Here is the code of the program:

 

 

 

 

import java.util.*;

public class ThreadedAccess implements Runnable{
  static int ThreadCount = 0;
  public void run(){
  String s = "This is thread " + ThreadCount++;
  Vector<String> v = new Vector<String>();
  v.addElement(s);
  v.addElement(s);
  try{
  Thread.sleep(2000);
  }
  catch(Exception e){}
  v.addElement(s);
  System.out.println(v);
  }
  
  public static void main(String[] args){
  try{
  for(int i = 0; i < 5; i++){
  (new Thread(new ThreadedAccess())).start();
  try{
  Thread.sleep(200);
  }
  catch(Exception e){}
  }
  }
  catch(Exception e){
  e.printStackTrace();
  }
  }
  private static ThreadLocal<Vector> vectors = 
new 
ThreadLocal<Vector>();
  public static Vector getVector(){
  Vector v = (Vectorvectors.get();
  if (v == null){
  v = new Vector();
  vectors.set(v);
  }
  return v;
  }
  private static Hashtable<Thread,Vector> hvectors = 
 
new Hashtable<Thread,Vector>();
  public static Vector getVectorPriorToJDK12(){
  Vector v = (Vectorhvectors.get(Thread.currentThread());
  if(v == null){
  v = new Vector();
  hvectors.put(Thread.currentThread(), v);
  }
  return v;
  }
