You can use the Random in this way

public int numeroAleatorio(int min, int max){

    Random rand = new Random();
    int randomNum = rand.nextInt((max - min) + 1) + min;

    return randomNum;
}

Or use the Class Math

public int numeroAleatorio(int min, int max){
    int randomNum = min + (int)(Math.random() * (max - min));

    return randomNum;
}
