Consider the BankAccount class below.
public class BankAccount
{
private final String ACCOUNT_NUMBER;
private double balance;
public BankAccount(String acctNumber, double beginningBalance)
{
ACCOUNT_NUMBER = acctNumber;
balance = beginningBalance;
}
public boolean withdraw(double withdrawAmount)
{
/* missing code */
}
}
The class contains the withdraw method, which is intended to update the instance variable balance under certain conditions and return a value indicating whether the withdrawal was successful. If subtracting withdrawAmount from balance would lead to a negative balance, balance is unchanged and the withdrawal is considered unsuccessful. Otherwise, balance is decreased by withdrawAmount and the withdrawal is considered successful.
Which of the following code segments can replace /* missing code */ to ensure that the withdraw method works as intended?
I.
if (withdrawAmount > balance)
{
return "Overdraft";
}
else
{
balance -= withdrawAmount;
return true;
}
II.
if (withdrawAmount > balance)
{
return false;
}
else
{
balance -= withdrawAmount;
return balance;

DNS servers manage which server a user will access when they enter a domain name into their web browser by converting requests for names into IP addresses.

Recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers are the four categories into which all DNS servers fall. Domain name system, or DNS, converts a domain name into an Internet Protocol (IP) address. In light of this, the DNS converts IP addresses into a hierarchy of domain names. Internet Protocol (IP) addresses are translated into domain names during a reverse DNS lookup. Without DNS servers, the internet would not function at all. It is their job to convert domain names into IP addresses. Computers then identify and connect to those web servers using those IP addresses, directing users to the appropriate websites.

Class in computer science is a template or blueprint that is used to create objects. It is the basis for object-oriented programming (OOP). A class encapsulates data and functions that can be used to create objects of the same type. The data and functions within the class are called members. The members of a class can be public, meaning they are accessible from other classes, or private, meaning they are only accessible within the class. Classes also have a constructor, which is a function that is used to create objects from the class. Classes can have inheritance, meaning a class can inherit data and functions from another class.

Explanation:

I've written a basic Circle class and a Main class for testing it.

You will have to initialize the x and y yourself, since I don't know how big your screen is. It's just center of screen x/y - radius of circle. There is 2 constructor, one for color(r,g,b) and another for color(Color).

Review and test the code for yourself.

Rate 5 star, if this helped :)

Answer:

import java.util.*;

import java.awt.Color;//Must import Color class in Circle class

public class Main {

   public static void main(String[] args) {

     System.out.println("Creating circle: ");

     Circle c1 = new Circle(9,8,7, 100, 100,0);//rgb value

     c1.printCircle();

     Circle c2 = new Circle(1,2,3, Color.red);//color value

     c2.printCircle();

 }

}

public class Circle{

 private int x, y, radius;

 private Color color;

 //Constructor

 //parameter: x, y, radius, color in RGB VALUE

 public Circle(int x, int y, int radius, int r, int g, int b){

   this.x=x;

   this.y=y;

   this.radius=radius;

   color = new Color(r,g,b);

 }

 //Overloaded Constructor for color in strong VALUE

 public Circle(int x, int y, int radius, Color color){

   this.x=x;

   this.y=y;

   this.radius=radius;

   this.color = color;

 }

 //Test function. can delete after testing

 //Prints the x,y,radius, and color of circle

 public void printCircle(){

   System.out.printf("Circle: x:%d y:%d radius:%d color:%s\n",x, y, radius, color.toString());

 }

The code will print out the elements of the array "numArray" after they have been doubled by the "doubleFirstFive" method. The "doubleFirstFive" method takes in an array as a parameter and uses a for loop to double the value of the first 5 elements of the array, using the "&& i < 5" condition in the for loop to ensure that only the first 5 elements are doubled.

A similar method called "tripleFirstFour" that triples the first 4 elements of the array can be written as follows:

----------------------------------------------------------------------------

   // Notice: && i < 4

   for (int i = 0; i < values.length && i < 4; i++){

       values[i] = values[i] * 3;

   }

}

------------------------------------------------------------------

To test the method, you can add the following code in the main method:

-------------------------------------------------------------

tripleFirstFour(numArray);

printArray(numArray);

-------------------------------------------------------------

This will call the "tripleFirstFour" method on the numArray and then print the new array out on the console.

i. To work out the steps for the example input [1, 2, 3, 4, 5, 6], I would start by initializing two pointers, one at the beginning of the list and one at the end.

I would then swap the first and last elements, then move the pointers inwards one step and repeat the process until the pointers meet in the middle. The output in this case would be [3, 2, 1, 4, 5, 6].

ii. The pattern that emerges is that the first and last elements are always swapped, then the pointers move inwards one step, then the next pair of first and last elements are swapped, and so on until the pointers meet in the middle.

iii. Special cases to consider include lists with an odd number of elements, in which case the middle element does not need to be moved, and lists with only one or two elements, in which case no swapping needs to be done.

iv. A solution in python could be as follows:

def rearrange_list(my_list):

   left_pointer = 0

   right_pointer = len(my_list) - 1

   while left_pointer < right_pointer:

       my_list[left_pointer], my_list[right_pointer] = my_list[right_pointer], my_list[left_pointer]

       left_pointer += 1

       right_pointer -= 1

   return my_list

test_list = [1, 2, 3, 4, 5, 6, 7, 8]

print("Original list:", test_list)

print("Rearranged list:", rearrange_list(test_list))

This function can be tested with different lists .

The compare function that sorts numeric values in ascending order is: function ascending(a, b) { return a - b; }.

The compare function is a function used to compare two values or expressions. It is used to determine whether the two values or expressions are equal, less than, or greater than one another. It is commonly used in programming languages to compare strings, numbers, and objects. It can also be used to compare logical values, such as true or false.

This function takes two parameters, a and b, and returns the difference between them (a - b). This subtraction results in a negative value if a is less than b, and a positive value if a is greater than b. Therefore, when sorting numeric values in ascending order, the parameter with the smallest numerical value will be placed first.
