positive/negative integer/float

[sherry12]

want to check whether user enters the number is positive integer or negative integer or positive float or negative float there is no error in the code but after entering the value it is not giving me any output as it stuck on the running state


public static void main(String[] args) {
Scanner input = new Scanner(System. in);
System.out.prin t("Please input a number:");
double number = input.nextDoubl e();
if (number >0 && input.hasNextIn t()){
System.out.prin tln(number +" is a positive, integer number.");
}

else if (number< 0 && input.hasNextIn t()){
System.out.prin tln(number +" is a negative, integer number.");
}

else if (number > 0 && input.hasNextFl oat()){
System.out.prin tln(number +" is a positive, floating number.");
}

else if (number< 0 && input.hasNextFl oat()){
System.out.prin tln(number +" is a negative, floating number.");
}



}
}

It giving the output after entering any number second time because scanner class methods hasNextInt and hasNextFloat method are check if the next token in this scanner's input can be interpreted as an int value using the nextInt() method or as a float value using the nextFloat() method.
