  2. Use toString () to convert a Uri to a String. Use Uri.parse () to convert a String to a Uri. this code doesn't work That is not a valid string representation of a Uri
  3. Java URL toString () Method The toString () method of URL class constructs a string representation of this URL. The string is created by calling the toExternalFile () method of the stream protocol handler for this object

In the following code shows how to use URL.toString () method. import java.net.URL; //from w w w.j a v a2 s .c o m public class Main { public static void main (String [] argv) throws Exception { URL url = new URL (http://java2s.com:80/index.html); System.out.println (url.toString ()); } The toString method returns a URI string with all necessary quotation but which may contain other characters. The toASCIIString method returns a fully quoted and encoded URI string that does not contain any other characters. Identities For any URI u, it is always the case that new URI(u.toString()).equals(u) You can easily encode a URL string or a form parameter into a valid URL format by using the URLEncoder class in Java. This utility class contains static methods for converting a string into the application/x-www-form-urlencoded MIME format. The following example shows how to use the URLEncoder.encode () method to perform URL encoding in Java Java URL toURI() method. The toURI() method returns URI equivalent to given URL. This method functions in the same way as new URI (this.toString()). Synta You should first convert your string into a URI, then convert the URI into a URL. For example: String str = http://google.com; URI uri = new URI(str); URL url = uri.toURL(); Please note, there are 2 unhandled exceptions; so you should wrap the above code within 2 try/catch statements

URI(String str): Constructs a URI object by parsing the specified string. The grammar used while parsing is the one specified in RFC 2396, Appendix A. Syntax :public URI(String str) throws URISyntaxException Parameters : str : String to be parsed into URI Throws : URISyntaxException : If the string violates RFC 239 This post will discuss how to read the contents of a URL into a string in Java. There are several ways to directly read the contents of a URL in plain Java and using third-party Java libraries such as Guava, Apache Commons IO. To read the contents of a URL, the idea is to call the URL's openStream() method, which returns a java.io.InputStream.

Not correct on both counts. It is very common to have multiple parameters with the same name, and the getParameterValues() method gives them to you as an array without the need for dealing with the query string
