Loosen Constructor super()/this() call restrictions (original) (raw)

Hi,

I am not understanding your example, what is Bar if its not B - where is its definition.

Also my suggestion isn't saying that the super constructor can't access the super class fields or that after calling super you can't access super fields, just that before calling super you can't access super fields (only this.field_name). Also note that you can't call an instance method, at all, before super, not even this.method_name( ... ).

Howard.

I don't get the example. Is class B meant to be Bar? Can you clarify?

-- Howard. No, B is B. I wanted show the problem: public B(Bar bar, Foo foo) {  super(bar);  this.foo = foo; } mean in runtime:  this.bar = bar;  this.foo = bar.foo;  this.foo = foo; public B(Bar bar, Foo foo) {  this.foo = foo;  super(bar); } mean in runtime:  this.foo = foo;  this.bar = bar;  this.foo = bar.foo; While second constructor look really innocent. -- Pozdrowionka. / Regards.
