Make a file called Rectangle.java. In this file, create the following methods:

//Ask the user for the length of the rectangle.

public static double getLength(Scanner keyboard)

//Ask the user for the width of the rectangle

public static double getWidth(Scanner keyboard)

//Calculate the area of the rectangle

public static double getArea(double length, double width)

//Display the information about the rectangle

public static void displayData(double length, double width)

Demo 5:

import org.w3c.dom.css.Rect; import java.util.Scanner; public class Demo5 { public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); double length = Rectangle.getLength(keyboard); double width = Rectangle.getWidth(keyboard); double area = Rectangle.getArea(length, width); System.out.printf("You entered: %.1f, %.1f, and %.1f ", length, width, area); Rectangle.displayData(length, width); } } 

method:

 import java.util.Scanner; import java.math.BigDecimal; public class Rectangle { public static double getLength(Scanner keyboard) { System.out.println("Enter length: "); return keyboard.nextDouble(); } public static double getWidth(Scanner keyboard) { System.out.println("Enter width: "); return keyboard.nextDouble(); } public static double getArea(double length, double width) { return length*width; } public static void displayData(double length, double width) { double area =length*width; System.out.println("-- Rectangle info --"); System.out.println("Length: "+length); System.out.println("Width: "+width); System.out.println("Area: "+area); } }

This is coding in Java and the problem I am having is that my numbers are going to the second decimals and im trying to make them round to the first.
