Exception not being executed

Im constructing a program in which the user inputs a height between 3 and 10 and a triforce from zelda is printed in java. At the current moment, whenever the user inputs numbers outside that range an exception is thrown, however I want the program to throw an exception whenever any string is inputted. Im not sure how to utilise the InputMismatchException. This is my code so far:

public static void main(String[] args) {

    Scanner keyboard = new Scanner(System.in);
    int height;

    try {
        System.out.print("Enter height: ");
        height = keyboard.nextInt();
        }

    catch (InputMismatchException e) {
        System.out.println("");
        System.out.println("Invalid height.");
    }

    if (height < 3 || height > 10) {
            System.out.println("Invalid height.");
            System.exit(0);
    }

try {
    System.out.print("Enter height: ");
    height = keyboard.nextInt();

    if (height < 3 || height > 10) {
        System.out.println("Invalid height.");
        System.exit(0);
    }
    // print triforce from zelda
    // ...
} catch (InputMismatchException e) {
    System.out.println("please input a int");
}
