Any reason why preference for mutator using void

[invisible.hippo]

something like

void setstring1(string);

I have an assignment state to use in this form. However i have no idea why does it need to be like(in terms of benefits)

Thank you

You are setting value into an entity, do you have a need to return value from the operator ? Most assignment do not need to return anything.

However, there are some encapsulation design that return the object while you are building the contents so that you can daisy chain, like this

List mylist = new List();

mylist.add(obj1).add(obj2);

There are also some cases where setting something can return the same type as the arguments to indicate spill over or conflict.

For eg:

Set myset = new Set();
oldvalue = myset.put(key, newvalue);

depending on whether there is a conflict where the oldvalue may be NON-NULL

There are also cases, where it return a true/false value to indicate success of the operation.

There is no definite approach to this, it goes with the intended need.

No i dont need to daisy chain

Reply you, thanks

Go figure it out.

You want to be more appreciative in your response and learn to have a dialogue that shows you are learning and thinking, not you know or you don't know.

I don't get why I should feed you further. You will want to tell me know what do you not understand.

Response you too. Thanks
