Class SALE

Hi Friend,

We have create a loop for only 3 items, you can modify it to 10.
import java.io.*;
import java.util.*;

public class SALE {
public static void main(String[] args) throws Exception {
ArrayList l1=new ArrayList();
ArrayList l2=new ArrayList();
ArrayList l3=new ArrayList();
ArrayList l4=new ArrayList();
ArrayList l5=new ArrayList();
ArrayList l6=new ArrayList();
ArrayList l7=new ArrayList();

Hope that the above code will be helpful for you.
Thanks
