My Java Code isn't producing results for the "while" loop

Question

Please have a look at the code below:

I have tried other basic codes like "Hello World", Strings, and variables which are giving results but not this one for some reason.

public class App {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        int num = 1;

        while(num < 10);
        {
            System.out.println("Hello" + " " + num);

            num = num + 1;
        }
    }

}
