<u>Answer:</u>

CIRCLE.JAVA

public class Circle {

  <em>private</em><em> </em>double radius;

  <em>public</em> Circle(double myRadius) {

    radius = myRadius;

    private void setRadius(int myRadius){

    radius = myRadius;

 }

 <em>public </em>double getDiameter() {

    return radius*2;

 }

 public double getRadius() {

   return radius;

 }

 <em>public </em> double getPerimeter() {

   return Math.PI*getDiameter();

 }

 <em>public</em> String toString() {

    return "Circle with a radius of " + radius;

 }

}

CIRCLE TESTER.JAVA

public class CircleTester {

 public static void main(String[] args) {

    Circle circ = new Circle(10);

    circ.radius = 5;

    System.out.println(circ);

    System.out.println("The diameter is " + circ.getDiameter());

    System.out.println("The perimeter is " + circ.getPerimeter())

 }

}

<u>Explanation:</u>

public class Circle {

  //This could be made private or public.

  //Making it private is better

  <em>private</em><em> </em>double radius;

  //This is a constructor. It should be made public

  //since it would most likely be used in another class

  //to create an object of this class.

  //Making it private means no other external class can create

  //an object of this class.

  //Since the tester class (CIRCLETESTER.java), as shown on line 3,

  // needs to create

  //an object of this class, this should be made public

  <em>public</em> Circle(double myRadius) {

    radius = myRadius;

    private void setRadius(int myRadius){

    radius = myRadius;

 }

 //This should be made public since it will be

// used in another class (CIRCLETESTER.java in this case)

 <em>public </em>double getDiameter() {

    return radius*2;

 }

 public double getRadius() {

   return radius;

 }

 //This should be made public since it will be

 //used in another class (CIRCLETESTER.java)

 <em>public </em> double getPerimeter() {

   return Math.PI*getDiameter();

 }

 //The toString() method is the string representation

 //of an object and is called when there is an attempt to

 //print the object. It should be made public since it will

 //be used in another class (CIRCLETESTER.java)

 <em>public</em> String toString() {

    return "Circle with a radius of " + radius;

 }

}

CIRCLE TESTER.JAVA

public class CircleTester {

 public static void main(String[] args) {

    Circle circ = new Circle(10);

    circ.radius = 5;

    System.out.println(circ);

    System.out.println("The diameter is " + circ.getDiameter());

    System.out.println("The perimeter is " + circ.getPerimeter())

 }

}

What bit position in an ascii code must be complemented to change the ascii letter represented from uppercase to lowercase and v
MariettaO [177]
Flip bit position 5 to accomplish this. This maps to hex value 0x20, where the least significant bit is assumed to be at position 0.

Example: ascii "A" = 0x41, "a" = 0x61.  0x41 xor 0x61 = 0x20.

You would implement a flip function by XOR'ing the character value with 0x20.

in your own ideas what are the disadvantages of participating in a videoconference write your answer inside the circle​
ipn [44]
Some disadvantages of taking part in a video-conference are:

1) Lack of communication from social cues (social cues are what we use to see if someone is in a good or bad mood)

2) There is a high chance of unstable network connection.

3) Technical and personal issues because not everyone is comfortable speaking on a video-conference platform.

4) It causes more stress due to the lack of organization when preparing meetings (because it’s so easy to just get on a device without preparing anything beforehand).

The operating systems, and utility programs that perform system
Phantasy [73]

Answer:

System softwares.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.

Basically, softwares are categorized into two (2) main categories and these are;

I. Utility software.

II. System software.

The operating systems, and utility programs that perform system maintenance and protection tasks such as error correction and backup are called system softwares.

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

On the other hand, a utility software can be defined as a software application or program designed to add more functionality to a computer system, as well as to improve its performance efficiently. Some examples of commonly used utility tools in computer are file and folder backup tools, file management, antivirus, hard disk diagnostics, registry cleaner, network performance monitor, screensavers etc.
