Java - Tutorial #3 [Random Number Generator]
Posted: Wed May 22, 2013 11:16 am
Beginner? to code in java you need an IDE to make it easier and I prefer you get Eclipse, the best one so far, compile and run your java projects with a user-friendly GUI.
Objective: Printing a a random number message into the console.
so first of all you need to start Eclipse then start a new Project name it anything you like, then click Next - finish now, right-click on your java project in the explorer, then add new class. for now, name it tutorial.
then open the new class and insert this code:
First we imported a Random so this works, then we added a new random called "rand" and added an integer called number
then we just did a simple method to get 10 random numbers,below 6 and we just printed them using the println method.
Yup its just that easy
, and you need to play with it, change numbers and stuff , that way you can learn more than tutorial, just play with it :lol:

Explaination:
import java.util.Random;
class tutorial{
public static void main(String[] args) {
Random rand = new Random();
int number;
for(int counter=1; counter<=10;counter++) {
number = rand.nextInt(6);
System.out.println(number + " ");
}
}
