• Waiting state
- Example: Using the wait method inside a synchronized block, a thread can wait until another thread calls
the notify() or notifyAll() methods to wake it up.

- Use case: Implementing the producer-consumer pattern, where a thread waits for a specific condition to
be met before continuing its execution
• Timed waiting state
- Example: Using methods like sleep(milliseconds) or join(milliseconds) causes a thread to enter the timed
waiting state for the specified duration.
- Use case: Adding delays between consecutive actions or waiting for the completion of other threads
before proceeding.
• Terminated state
- Example: When the run() method finishes its execution or when the stop() method is called on the Thread.
- Use case: Completing a task or explicitly stopping a thread’s execution.

Example: Thread Life Cycle in Java:
Here’s an example that demonstrates the life cycle of Thread in Java:
public class ThreadLifecycleExample {
public static void main(String[] args) {
Thread thread = new Thread(() -> {
System.out.println(“Thread is running.”);

try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();

}
System.out.println(“Thread is terminating.”);
});
System.out.println(“Thread is in the New state.”);
thread.start();

System.out.println(“Thread is in the Runnable state.”);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {

e.printStackTrace();
}
System.out.println(“Thread is in the Timed Waiting state.”);
try {
thread.join();
} catch (InterruptedException e) {

e.printStackTrace();
}
System.out.println(“Thread is in the Terminated”);
