Quick Question.

I am going through the article for String vs StringBuilder. I have couple of doubts

1.Which is better to use ( String or StringBuilder ) for strings that change constantly. Please explain why ( I think it is String. Correct me if I am wrong )
2. For large strings which is a good option ( I think it is StringBuilder )
3.Is string type optimized to accept changes without much impact ?

The following article will clear your doubts:

I went through the article. That clarifies the first question of mine. if you try to do some other manipulation (like removing a part from the string, replacing a part in the string, etc.), then it's better not to use StringBuilder at those places. This is because we are anyway creating new strings. So that means for strings that change constantly it is better to use String instead of StringBuilder.

I couldnt find anything which clarifies my Questions 2 and 3

Question 2: I do not think the size of a string matters.
Question 3: A string is immutable: it cannot be changed. A new string is always created for concaternation,replace etc. So there is no question of optimization here.
Ultimately, it all falls back to question 1, to help you with more in-dept understanding, check these out

StringBuilder is used for strings that change constantly. - False
StringBuilder should be used only with big enough strings - True
String type is optimized to accommodate changes without much impact. --> False ( As we are creating new string everytime for every change i think its not optimized )
Let me know if my understanding is correct
