random in range double java

Could you please tell me why I can't make a random double like a random int? When I try to random double? I tried with many options, but everytimes it does not work It's get a error: nextDouble() in java.util.Random cannot be applied to ('double'):

Thanks for advance!

public static int generateRandomInRange (int start, int finish){
    Random rnd = new Random();
    int numberR = rnd.nextInt(finish + 1 - start) + start;
    return numberR;

}
public static double generateDoubleRandomInRange (double start, double finish){
    Random rnd = new Random();
    Double numberD = rnd.nextDouble(finish + 1 - start) + start;
    return numberD;

}
