true randomInt

[m3the01]

just wondering how you could produce a true random in, here is my code. Only thing is that everythime the random int is in the same order, first time 73 second time 10 and so on everytime i run my program






public class GuessingGame{

private RandomInt generator;
private int genNumber;
private IntValidator test;
private int uservalue;
private int guessCounter;


public GuessingGame(){

generator = new RandomInt(1);
genNumber = generator.next(99);


}

public void play(){

test = new IntValidator("Please guess a number between 1 and 99>"
uservalue = test.ask();
String correct = ("Congradulations, you guessed the correct answer,"


while(uservalue != genNumber){
if (uservalue > genNumber){
System.out.println("Your guess is too high,"
uservalue = test.ask();
guessCounter ++;
}
else{
System.out.println("Your guess is too low,"
guessCounter ++;
uservalue = test.ask();

}
}
guessCounter ++;
System.out.println(correct);
System.out.println(genNumber + " in " + guessCounter + " guesses"
genNumber = generator.next(99);
guessCounter = 0;
}




}

You should use the Random class within the java.util package. The method nextInt() can be used to generate a new random number as shown in the following code :

import java.util.Random;

class RandomNumbers {
public static void main(String [] args) {

int generatedNumber, i;

Random r1 = new Random();
// generate number between 0 and 99

for (i = 0; i < 10; i++) {
generatedNumber = r1.nextInt(100);
System.out.println(generatedNumber);
}
}
}

Each time the class file is executed it will generate ten new random numbers.

This will probubly still produce the same sequence of
randoms. Typically something like a true random is
achieved by using a seed value, usually current time.
Use the Random constructor with a seed value
Random(long seed)
Creates a new random number generator using a single long seed:

This will give a different value everytime.
