Baidu Map SDK not only for the vast number of developers to provide a cool map display effect, rich overlay layer, more developers to provide a variety of LBS search capabilities. Through these interfaces, developers can easily access Baidu's LBS data, enrich their mobile-end map applications. The current Baidu map SD

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 Li

The list supports quick inserts and deletions, but it takes time to find them; Vector supports fast lookups, but inserts take time. The time complexity of the map lookup is logarithmic, which is almost the fastest, and the hash is logarithmic.If I wrote it myself, I would also use a binary search tree, it can guarantee logarithmic complexity in most cases, the worst-case scenario is constant complexity, and

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

Use Echarts to show cities in the series section of the map if you return data with JSON, JS cannot be used directly with strings. Need to deal with it.The data returned by some JSON in PHP　　JS to get the JSON information with AJAX implementation callBecause the format of the display city in the Echarts chart map is [{name: ' Beijing '},{name: ' Tianjin '}] first

It took about a week or more for the city modeling plug-in to be made, and there were some flaws, but it had already achieved the desired effect. The first thing to say is that there is absolutely no commercial purpose to do this, just hope to achieve this goal in the Houdini to master more programmatic thinking.First look at the effect:Map Resources:Map Links: https://www.openstreetmap.orgAbout the map XML
