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.
Using the knowledge of pseudocodes it will be possible to write a code that calculates the amount of hours worked and giving warnings about it.
<h3>Writing a pseudocode we have that:</h3><em>while </em>
<em>if number == 0</em>
<em>break</em>
<em>hours =0 </em>
<em>for i =1 to 5 </em>
<em>hours = hours + time_out[ i ] - time_in[ i ]</em>
<em> If hours >36 : </em>
<em>print ( "Name is " ,name)</em>
<em>print( "No of hours are ",hours)</em>
<em>print("Congratulaion! Your working hours are more than 36")</em>
<em>If hours <30 : #</em>
<em>print ( "Name is " ,name)</em>
<em>print( "No of hours are ",hours)</em>
<em>print("Warning !!!")</em>
<em>End loop</em>
