Write a Java program to find the mirror image of a point(2-D) which is taken from the user with respect to the origin.

I am working on writing a Java program that computes the total surface area of a rectangular prism like the one below. Here is what I have.  But Its asking for me to write the output using printf but here I have a println statment.    package idk; import java.util.Scanner; public class MainClass  { public static void main(String[] args)  { Scanner input = new Scanner(System.in); System.out.print("Enter the length (in inches):  "); double length = input.nextDouble(); System.out.print("Enter the width (in inches):  "); double width = input.nextDouble(); System.out.print("Enter the height (in inches):  "); double height = input.nextDouble(); } public static double calcArea(double length, double width, double height) { double totalArea =  2*(length + width + height); returntotalArea;   System.out.print("The total area for a rectangular prism "  +length+ "inches long "  +width+  "inches wide, and " +height+ "inches tall is"  +area+ "square inches." );   How do I switch the print to printf?
