2 Ways To Find Area of Rectangle in Java Programming
Here, we have described Two Methods To Calculate Area of Rectangle in Java Programming Language. This is a Java Code To Find Area of Rectangle using Parameters with a self-explanatory program.
Area of Rectangle = Length * Breadth
Method 1: Java Program To Calculate Area of Rectangle 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 Rectangle { double length, breadth; double area() { return length * breadth; } } class Area { public static void main(String args[]) { double area; Rectangle rec1 = new Rectangle(); rec1.length = 20; rec1.breadth = 30; area = rec1.area(); System.out.println("\nArea of Rectangle: " + area + "\n"); } } |
