public class TestDemo {
    
    public static String output = "";
    
    public static void main(String[] args) {
        foo(0);
        foo(1);

    }

    private static void foo(int i) {
        try {
            if(i == 1){
                throw new Exception();
            }
        } catch (Exception e) {
            output += "2";
