Can't understand 2;56 - 3:09, the word FINAL

  1. It said that our answer label variable can't be reassigned? You mean the answerLabel TextView DataType's value? Like we assigned "Yes" and it can't be assigned again.

  2. Then, for the rest can you explain it more further. It said OnClick method must refer to same view as long as it exist (In this case our view will be textview right?)

3.WE can't make it update a different text view by reassigning the answer label variable to some other text view So does it mean, we have: String answer = "Yes"

and let say I has two variable of TextView TextView answerLabel; Text View Answer Label2;

onClick(){ //It can't do String answer = "Yes" answerLabel.setText(answer) answerLabel2.setText(answer); }

Am I correct?
