kotlin sleep

The Thread.sleep() function in Kotlin is used to pause the execution of a program for a specified amount of time. It is commonly used to introduce delays or pauses in a program's execution.

Here is a step-by-step explanation of how to use Thread.sleep() in Kotlin:

1. Import the necessary package: Before using the Thread.sleep() function, you need to import the Thread class from the java.lang package. This can be done using the following line of code:

import java.lang.Thread

1. Call the sleep() function: To pause the execution of your program, you need to call the sleep() function on an instance of the Thread class. The sleep() function takes a single parameter, which specifies the duration of the pause in milliseconds.

Thread.sleep(1000)

In the example above, the program will be paused for 1000 milliseconds, which is equivalent to 1 second.

1. Handling InterruptedException: The sleep() function can throw an InterruptedException if the thread executing the sleep is interrupted. To handle this exception, you can use a try-catch block.

try {
    Thread.sleep(1000)
} catch (e: InterruptedException) {
    // Handle the exception here
}

By wrapping the sleep() function call in a try-catch block, you can handle any potential interruptions gracefully.

That's it! These are the steps to use the Thread.sleep() function in Kotlin to introduce delays in your program's execution. Remember to import the necessary package, call the sleep() function with the desired duration, and handle any potential InterruptedExceptions that may occur.
