## 2 Ways To Calculate Area of Triangle in Java

Here, we have described Two Methods To Calculate Area of Triangle in Java Programming Language. Java Code To Find Area of Triangle using Parameters with a self-explanatory program.

#### Area of Triangle = 0.5 * Base * Height

#### Method 1: Calculate Area of Triangle in Java without Parameters

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | import java.io.*; class Triangle { double base, height; double area() { return (0.5 * base * height); } } class Area { public static void main(String args[]) { double area; Triangle rec1 = new Triangle(); rec1.base = 20; rec1.height = 30; area = rec1.area(); System.out.println("\nArea of Triangle: " + area + "\n"); } } |
