Random numbers can be used in Java. Here's a small random number generator and how it works.

import java.util.Random;
class Class1{
	public static void main(String args[]){
		Random dice = new Random();
		int number;
 
		for(int counter = 1; counter <= 10; counter++){
			number = dice.nextInt(6) + 1;
			System.out.println(number);
		}
	}
}

First of all, we need to import the random class. Type import java.util.Random; at the top of your code. We then created an object to use this random numer and we named it dice. We made an integer named number to store this value. We then created a loop iterating ten times and each time it did we assigned number a new random number using our dice object. We did this by typing dice.nextInt(6) + 1;. The reason we've added one to the output is to prevent us from receiving numbers 0-5. We want numbers 1-6, so we simply add one to the output.
