Java is ignoring an if statement, and if not it's not working [closed]

static void start() {
    Scanner sc = new Scanner(System.in);
    
    System.out.println("\nYou're going to play a guess number game.");
    System.out.println("\nPlease type in a minimum value.\n");
    min = sc.nextInt();
    System.out.println("\nThe value you entered is "+min);
    System.out.println("\nPlease type in a maximum value.\n");
    max = sc.nextInt();
    System.out.println("\nThe value you entered is "+max);
    if (min>max) {
        
        System.out.print("\nYou entered a maximum value lower then the minimum value, please try again.");
        start();
        
    }else if (min>=max-9) {
        
        System.out.print("\nYou must have a maximum be 9 more than the minimum, please try again.");
        start();
        
    }
        
    number = (int)(Math.random() * (max - min + 1) + min);
    System.out.println("\nPlease pick a number, "+min+"-"+max+".\n");
    guess = sc.nextInt();
    checkGuess();       
    
}

In the code, everything works except for the if statement checking to see if the minimum value and the maximum value are at least 9 numbers apart.

I use Eclipse IDE and Java-14.
