Question

Area Program – Build a Java Class to Calculate the area of a Figure(call it “Area.java”. The figure may be a circle, or a square or a rectangle. The user will enter the type of figure they want through a Scanner. If they enter a “C”, proceed to calculate the area of the Circle using values read in for radius. If they enter an “S”, then calculate the area of a Square using values read in for side. If they enter an “R”, then calculate using values read in for height and width. Use “Select/Case” statements for this lab. The formulas for each figure are: Circle : Area = 3.14 * radius * radius Square : Area = side * side Rectangle : Area = Height * Width

Answer 1

ANSWER: Here I am giving you the CODE and output if you have any problem then comment or like it please.

CODE:

import java.util.Scanner;

public class Area {

   public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter your choice C for Circle or S for square or R for rectangle: ");
String Ch = sc.next() ;

if(Ch.equals("C")) {
   System.out.println("Enter the radius of the circle: ");
   float radius = sc.nextFloat();
   float area = (float) (3.14 * radius * radius);
   System.out.println("Area of the Circle will be : "+area);
  
}else if(Ch.equals("R")) {
   System.out.println("Enter the length and height of the rectangle: ");
   int Height=sc.nextInt();
   int Width= sc.nextInt();
   int Area = Height * Width;
   System.out.println("Area of the rectangle: "+Area);
}else if(Ch.equals("S")) {
   System.out.println("Enter the side of the square: ");
   int side=sc.nextInt();
   int area= side*side;
   System.out.println("Area of the square: "+area);
}else {
   System.out.println("Wrong choice.");
}
  

   }

}

OUTPUT:
