Return thread's runtime?

Question

Is there anyway to get the runtime of a thread when calling the start() method? My intention is to kick off a number of threads, have those threads run in parallel and finish, then output some sort of report about which thread completed in the shorted amount of time, the longest amount of time, etc....
I'm doing something along these lines ....
import java.util.Date;
import java.io.*;
public class LdapSearchThreaded extends Thread  {
        long threadTime;
        public LdapSearchThreaded(String str) {
                super(str);
        public void run() {
                long startTime = start.getTime();
                Date now = new Date();
                System.out.println("START: " + getName());
                //************* do a bunch of stuff
                Date stop = new Date();
                long stopTime = stop.getTime();
                threadTime = stopTime - startTime;
class ThreadedSearch {
        public static void main (String[] args) {
                for (int i = 0; i<5; i++){
                        LdapSearchThreaded search = new LdapSearchThreaded("Thread_" + i);
                        search.start();
                // output stats on all the treads......
}Thanks!

You could do:
public class LdapSearchThreaded extends Thread  {
    public long getThreadTime() {
        return threadTime;
    public boolean hasThreadEnded() {
        return threadTime != 0;
class ThreadedSearch {
    public static void main (String[] args) {
        ArrayList searchList = new ArrayList();
        for (int i = 0; i<5; i++) {
                LdapSearchThreaded search = new LdapSearchThreaded("Thread_" + i);
                search.start();
                searchList.add(search);
        // output stats on all the treads......
}
