“StringBuffer”造句，怎麼用StringBuffer造句

明確了這個基準測試的單線程化的本質後，我期待着逸出分析會消除鎖，從而將StringBuffer的*能提到了與StringBuilder相同的水平。

舉例來說，考慮一下線程安全的StringBuffer的用法。

Given the single threaded nature of this benchmark, I was fully expecting Escape Analysis to elide the lock thus rendering StringBuffer performance equivalent to that of StringBuilder.

爲創建串聯的字元串 “ssRights” ，編譯器將創建一個臨時的StringBuffer對象，調用StringBuffernd 三次，然後調用StringBufferring ，這意味着至少兩個對象的創建和幾個方法調用。

對String和StringBuffer來說，完成測評所需要的時間隨着計劃長度的增加呈指數級增長。

However, there is a performance penalty here, since a StringBuffer must work to transparently increase its size and shift the data around.
