Random numbers every so often

  • 772

Does anyone know how to generate random numbers every minute?

Right now I only have a for loop where it sends 3 pieces of data, nothing more, but it sends them instantly, and I need it to return a random number every minute.

for(int i =0; i<3; i++){      
int numero = (int) (Math.random() * 100) + 1;      
System.out.println(numero);     
}

Result is:

56
32
49

    You can use a call to to introduce a millisecond Thread.sleep()wait before getting the next number.n

    Sleepreceives the number of milliseconds that the calling thread will sleep before continuing its execution.

    Example, adapting your code, it could be:

    for(int i =0; i<3; i++){      
  int numero = (int) (Math.random() * 100) + 1;      
  System.out.println(numero);     
  Thread.sleep(60000); //60000 milisegundos son 1 minuto
}

    The output will be the same, but your program will deliver each number 1 minute after the previous one.

    One flaw in the code I'm sending you is that after delivering the last number, the program will wait a minute before exiting. This is not necessary, it remains as an exercise for you to adapt it so that it does not make that wait, if you wish.
