named, which expungeStaleEntries() Map is called in most operations, which removes all invalid references in the reference queue and deletes the associated mappings. expungeStaleEntries()a possible implementation is shown in Listing 7. The type used to store the key-value mappings is Entry extended WeakReference , so when the expungeStaleEntries() next invalid weak reference is requested, it gets one Entry . It is more efficient to use a reference queue instead of a regular scan of the content,

In Java development, we often encounter memory leaks. So why is there a memory leak and how to prevent it!Memory leak definition: Objects have not been used by the application, but the garbage collector is not able to remove them because they are still being referenced.Why t
expectation, occupy more than 90% of the memory. In general, char[] does take up a lot of memory in the JVM, as well as a very large number, because string objects are char[as internal storage. But this time the char[] too greedy, careful observation, found that there are tens of thousands of char[], each occupies hundreds of K of memory. This phenomenon indicat

Since its inception, more than 20 years ago, Java is still the most widely used language. This relies on the various technologies and features provided by Java, allowing developers to gracefully write efficient programs. Today, let's talk about a basic, but very important, technology in Java. Memory ManagementUnderstan
When you move from cc++ to a language with garbage collection, the programmer's work becomes easier because you run out of objects and they are automatically recycled, but do Java programmers really need to think about memory leaks? actually otherwise1.

The difference between Java memory leaks and overflowJava memory leak is not in time to clean up the memory garbage, causing the system can no longer provide you with memory resources (memory
the program code generates garbage, and it is likely that the garbage collector will not start at the end of the program. Therefore, the garbage collector does not completely avoid the problem of memory leaks. on the other hand, garbage collection brings additional burden and space-time overhead to system resources. The less likely it is to be activated, the less likely it will be to bring the burden. Ther
Memory management has always been a powerful advantage of Java's advocacy. Developers simply need to create objects, and Java's garbage collector will automatically manage the allocation and deallocation of memory space. But in many cases, things are not that simple, and memory leaks are always occurring frequently in

A memory leak means that an object or variable that is no longer being used by a program is occupied in memory. Java has a garbage collection mechanism that ensures that an object is no longer referenced, that is, when an object becomes orphaned, and the object is automatically purged from memory by the garbage collect
