Java 实现 下述代码为小顶堆的实现,大顶堆的实现也是一样的,区别就是上浮和下沉操作的交换逻辑与小顶堆相反。 java packageDataStructure;importjava.io.Serializable;importjava.util.NoSuchElementException;publicclassMinHeap<E>implementsSerializable{privatestaticfinalintDEFAULT_INITIAL_CAPACITY =11;transientObject[]...
Java Heap 对于大多数应用来说,Java堆 (Java Heap) 是Java虚拟机所管理的内存中最大的一块。Java堆是被所有线程共享的一块内存区域,在虚拟机启动时创建。此内存区域的唯一目的就是存放对象实例,几乎所有的对象实例都在这里分配内存。根据Java虚拟机规范的规定,Java堆可以处于物理上不连续的内存空间中,只要逻辑上是...
不同的实现比较:https://en.wikipedia.org/wiki/Heap_(data_structure) 当你提到“堆” 的时候,不要默认认为是二叉堆,同时你要知道堆的实现又很多种,而二叉堆本身的话只是因为它相对比较容易实现,它的时间效率是堆里面算比较差的。 二叉堆的性质 通过完全二叉树来实现(注意:不是二叉搜索树); 什么是完全二叉树...

Here are two applications: keap-based PriorityQueue as a replacement of java.util.PriorityQueue and Keapsort sorting algorithm. Both might be useful in two cases: stability is a must; comparing elements is rather heavyweight operation (e.g., it requires a database access). PriorityQueue PriorityQu...
