Java if statement terminated error

I tried to create basic number find game (1-100). But always the program terminated after second try.

Code:

Random rnd = new Random();
int rndm  = rnd.nextInt(100);

int tryn;
Scanner sc = new Scanner(System.in);
System.out.print("Guess: ");
tryn = sc.nextInt();

if (tryn == rndm) {
        System.out.println("You win.");
        sc.close();
    }
    else if (tryn > rndm) {
        System.out.println("Too high.");
        System.out.print("Guess again: ");
        tryn = sc.nextInt();
    }
    else {
        System.out.println("Too low.");
        System.out.print("Guess again: ");
        tryn = sc.nextInt();    
    }

When I run output like:

<terminated> test2 [Java Application]...
Guess: 30
Too low.
Guess again: 50

Why my program doesn't loop? Thanks for any help.
