This may be one of the reasons for the pervasive belief that object allocation is expensive-earlier jvm implementations did not use copying collectors, and developers are still implicitly assuming allocation cost is similar to other languages, like c, when in fact it may be significantly cheaper in the java runtime 以前的jvm实现没有使用复制收集器这可能是对象分配是昂贵的这一想法是如此普遍的原因之一,开发人员仍然下意识地假设分配成本与其他语言(如c)类似,而事实上在java运行时中可能要廉价得多。
