I want java to give me random number and user will try to guess it, if the user tries to enter an invalid data type, it will say: "Invalid Input. Integer only. Try Again" and will continue the code, but the code is not pushing through after showing the message even though it has while loop.
My whole chode:
import java.util.*;
public class tine {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
Random ranNum = new Random();
boolean Win = false;
int nAttempt = 0;
int number = (int)(Math.random()*50 );
int userInput;
System.out.println("Guess a number from 1-50!");
while (Win == false) {
nAttempt++;
try {
userInput = sc.nextInt();
if (userInput < number && userInput >= 1) {
System.out.println("too low.");
}
else if (userInput > number && userInput <= 50){
System.out.println("too high");
}
else if (userInput == number) {
System.out.println("you got it right in " +nAttempt +" attemp(s)");
Win = true;
}
else {
throw new InvalidInputException();
}
}
catch (InputMismatchException im) {
System.out.println("Invalid Input. Integer only. Try Again");
userInput = sc.nextInt();
nAttempt--;
}
catch (InvalidInputException iie) {
System.out.println("Number is out of range. Try Again.");
userInput = sc.nextInt();
nAttempt--;
}
}
}
}
class InvalidInputException extends Exception {
InvalidInputException(){
super();
}
}
