I did not understand your count logic.
You will get count value : Number of matches (start count with 0).
count is giving correct value

check this code

Code:

import java.util.ArrayList;
public class CompareList
{

public static void main(String[] args){
	ArrayList list1 = new ArrayList();
	list1.add(10);
	list1.add(20);
	list1.add(30);
	list1.add(40);
	ArrayList list2 = new ArrayList();
	list2.add(11);
	list2.add(12);
	list2.add(13);
	list2.add(14);
	list2.add(15);
	list2.add(16);
	list2.add(17);
	list2.add(18);
	list2.add(19);
	list2.add(20);

	int s = 1;

	int count=0;

		for (int i=0;i<list2.size();i++) {
			if(s <= 4){
				System.out.println("Values..:"+list2.get(i));
				for (int j=0;j<list1.size(); j++) {
						if(list2.get(i).equals(list1.get(j))){
							count++;
							System.out.println("equals..:"+list1.get(j));
						}
				}
				s++;
			}else{
				System.out.println("Checked Four elements, Now checking next Four");
				s = 1;
				i--;
			}
		}

		System.out.println(count);
		if(count==list2.size()-4) {
		System.out.println("The level of the prize is FOUR "+count);
		}else if(count==list2.size()-3) {
		System.out.println("The level of the prize is THREE"+count);
		} else if(count==list2.size()-2) {
		System.out.println("The level of the prize is TWO "+count);
		} else if(count==list2.size()-1) {
		System.out.println("The level of the prize is ONE "+count);
		} else if(count==list2.size()-0) {
		System.out.println("The level of the prize is ZERO "+count);
		}
		else System.out.println("There is no prize level ");

	}
}

What exactly mean...of .... if(count==list2.size()-4)
