Answer 1

Code:

import java.io.FileWriter;
import java.util.Scanner;
public class Rectangle {
   public static void main( String[] args )
   {
       float Length, Width, Area;
       float []lengtharray = new float[10];
       float []widtharray = new float[10];
       float []areaarray = new float[10];
       StringBuilder sb =new StringBuilder();
Scanner reader = new Scanner(System.in);
       for(int i=0;i<10;i++) {              
   System.out.print("Enter Length of Rectangle "+(i+1)+": ");
   Length = reader.nextFloat();
   lengtharray[i]=Length;
   System.out.print("Enter Width of Rectangle "+(i+1)+": ");
   Width = reader.nextFloat();  
   widtharray[i]=Width;
   Area = Length * Width;
   areaarray[i]=Area;     
       }
       System.out.println("\nRectangle\tLength\tWidth\tArea");
       sb.append("Rectangle\tLength\tWidth\tArea\n");
       float minArea=areaarray[0];
       float maxArea=areaarray[0];
       int minIndex=0,maxIndex=0;
       for(int i=0;i<10;i++) {
           if(minArea > areaarray[i]) {
               minArea = areaarray[i];
               minIndex=i;
           }
           if(maxArea < areaarray[i]) {
               maxArea = areaarray[i];
               maxIndex=i;
           }
          
           System.out.println(" "+(i+1)+"\t\t"+lengtharray[i]+"\t"+widtharray[i]+"\t"+areaarray[i]);
           //sb+=
           sb.append(" "+(i+1)+"\t\t"+lengtharray[i]+"\t"+widtharray[i]+"\t"+areaarray[i]+"\n");
       }      
       System.out.println("Largest Rectangle: "+(maxIndex+1)+". Area: "+maxArea);
       System.out.println("Smallest Rectangle: "+(minIndex+1)+". Area: "+minArea);
       sb.append("Largest Rectangle: "+(maxIndex+1)+". Area: "+maxArea+"\n");
       sb.append("Smallest Rectangle: "+(minIndex+1)+". Area: "+minArea+"\n");
      
       try{
   FileWriter fw=new FileWriter("D:\\testout.txt");
   fw.write(sb.toString());
   fw.close();
   }catch(Exception e){System.out.println(e);}
   }
}

Output:

Enter Length of Rectangle 1: 20 Enter Width of Rectangle 1 30 Enter Length of Rectangle 2: 10 Enter Width of Rectangle 2: 20 Enter Length of Rectangle 3: 15 Enter Width of Rectangle 3 10 Rectangle Length Width Area 20.0 10.0 15.0 30.0 20.0 10.0 600.0 200.0 150.0 2 Largest Rectangle: 1.
