What will be the result after the class Test execution?

class A{
      public void doA(){
            B b = new B();
            b.dobB();
            System.out.print("doA");
      }
}
class B{
      public void dobB(){
            C c = new C();
            c.doC();
            System.out.print("doB");
      }
}
class C{
      public void doC(){
            if(true)
            throw new NullPointerException();
            System.out.print("doC");
      }
}
public class Test{
      public static void main(String args[]){
            try{
                  A a = new A();
                  a.doA();
            }catch(Exception ex){
                  System.out.print("error");
            }
      }
}
