Q2. Is it preferable to use stringBuffer with its synchronized methods or stringBuilder when implementing toString() method? why?

Ans.

Use stringBuilder for toString() method as it is faster and not thread-safe.

stringBuilder is faster than stringBuffer as it is not thread-safe
toString() method is used for converting an object to a string
If thread-safety is required, use stringBuffer instead
Example: StringBuilder sb = new StringBuilder(); sb.append("Hello"); sb.append("World"); return sb.toString();
