在Eclipse中，是否可以找到在哪里调用了某个函数，类或变量？

Question

When you want to open the declaration of a class/function/variable in java you can press Ctrl and click on it, but is there are way to go the other way round? If you had to find all instances where a function or variable is called how would you quickly get that?

Answer 1

Ctrl + Alt + H向您显示使用或调用变量或方法的所有位置。

Answer 2

On both Windows and Mac, right-click the method, and choose "Open Call Hierarchy."

You can use this for identifiers other than methods. For example, if a class does not have an explicit constructor, you can use this to find all the callers of its default constructor.
