references

Java four types of references include strong references, soft references, weak references, and virtual references.Strong references:The garbage collector will never recycle as long as the reference existsObject obj = new Object (); The

In Java strong reference, soft reference, weak reference and Virtual Reference original link: http://aaronfu.net /? P = 9995 Since jdk1.2, the object reference is divided into four levels, so that the program can control the object lifecycle more

The so-called memory leak, is actually the object in the time of the recovery is not properly recycled, the memory of these wild pointers. So it's important to understand these kinds of citation patterns and use it with the Great God's blog.Reprint:

Strong references, soft references, weak references, virtual referencesLet's talk about the garbage collection mechanism gabagecollection:GC is the meaning of garbage collection (gabagecollection). Like Java, the Android system is also powered by GC

As we all know, Java is the JVM responsible for the allocation and recycling of memory, which is its advantage (easy to use, the program no longer like using C as the memory), but also its shortcomings (not flexible). In order to solve the problem

1. Strong, soft, weak, and virtual references to objectsIn previous versions of JDK 1.2, if an object was not referenced by any variable, the program could no longer use the object. That is, only the object is in the accessible (reachable) state

Knowing the concepts of weak references and soft references are different from how they are used, and referencing classes play an important role in the process of garbage collection. We all know that the garbage collector reclaims the memory of
