Java implements the method of downloading pictures from the Internet to the local

This article illustrates the Java implementation of downloading images from the web to the local method. Share with you for your reference. The details are as follows:

import java.io.*;
import java.net.MalformedURLException;
import java.net.URL;
public static void writeFile(String strUrl,String fileName){
　　URL url = null;
　　try {
　　　　url = new URL(strUrl);
　　} catch (MalformedURLException e2) {
　　　　e2.printStackTrace();
　　}
　　InputStream is = null;
　　try {
　　　　is = url.openStream();
　　} catch (IOException e1) {
　　　　e1.printStackTrace();
　　}
　　OutputStream os = null;
　　File f = new File("d:\webimg\");
　　f.mkdirs();
　　try{
　　　　os = new FileOutputStream("d:\webimg\"+fileName);
　　　　int bytesRead = 0;
　　　　byte[] buffer = new byte[8192];
　　　　while((bytesRead = is.read(buffer,0,8192))!=-1){
　　　　　　os.write(buffer,0,bytesRead);
　　　　}
　　}catch(FileNotFoundException e){
　　} catch (IOException e) {
　　　　e.printStackTrace();
　　}
}
