Preface G1 GC, the full name of Garbage-First Garbage Collector, is enabled through the -XX:+UseG1GC parameter. As a trial version, it was released with the JDK 6u14 version and was officially launched when the JDK 7u4 version was released. I believe that students who are familiar with JVM No one will be unfamiliar with it. In JDK 9, G1 is proposed to be the default garbage collector (JEP 248). On the official website, G1 is described like this: The Garbage-First (G1) collector is a server-style garbage collector, targeted for multi-processor machines with large memories. It meets garbage collection (GC) pause time goals with a high probability , while achieving high throug

2. Detailed introduction to the stack
Introduction: Java's heap is a runtime data area, from which class (objects allocate space. These objects pass new, newaray Instructions such as , anewarray and multianewarray are established. They do not require program code to explicitly release. The heap is responsible for garbage collection. The advantage of the heap is that it can dynamically allocate memory size, and the lifetime does not need to be told to the compiler in advance, because it Memory is dynamically allocated at runtime, and Java's garbage collector will automatically collect the data that is no longer used. However, the disadvantage is that since memory must be dynamically allocated at runtime, access...

##Introduction: Java The heap is a runtime data area from which objects of classes are allocated space. These objects are created through instructions such as new, newaray, anewarray and multianewarray, and they do not require program code to be explicitly released. The heap is responsible for garbage collection The advantage of the heap is that it can dynamically allocate memory size, and the lifetime does not need to be told to the compiler in advance, because it dynamically allocates memory at runtime, and Java's garbage collector will automatically collect the data that is no longer used. But there are disadvantages. Yes, because memory needs to be dynamically allocated and accessed at runtime...

7. Those things about Java GC (1)
Introduction: Unlike the C language, Java memory (heap memory) is allocated and recycled by the JVM The garbage collector is automatically completed. This feature is very popular and can help programmers write better code. This article uses the HotSpot virtual machine as an example to talk about Java GC. In the article about Java heap memory in JVM memory, we already know that the Java heap is a memory area shared by all threads, all object instances and arrays
8. Java Virtual Machine Learning - Garbage Collector
##Introduction: The Serial collector is a new generation collector. Threaded execution, using a replication algorithm. It must suspend all other worker threads (user threads) while performing garbage collection. It is the default new generation collector in Jvm client mode. For an environment limited to a single CPU, the Serial collector has no thread interaction overhead, so it can naturally achieve the highest single-thread collection efficiency by focusing on garbage collection.
9. Detailed explanation of the function of Java garbage collection finalize()
Introduction: Java technology allows the use of the finalize() method to do necessary cleanup work before the garbage collector clears the object from memory. This method is used by the garbage collector when it determines that the object is not referenced. object called.
