Comparing and Creating new list in Java

Java Example code for creating and comparing lists using Java.

import java.util.*;

public class TwoList{
static List<String> makeList(int n) {
List<String> list = new ArrayList<String>(n);
while (n--> 0){
list.add(makeString());
}
return list;
}
static final Random random = new Random();
static String makeString() {
char [] s = new char[8];
for (int i=0; i< s.length; i++) {
s[i] = (char) ('A' + random.nextInt(3));
}
return new String(s);
}
static List<String> list1 = makeList(1000);
static List<String> list2 = makeList(5000);

public static void main(String [] args){
long log = System.currentTimeMillis();
Set<String> secondarySet = new HashSet<String>(list2);
int count = 0;
for (String str : list1) {
if (secondarySet.contains(str)) {
count++;
}
}
System.out.println(System.currentTimeMillis()-log);
System.out.println(count);
}
}
