首先项目初期能用就行, finalize()被诟病的一些低效率瓶颈初期真的遇不上, 其次它真的很好用, 只需提供一个JNI删除内存/减少ref count的函数, 在Java部分直接用就行, 如下: private volatile long m_native_pointer = 0; public void close() throws Exception { System.out.println("FinalizableNativePointer...
Physical address = base address+ offset = (frame # * frame size) + offset Page size = frame size Logical address space (/size) = 2m Physical address space (/size) = 2x (where x is the number of bits in physical address) Logical address space (/size) = # of pages × page size P...
通常当我们分配一块原生内存(native memory)的时候, 我们在汇编/C/C++那边声明一块内存, 然后通过Java Native Interface(JNI, Java本地接口)给Java提供一个long类型的指针long m_native_memory_ptr;保存这个内存的地址. 并且我们可以写一些其他JNI接口对这块内存做一些操作和获取返回信息. 为什么我们要管理原生内存(n...
Memory Management in Java - Java Garbage Collection Java Garbage Collection is the process to identify and remove the unused objects from the memory and free space to be allocated to objects created in future processing. One of the best features of Java programming language is theautomatic garbage...

You might think that if you are programming in Java, what do you need to know about how memory works? Java has automatic memory management, a nice and quiet garbage collector that works in the background to clean up the unused objects and free up some memory. ...
