Java 数组销毁
如果我使用“Array_Name[] = NULL”，java的垃圾收集器会收集数组的其余部分吗？
If I use "Array_Name[] = NULL", does the garbage collector of java collect the rest of the array?

仅当
Array_Name实际上一开始就引用了一个数组。并且仅当没有其他对该数组的引用时。并且它只会回收数组中未被数组外部任何内容引用的元素。而且只有当它想要解决它时才会这样做:-)（语法
Array_Name[] = NULL并没有真正的意义。但我假设你做了类似的事情：考虑到我上面描述的条件，这可能使数组成为垃圾收集的正确目标。）
Only if
Array_Namehad actually been referencing an array to begin with. And only if there are no other references to the array. And it will reclaim only those elements of the array which aren't referenced by anything outside of the array. And it will only do so when it feels like getting around to it :-)(The syntax
Array_Name[] = NULLisn't really meaningful. But I'm assuming you'd done something like:This might make the array a proper target for garbage collection, given the conditions I described above.)
我同意 Dan 上面提到的所有内容，但实际上您可以通过调用 System.gc() 手动触发垃圾回收。当然，如上所述，这只会收集不再被其他任何东西引用的对象。
I agree with everything Dan mentioned above but you can actually trigger garbage collection manually by calling System.gc(). Of course as mentioned this will only collect objects that are no longer referenced by anything else.
