Java net URL

A URL is a unique address to an Internet resource. Here is a URL: http://www.rntsoft.com:80/index.htm HTTP: the protocol to use to retrieve the resource. http://www.yahoo.com/: the host, where the resource resides. 80 is the port number. /index.htm specifies the path of the URL. In Java, a URL is represented by a java.net.URL object. public URL (java.lang.String spec) public URL (java.lang.String protocol, java.lang.String host,java.lang.String file) public URL (java.lang.String protocol, java.lang.String host,int port, java.lang.String file) public URL (URL context, String spec) URL myUrl = new URL ("http://www.rntsoft.com/"); Because no page is specified, the default page is assumed. The following lines of code create identical URL objects. URL yahool = new URL ("http://www.yahoo.com/index.html"); URL yahoo2 = new URL ("http://www.yahoo.com", "/index.html"); URL yahoo3 = new URL ("http://www.yahoo.com", 80, "/index.html");
