Usage

From source file:GetURL.java

public static void main(String args[]) throws Exception {
    URL url = new URL("http://www.google.com");
    InputStream urlstream = url.openStream();
    byte[] buffer = new byte[0];
    byte[] chunk = new byte[4096];
    int count;/*from   www .j a va 2s .c  o m*/

    while ((count = urlstream.read(chunk)) >= 0) {
        byte[] t = new byte[buffer.length + count];
        System.arraycopy(buffer, 0, t, 0, buffer.length);
        System.arraycopy(chunk, 0, t, buffer.length, count);
        buffer = t;
    }

    String filename = (url.getFile()).replace('/', File.separatorChar);
    File f1 = new File(filename);
    filename = f1.getName();
    FileOutputStream f = null;
    f = new FileOutputStream(filename);
    f.write(buffer);
    f.close();
