Multithreading in java learning

0x00 Preface

In a tool development, if the tool needs to continuously perform the same action or request, using single thread is very slow. Take a directory scanner as an example. For example, we need to develop a directory scanner. There are 10000 dictionaries in our dictionary, and only one thread initiates HTTP requests. This speed is very slow. However, if we use multiple threads, four threads, and each thread requests 2500 dictionaries, our time can be shortened by four times.
