Can you ensure that ?



   class A {
      private Bar   bar;

      public A(Bar bar) {
         setBar(bar);
      }

      protected void setBar(Bar bar) {
         this.bar = bar;
      }
   }

   class B extends A {
      private Bar   bar;
      private Foo   foo;

      public B(Bar bar, Foo foo) {
         super(bar);
         this.foo = foo;
      }

      protected void setBar(Bar bar) {
         this.bar = bar;
         this.foo = bar.foo;
      }
   }

Will code have same effect when constructor will be :
      public B(Bar bar, Foo foo) {
         this.foo = foo;
         super(bar);
      }
