Java : Code To Download A File From A Website

Thought i'd share some java code this time . The following code would help you to download any file from a website . So you could use this to fetch any information which is in the form of a file from a remote website . It can also be used to download a specific file . With some more coding , you could also schedule it to download at a specific time . So here's the code to download a file from a website in java :

Note : Save the file as filedown.java .. and compile it . To run type java filedown abcd.com/abc.zip .. where abcd.com/abc.zip is the link to the location of the file to be downloaded on the remote website .

import java.io.*;
import java.net.*;
public class filedown {
public static void download(String address, String localFileName) {
OutputStream out = null;
URLConnection conn = null;
InputStream in = null;
try {
URL url = new URL(address);
out = new BufferedOutputStream(
new FileOutputStream(localFileName));
conn = url.openConnection();
in = conn.getInputStream();
byte[] buffer = new byte[1024];
int numRead;
long numWritten = 0;
while ((numRead = in.read(buffer)) != -1) {
out.write(buffer, 0, numRead);
numWritten += numRead;
}
System.out.println(localFileName + "\t" + numWritten);
} catch (Exception exception) {
exception.printStackTrace();
} finally {
try {
if (in != null) {
in.close();
}
if (out != null) {
out.close();
}
} catch (IOException ioe) {
}
}
}

public static void download(String address) {
int lastSlashIndex = address.lastIndexOf('/');
if (lastSlashIndex >= 0 &&
lastSlashIndex < address.length() - 1) {
download(address, address.substring(lastSlashIndex + 1));
} else {
System.err.println("Could not figure out local file name for " +
address);
}
}

public static void main(String[] args) {
for (int i = 0; i < args.length; i++) {
download(args[i]);
}
}
}
