Program Description

Write a java program to calculate the area of triangle. The area of the triangle of base b, and height h is calculated using the mathematical formula:

Area of Triangle

Mathematical formula:

$Area of Triangle = \frac{ base * height}{ 2}$

Eclipse IDE Steps

We will use Eclipse IDE in this tutorial. Some steps and instructions to create a Java application:

Create Java Project in Eclipse

Java Program

The Java program prompts the user to enter the base and the height of the triangle. It computes the area of the triangle using the formula. The program displays the area to the console window.

import java.util.Scanner;

 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);
