A Program to Find the Area of a Rectangle
In this example, we are giving a program to find the area of a rectangle. The rule of finding the area of a rectangle is: A = width * height.
Program to find the area of a rectangle:
import java.util.Scanner; //Scanner class helps to get input from user
class triangle {
public static void main(String[] args) {
Scanner s = new Scanner(System.in); //Scanner class object declaration
System.out.println("Enter the width of rectangle: ");
float w = s.nextFloat(); // takes float input width from keyboard or user or run time
System.out.println("Enter the height of rectangle: ");
float h = s.nextFloat(); // takes float input height from keyboard or user or run time
float area = w * h;
System.out.println("Area of Rectangle: "+ area);
}
}
Output:
Enter the width of rectangle: 3 Enter the height of rectangle: 4 Area of Rectangle: 12.00
