而 Java 中的WeakReference主要用于防止内存泄漏，允许对象在内存不足时被回收。C++ 通过引用计数进行内存管理，而 Java 依赖于垃圾回收机制。扩展：为什么C++能实现std::shared_ptr类似的智能指针呢？它没有Java那样的jvm内存管理机制。std::shared_ptr使用引用计数来管理资源的生命周期。当一个std::shared

I don't know why the compiler complains about the ternary operator: "not a statement". I understand I can convert it into an if-else statement.
