java - Using string literals in logger debug statement

Question

We often use loggers in our code for debugging purpose. We write something like this

logger.debug("");

My question is, doesn't it create lots of objects since we use String literals in debug statements so much? Is there any alternative to avoid it?

字符串字面量在共享池中分配，因此不会浪费空间。每个相等的字符串共享一个实例。

根据String.intern() ，文字是实习的。
