Concurrentmodificationexception of the Java list container

beginning, the deletion process does not update the iterator state, so the final state is inconsistent. First, take a look at iterator's delete code: Public BooleanRemove (Object o) {if(O = =NULL) { for(intindex = 0; index ) if(Elementdata[index] = =NULL) {fastremove (index); return true; } } Else { for(intindex = 0; index ) if(O.equals (Elementdata[index])) {fastremove (index); return true; } } return false; } Priva

Ordered container list vector

the container header, the vector is better than deque. List indicates a non-consecutive memory area, and uses a pair of pointers pointing to the beginning and end elements to link them in two directions, allowing traversal in the forward and backward directions. It is highly efficient to insert and delete elements at any position in the list: the pointer must be

Container Use Notes (List article)

poses a great risk to the program,and list requires explicit data types at the time of definition, so thelist is a strongly typed collection, and the advent of generics avoids data exchange and storage of fashion boxes and unpacking operations, greatly reducing memory loss. Its usage and ArrayList are basically the same. The code is as follows: Summary:Arrays: Arrays can store data in multiple dimensions, stored in the sequential table structure i

Differences between Java container class List, ArrayList, Vector, map, HashTable, and HashMap

ArrayList and HashMap are asynchronous, while Vector and HashTable are synchronous. Therefore, Vector and HashTable are thread-safe, while ArrayList and HashMap are not thread-safe. Because synchronization takes machine time, the execution efficiency of Vector and HashTable is lower than that of ArrayList and HashMap. Collection sorted List interface │ ordered List linked

Doing erase in the vector is done in the following steps:Copy ()Destory ();Erase operations in the list containerDestory ()Deallocate ()Vector use in a sense the memory space is only increasing "if not through a technology" and the list is like normal operation, the release is released without releaseMethod of vector reduction:Call swap this is the way to really release memory A.swap (b) method to free mem

Java container class list, arraylist, hashtable, hashmap

Arraylist and hashmap are asynchronous, while vector and hashtable are synchronous. Therefore, vector and hashtable are thread-safe, while arraylist and hashmap are not thread-safe.

Comparison of container class list, set, and map in Java

I haven't updated my blog for a long time, because I started to learn about Java programming ideas during this time. I hope I can have a deeper understanding of Java so that I can process androidProgramIt can be handy. Today, when I saw containers in Java, I found some useful things, that is, the comparison of various containers in Java and the conditions for using various containers. I would like to share with you here. This blog is not intended to add descriptive text. It mainly involves seve
