推荐答案

您的代码中有一个错误的递归循环。方法 main 调用 callMe ，然后调用 getData 。但是，当 getData 已收集其输入数据时，它又会调用 callMe ，然后调用 getData ，依此类推。

You have a bad recursive loop in your code. Method main calls callMe, which then calls getData. However, when getData has collected its input data, it, in turn, calls callMe, which then calls getData, and so on.
