## 垃圾回收机制
### 标记清除算法(Mark-Sweep)
标记清除算法是最基础的垃圾回收算法,也是现在所有垃圾回收器的基础。分为两个阶段,第一阶段从根集合开始扫描,标记所有可达对象;第二阶段再扫描整个堆,把未标记的对象释放掉。
### 复制算法(Copying)
复制算法将内存分为两块相同大小的区域,每次只使用其中一块,在垃圾回收时,将正在使用的内存中的存活对象复制到未使用的内存块中,然后清除正在使用的内存块,并交换两个内存块的角色。
### 标记整理算法(Mark-Compact)
标记整理算法类似于标记清除算法,但是不是直接对未标记对象进行清理,而是让所有存活对象往一端移动,然后直接清理掉端边界以外的内存。
### 分代收集算法(Generational Collection)
分代收集算法将内存划分为几块,根据对象存活周期的不同将内存划分为几块。一般是把Java堆分为新生代和老年代,这样我们就可以根据各个年代的特点采用最适当的收集算法。在新生代中,每次垃圾回收时都发现有大批对象死去,只有少量存活,那就选用复制算法,只需要付出少量对象的复制成本就可以完成收集。而老年代中因为对象存活率高、没有额外空间对它进行分配担保,就必须使用“标记-清理”或者“标记-整理”算法来进行回收。
### 内存分配策略
对象优先在Eden区分配。当Eden区没有足够空间进行分配时,虚拟机将发起一次Minor GC。Survivor区用于从Eden区拷贝过来尚未死去的对象。
大对象直接进入老年代。大对象指需要大量连续内存空间的java对象。如很长的字符串以及数组。
长期存活的对象将进入老年代。虚拟机给每个对象定义了一个年龄计数器。如果经过一次Minor GC仍然能够存活,则将其年龄+1。当超过一定年龄(默认15岁)时,将会进入老年代。
动态年龄判定。虚拟机并不要求Survivor区域中的年龄必须达到MaxTenuringThreshold才能晋升老年代,如果Survivor空间中相同年龄所有对象大小总和大于Survivor空间的一半,年龄大于或等于该年龄的对象可以直接进入老年代。
