public int generateNumber(int random){
Random generator = new Random();
int a = generator.nextInt(random);
return random;
}

.equal()只判断值是否相等

package mathquiz;

import java.util.Random;
import java.util.Scanner;

public class QuizMain {

    public static void main(String[] args) {

        int score=0;
        int rounds=3;
        
        //add your code here
            QuizMain timu = new QuizMain();
           
            Scanner daan = new Scanner(System.in);
           boolean isvalid = false;
           while(!isvalid) {
        	   double cAnswer = timu.generateQuestion();
        	   while(!isvalid && !daan.hasNextDouble()) {
        		   String str = daan.next();     	   
        		   if(str.toLowerCase().equals("x")) {
        			   isvalid = true;  
        		   }
        	   }
        		   if(!isvalid) {
        		   double s = daan.nextDouble();
