using 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

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:

1. Strong citation (Strongreference)Strong references are the most commonly used references. If an object has a strong reference, the garbage collector will never recycle it. As follows:Object o=New object (); // Strong ReferencesWhen there is

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

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

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
