Explanation
I'm pretty sure there are multiple ways to get this done but what's the simplest recommended way to insert a wait-time before executing the next code?
Below is a simple Hello World code and I've added few comments to make it easier to understand and visualize :)
Code
/* HelloWorld.java */
public class HelloWorld
{
    public static void main(String[] args) {
        //Code 1
        System.out.println("Hello World!");
       //Some Code which will wait 10 seconds before executing the next line.
        //Code 2
        System.out.println("Hello Again, We Meet After 10 Seconds!");
    }
}
