Already learned the HashMap source code and Hashtable source code, today began to learn Linkedhashmap. The reference JDK version is 1.8. Linkedhashmap inherits HashMap, is the Map interface hash table and link list implementation. The function of

First, prefaceRead the excellent source code, the promotion of their own is very fast, whether it is to consider the angle of the problem, or coding ability.With the problem read the source, learning more efficient, you can temporarily set a few

(a) List:ArrayListImplemented as an array. Space-saving, but the array has a capacity limit. Exceeding the limit adds 50% capacity and is copied to the new array with system.arraycopy (), so it is better to give a pre-estimate of the size of the

In the shortest possible space, the features, implementations, and performance of all collections and concurrent collections are smoothed over. For all "proficient in Java" is actually not so confident people read.Constantly updated, please try to

Overview: Garbage collection is primarily done by reference counting, which means that when an object is not referenced by another object, it frees up memory. But there will be some circular reference objects, through the above method, there is no

ObjectiveMySQL currently supports the transaction engine with INNODB,TOKUDB. After Rocksdb joined the MySQL camp, MySQL supported a transaction engine that grew to 3.The transaction isolation levels currently supported by Myrocks are read-committed

The nodes of a single linked list have only one pointer to the next nodeData elements of a single linked list cannot directly access their precursor elementsReverse-order access to elements in a single-linked list is an extremely time-consuming

Definition of a linked listBefore you discuss a linked list, say the linear table first.A linear table is one of the most common and simplest data structures. A linear table is a finite set of n data elements. For a non-empty linear table, there are
