StringBuffer came first. Sun was concerned with correctness under all conditions, so they made it synchronized to make it thread-safe just in case. StringBuilder came later. Most of the uses of StringBuffer were single-thread and unnecessarily paying the cost of the synchronization.Since StringBuilder is a drop-in replacement for StringBuffer without the synchronization, there would not be differences between any examples0ReplyLeave an answerLeave an answerCancel reply Select file Browse Save my name, email, and website in this browser for the next time I comment.
