heap-memory

问题 I'm reading a book which says: The variable representing an struct instance doesn’t contain a pointer to an instance; the variable contains the fields of the instance itself. Because the variable contains the instance’s fields, a pointer doesn’t have to be dereferenced to manipulate the instance’s fields. The following code demonstrates how reference types and value types differ class SomeRef { public Int32 x; } struct SomeVal { public Int32 x; } static void ValueTypeDemo() { SomeRef r1 = new

问题 Well this is the error I get: Out of memory: Java heap space. Please assign more memory to Gradle in the project's gradle.properties file. For example, the following line, in the gradle.properties file, sets the maximum Java heap size to 1,024 MB: <em>org.gradle.jvmargs=-Xmx1024m</em> and it is because of: implementation 'nl.bravobit:android-ffmpeg:1.1.7' when I remove that the error gets gone.Well the error is saying increase the heap size to 1024MB and I did increase it to 10GB it's not

问题 I was creating this simple test program to demonstrate the way alignment works when allocating memory using standard new... #include <iostream> #include <iomanip> #include <cstdint> // // Print a reserved block: its asked size, its start address // and the size of the previous reserved block // void print(uint16_t num, uint16_t size_asked, uint8_t* p) { static uint8_t* last = nullptr; std::cout << "BLOCK " << num << ": "; std::cout << std::setfill('0') << std::setw(2) << size_asked << "b, ";

问题 I have a Springboot Maven project that uses a @JmsListener to read messages from a queue. If no events are coming in, the heap memory slowly increases. When messages are coming the heap memory is ramping up fast. But the heap memory never comes down (check image below). If I add System.gc() atthe end of the receiver method The garbage collector is doing its job as expected. But this is definately not good practice. How can I ensure that gc will runn at appropriate times. Any help would be
