1 Write a java program which calculates the area of either a Triangle or a Rectangle. Use Scanner to take an input field to tell you if the area to be calculated is for a Triangle or is for a Rectangle. Depending on that input - the program must call either the Triangle method or the Rectangle method. Each of those methods must receive 2 input fields from the user - one for base and one for height in order to calculate the area and then to print that area and the height and base from inside the method.

A Java program which calculates the area of either a Triangle or a Rectangle. Use Scanner to take an input field to tell you if the area to be calculated is for a Triangle or is for a Rectangle.

Explanation:

Use Scanner to take an input field to tell you if the area to be calculated is for a Triangle or is for a Rectangle.

Depending on that input - the program must call either the Triangle method or the Rectangle method.

import java.util.Scanner;

class AreaOfRectangle {

  public static void main (String[] args)

  {

   Scanner scanner = new Scanner(System.in);

   System.out.println("Enter the length of Rectangle:");

   double length = scanner.nextDouble();

   System.out.println("Enter the width of Rectangle:");

   double width = scanner.nextDouble();

   //Area = length*width;

   double area = length*width;

   System.out.println("Area of Rectangle is:"+area);

  }

}

class AreaOfTriangle  

{

  public static void main(String args[])  

   {    

     Scanner s= new Scanner(System.in);

        System.out.println("Enter the width of the Triangle:");

        double b= s.nextDouble();

        System.out.println("Enter the height of the Triangle:");

         double h= s.nextDouble();

                 //Area = (width*height)/2

     double area=(b*h)/2;

     System.out.println("Area of Triangle is: " + area);      

  }

}

i believe the answer is spam
