Using interface-oriented programming in Java, which is for abstract programming, is a better way to reduce coupling ArrayList LinkedList is a sub-class of list, like Set is also collection sub-interface its implementation has HashSet LINKEDH Ashset TreeSet, etc. Many times in the work, we need to put many kinds of instance objects, all thrown into a set, this time we should find a standard, interface is a standard. Or it can be understood that many k

Java-linked list source code principle analysis, and build a queue through the consumer list, java-linked list Here we will introduce the simplest linked list listing; Let's take a look at the add () method: public boolean add(E e) { linkLast(e); return true; } void linkLast(E e) { final Node Th

In some cases, we need to do something about the list, such as multiplying each element in the list by 2, which is generally the traversal of each element multiplied by 2. Then it will be two lines to write it down. And this will modify the original list, if you want to not modify the original list, there are more than

Linked List CycleTopic linksTitle Requirements:Given A linked list, determine if it has a cycle in it.Follow up:Can you solve it without using extra space?Just see this problem, it is easy to write down the following procedure:1 BOOLHascycle (ListNode *head) {2ListNode *a = head, *b =head;3 while(a)4 {5b = a->Next;6 while(b)7 {8 if(A = =b)9 return tru

A series of questions about linked lists are described earlier, and here we introduce a more representative algorithm for the reversal of unidirectional lists. In the reversal of the time must remember the multi-drawing, more to understand when the list is reversed when it changes the address, this and the array of data is very inconsistent.　　 Publicnode reverselist (node head) {//determine if a linked list

Today, a website needs a function to import friends from MSN and email contacts. This function is also important, so that the website can obtain more user sources. I checked it online today and found a good open-source jar package that supports Java. This jar package supports mailbox Hotmail, Gmail, Yahoo, Sohu, Sina, 163,126, Tom, yeah, 189 and 139. And MSN contact Import, I did a test, the effect is very good, haha, all my MSN contacts are imported in. I would like to recommend it to you here.

Topic Connection: click~/* Test Instructions: Flips the list of points m through n *//** * idea: To better handle the header and the M nodes, introduce the root node and record the * m-1 node. Starting from the first node of M to the nth node, insert the already traversed node after the M-1 node and ensure that the next * of the M node points to the next of the traversal node to avoid a broken list
