    here the code,

    // Demonstrate URLConnection. 
    import java.net.*; 
    import java.io.*; 
    import java.util.Date; 
     
    class UCDemo 
    { 
    public static void main(String args[]) throws Exception { 
    int c; 
    URL hp = new URL("http", "www.google.com", 80, "/"); 
    System.out.print(hp);
    URLConnection hpCon = hp.openConnection(); 
    System.out.println("Date: " + new Date(hpCon.getDate())); 
    System.out.println("Content-Type: " + 
    hpCon.getContentType()); 
    System.out.println("Expires: " + hpCon.getExpiration()); 
    System.out.println("Last-Modified: " + 
    new Date(hpCon.getLastModified())); 
    int len = hpCon.getContentLength(); 
    System.out.println("Content-Length: " + len); 
    if (len > 0) { 
    System.out.println("=== Content ==="); 
    InputStream input = hpCon.getInputStream(); 
    int i = len; 
    while (((c = input.read()) != -1) && (-i > 0)) { 
    System.out.print((char) c); 
    } 
    input.close(); 
    } else { 
    System.out.println("No Content Available");
