I've made a simple game with 2 classes. It uses a scanner and when I try it it says java.util.NoSuchElementExeption. It also says the errors are on row 19 in RNGlog and 24 in RNG. Please help
First class: RNG
public class RNG {
public static void main(String[] args) {
RNGlog log = new RNGlog();
int max = log.max();
int min = log.min();
double counter = 3;
//Variables outside of loop
System.out.println("Write a number between " + max + " and " + min + ".");
System.out.println("If your number is higher than " + max + ", it will be " + max + ". Vice versa for " + min + ".");
System.out.println("If your number is higher than the random number, you win credits!");
System.out.println("You start with 2 credits.");
System.out.println("You lose if you hit 0 credits. Good luck!");
//Introduction
while(counter > 0) {
//Loop start
double r = Math.random() * 10;
float in = log.getIn(); //Error here
//Random number generator, input
double credit = 6 - in;
//Credit Win generator
if(in > r) {
counter = counter + credit;
//Counter refresh
System.out.println("Great job! The number was " + r + ".");
System.out.println("You won " + credit + " credits. Nice.");
System.out.println("Credit counter:" + counter + ".");
//Winning messages
}
else {
counter = counter - 1;
//Counter refresh
System.out.println("Nearly, n00b! It was " + r + ", how did u no realize.");
System.out.println("You lost 1 credits!");
System.out.println("Credit counter:" + counter + ".");
//Losing messages
}
if(counter <= 0) {
System.out.println("Game over! Better luck next time.");
//Game ender
}
}
}
}
Second class: RNGlog
import java.util.Scanner;
public class RNGlog {
int max() {
int max = 6;
return max;
}
int min() {
int min = 0;
return min;
}
float getIn() {
Scanner scan = new Scanner(System.in);
float imp = scan.nextFloat(); //Error here
if(imp < min()) {
imp = min();
}
//Stops number lower than 0
if(imp > max()) {
imp = max();
}
//Stops numbers higher than 6
scan.close();
return imp;
}
}
Would be really apriciated if someone could help!
