How to Write a Blurb With a Java Program
One thing a programmer can do with Java is present textual information to the user, either in a terminal or through a Graphical User Interface (GUI). Whichever way, the internal logic of the program is rather simple: create a list of strings to present ("blurbs") and set them to display randomly on a timer. In this way, you can cycle through the blurbs randomly, and keep the blurbs appearing on the screen.

Set up a Blurb class. This class will contain a String array, which will contain the blurbs, as well as a counter to count the number of blurbs:
import java.io.*;
import java.util.Random;class Blurb{
String[] blurbs = new String[20];
int count = 0;
public static void main(String args[]){
}
} -

Create a list of blurbs in an array:
public static void main(String args[]){
blurbs[0] = "blurb 1";
blurbs[1] = "blurb 2";
blurbs[2] = "blurb 3";
blurbs[3] = "blurb 4";count = 4; //four blurbs
}

Generate a random number in the main program:
Random r = new Random(); //random number up to

Cycle through the blurbs at short intervals, using a random number each time:
for (int i = count; i < count; i++){
int current = r.nextInt(count); //random number between 0 and 3
System.out.println(blurbs[current]);Thread.sleep(10000); //pause for ten seconds
