or deleting some elements). When calling the iterator method, concurrentmodificationexception is thrown. Therefore, this exception must be caught. Stack Stack inherits from vector to implement a post-import, first-out stack. Stack provides five additional methods to make the Vector used as a stack. The basic push and pop methods also include the elements of the peek method to get the top of the stack. The

This article will share with you how to use raphael. js to complete map interaction, raphael. javascript is a small javascript library that allows you to draw various vector graphs, charts, image cropping, rotation, motion animation, and other functions on a webpage, if you need a map of China, you can refer to the lat

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 interface implementation class l

This is an experiment that I did when I first came into contact with the Google map API last year. I didn't do any further work in the future, but I wrote a draft and kept it in my blog post. Although some ideas are naive, there are even some errors. Today it seems that there are still some reference values, so I will release the draft for you to have a look. The original text is as follows: 0. Description After some time of thinking, I recently t
