user

    System.out.println("Enter radius: ");  //prompts user to enter radius

    int r = scanner.nextInt();  //reads the value of radius from user

 Circle c = new Circle(r);  // calls Constructor of Circle passing r as argument to it using the object c of class Circle

 

    if(c.getRadius()<=0){  //calls getRadius method to get current value of radius using objec and checks if this value (input value of r ) is less than or equal to 0

        System.out.println("Error!");   }  //when above if condition evaluates to true then print this Error! message

    else {  //if the value of radius is greater than 0

System.out.println("the radius of this Circle is: " +c.getRadius());  //calls getRadius method to return current value of r (input value by user)

System.out.println("the diameter of this Circle  is: " + c.Diameter());  //calls Diameter method to compute the diameter of Circle and display the result on output screen

System.out.printf("the circumference of this Circle  is: %.2f", c.Circumference());  //calls Circumference method to compute the Circumference of Circle and display the result on output screen

System.out.println();  //prints a line

System.out.printf("the Area of this Circle  is: %.2f", c.Area()); } }  }

//calls Area method to compute the Area of Circle and display the result on output screen

The program and its output is attached.

import java.util.ArrayList; // Needed for ArrayList class /** This program demonstrates how to store BankAccount objects in an A
slega [8]

Answer:

import java.util.ArrayList; // Needed for ArrayList class

/** This program demonstrates how to store BankAccount objects in an ArrayList. */

// Class ArrayListDemo6 is defined

public class ArrayListDemo6 {

// main method that begin program execution

public static void main(String[] args) {

// Create an ArrayList to hold BankAccount objects.

// The arraylist is called list

ArrayList list = new ArrayList();

// Add three BankAccount objects to the ArrayList.

list.add(new bankAccount(100.0)); list.add(new bankAccount(500.0)); list.add(new bankAccount(1500.0)); // Display each item using a for loop

for (int index = 0; index < array.size(); index++)

{ BankAccount account = list.get(index);

System.out.println("Account at index " + index + "\nBalance: " + account.getBalance());

}

}

}

Explanation:

The code is written in Java and more comments has been added to make it more explanatory.

The code snippet is a demonstration on Arraylist.

First Arraylist is imported. Then, ArrayListDemo6 class is defined. Then the main method which begin program execution.

Inside the main method, a new Arraylist is created called list.

Then we add three BankAccount object to the list.

Lastly, we use a for loop to display each added BankAccount object.
