Hi friend,

import java.util.Collections;
import java.util.LinkedList;
import java.util.List;

public class Notify extends Object {
private List list;

public Notify() {
list = Collections.synchronizedList(new LinkedList());

public String rItem() throws InterruptedException {
synchronized (list) {
while (list.isEmpty()) {
print("done with wait()");
String item = (String) list.remove(0);

return item;

public void itemInert(String item) {
synchronized (list) {
print("added: '" + item + "'");


private static void print(String msg) {
String name = Thread.currentThread().getName();
System.out.println(name + ": " + msg);

public static void main(String[] args) {
final Notify nf = new Notify();

Runnable r1 = new Runnable() {
public void run() {
try {
String item = nf.rItem();
print("returned: '" + item + "'");
} catch (InterruptedException ix) {
} catch (Exception x) {
print("threw an Exception!!!\n" + x);

Runnable r2 = new Runnable() {
public void run() {

try {
Thread thread1 = new Thread(r1, "A");


Thread thread2 = new Thread(r1, "B");


Thread thread3 = new Thread(r2, "C");


} catch (InterruptedException x) {
