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; /***************************************************************** * AreaOfTriangle.java * @program : Java program to calculate the area * @web : www.testingdocs.com * @version : 1.0 ******************************************************************/ public 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); } }
Run the Program
Run the Java application to verify the program.
