4 个答案

• 答案 1：

  谁告诉你慢了？

• 答案 2：

  忽略不计

• 答案 3：

  应该动态加载的，没办法运用jvm的一些优化措施，比如jit之类的。

• 答案 4：

  Because reflection involves types that are dynamically resolved, certain Java virtual machine optimizations can not be performed. Consequently, reflective operations have slower performance than their non-reflective counterparts, and should be avoided in sections of code which are called frequently in performance-sensitive applications. stackoverflow.com/question...
