Data acquisition based on Java (I)

Previously, I wrote 2 articles on PHP data collection and warehousing:

In fact, the principle of collection is the same: remote access to information - > extract the required content (regular) - > classified storage - > read - > display

It doesn't matter what programming language you use. Programming language is just a tool

This time, let's collect data from a football website: http://www.footballresults.org/league.php?league=EngDiv1

The following figure shows the data we want to collect:

OK, let's look at the above two articles on the acquisition principle. The rest are directly related to the code:

GerData. Java (data collection method encapsulation)

In fact, it is a simple matching rule:

Group (): returns the input subsequence captured by the given group during the previous matching operation.

Find (): attempts to find the next subsequence of the input sequence that matches the pattern.

 1 package com.lcw.curl;

CurlMain. Java (main program)

Inputstreamreader () is a bridge between byte flow and character flow.

Inputstreamreader () is a bridge between byte flow and character flow.

Openstream () opens the connection to this URL and returns a byte stream for reading from the connection.

Data collection is easy, and the effect is shown in the figure below:
