12.10 Lab8Num3 (IN JAVA)

Repeat Lab8Num2, but this time with Circles Input file is called lab8.in

This is lab8num2 right here

Input is from a file. The input is all doubles. You are to input these doubles 2 at a time (the length and width), create a Rectangle and determine if it has the largest area. Output the Rectangle with the largest area.

import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner;
