Java program Thank you

Define and test a method called printRectangleArea that takes two parameters that are the length and width of a rectangle (area=length*width). The method calculates and prints the area of the rectangle. For example the method call printRectangleArea(10.0, 3.0) prints Area: 30.0 Test this method by calling it from the main method. Include the code and 2 test cases. public class Exercise7 {public static void main(String[] arg) {Scanner keyboard = new Scanner(System.in); SYJSteJIUeut.BlUn tin ("Please type the length: "); double length = keyboard.nextDouble(); System.out.println ("Please type the width: ") ? double width = keyboard.nextDouble(); printRectangleArea(length, width);}//Define method here.}

Explanation / Answer

Exercise7.java

import java.util.Scanner;

public class Exercise7 {

  
   public static void main(String[] args) {
       Scanner keyboard = new Scanner(System.in);
       System.out.print("Please type the length: ");
       double length = keyboard.nextDouble();
       System.out.print("Please type the width: ");
       double width = keyboard.nextDouble();
       printRectangleArea(length, width);

   }
   public static void printRectangleArea(double length, double width){
       double area = length * width;
       System.out.println("Area: "+area);
   }

}

Output:

Please type the length: 10
Please type the width: 3
Area: 30.0
