How to use Java program instead of Notepad++ word processing and Powershell
This article is about how to use Java programs instead of Notepad++ word processing and Powershell. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
As the word processing in Notepad++ is a little complicated, I wonder if it can be handled uniformly with a Java program.
After a try, I found that it was not too complicated, and it was really convenient for Java to deal with all kinds of things. The procedure is as follows:
Note that in RegExp, four backslashes must be used to represent one backslash.
Package com.pwc;import java.io.BufferedReader;import java.io.ByteArrayOutputStream;import java.io.DataInputStream;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.net.URL;import java.util.ArrayList;import java.util.regex.Matcher;import java.util.regex.Pattern;public class WechatMomentDownload {public static String jsonFile = "C:\\ Download\\ exported_sns_gary.json" Public static String outputFolder = "C:\\ Download\\ gary_pic\"; public static void main (String [] args) throws IOException {BufferedReader reader = null; String sLine = ""; String sContent = ""; String sLink = ""; URL url = null; String outputFile = ""; ArrayList aLink = new ArrayList () String Regex1 = "CDATA\\ [http\:\ /\ / (sh)? mmsns ([^]] *)\\ / 0\\]; reader = new BufferedReader (new InputStreamReader (new FileInputStream (new File (jsonFile))," UTF-8 ")) If (reader! = null) {while ((sLine = reader.readLine ())! = null) {sContent = sContent + sLine;} reader.close ();} Pattern pattern = Pattern.compile (Regex1); Matcher matcher = pattern.matcher (sContent); int count = 0 System.out.println ("Start processing..."); while (matcher.find ()) {count++; sLink = sContent.substring (matcher.start () + 6, matcher.end ()-1); sLink = sLink.replaceAll ("\\ /", "/"); aLink.add (sLink) } System.out.println (count + "pictures were found"); for (String sLinkTemp: aLink) {url = new URL (sLinkTemp); DataInputStream dataInputStream = new DataInputStream (url.openStream ()); outputFile = outputFolder + count + ".jpg"; FileOutputStream fileOutputStream = new FileOutputStream (new File (outputFile)) ByteArrayOutputStream output = new ByteArrayOutputStream (); System.out.println ("Downloading" + sLinkTemp + "to file" + outputFile); byte [] buffer = new byte [1024]; int length; while ((length = dataInputStream.read (buffer)) > 0) {output.write (buffer, 0, length) } fileOutputStream.write (output.toByteArray ()); dataInputStream.close (); fileOutputStream.close (); count--;} System.out.println ("End of processing...");}} Thank you for reading!
