Introduction:
Java multithreading introduces complexity and challenges, particularly when it comes to maintaining order and avoiding race conditions. In this comprehensive blog post, we will delve deeper into three critical methods — sleep, wait, and notify — unraveling their intricacies with a focus on practical code examples.

Thread.sleep() Method: A Pause in Time:
At first glance, the Thread.sleep() method might seem simple — an easy way to introduce a pause in thread execution. However, beneath its surface lies a crucial understanding of its impact on concurrency.

// Example: Sleeping for 1 second
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}

While seemingly straightforward, developers must be aware that using Thread.sleep() can affect the overall performance and responsiveness of a multithreaded application. It’s essential to carefully choose the duration of sleep to strike the right balance between responsiveness and resource utilization.

Extending our discussion on Thread.sleep(), let’s explore its role in scenarios where threads interact with external resources or systems. For instance, in…
