Adding a Wait or Delay to Java

March 15, 2023

So I have some Java code that once it has ran through that part, I want it wait/delay for some amount of time. Here is the code I have:

Trajectory exampleTrajectory =
        TrajectoryGenerator.generateTrajectory(trajectory);
        TimeUnits.Second.sleep(10)

I have tried using TimeUnits.Second.sleep(10) but I keep getting an error saying that it cannot be resolved.

>Solution :

Instead of:

TimeUnits.Second.sleep(10)

It should be:

TimeUnit.SECONDS.sleep(10);

Complete working example:

import java.util.concurrent.*;
class Main { 

  public static void main(String[] args) {
    System.out.println("a");

    try {
      TimeUnit.SECONDS.sleep(10); // 10 second delay
    }
    catch (InterruptedException e) {}
    
    System.out.println("b");
  }
  
}
