Java program to find area of triangle

Let’s learn java program to find area of triangle.

Java program to find area of triangle

In the below java program user enters base-width and height of triangle using nextDouble() method of Scanner class.

Also read – inheritance in java

To calculate area of triangle formula is:

Area = (width * height) / 2

Here’s the java program.

import java.util.Scanner;
public class FindAreaOfTriangle
{
   public static void main(String[] args)
   {
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter width of triangle: ");
      double base = sc.nextDouble();
      System.out.println("Please enter height of triangle: ");
      double height = sc.nextDouble();
      // formula area of triangle = (width * height) / 2
      double area = (base * height) / 2;
      System.out.println("Area of triangle is: " + area);
      sc.close();
   }
}


Output:

Please enter width of triangle: 5
Please enter height of triangle: 5
Area of triangle is: 12.5
