Building Absolute/Relative URIs

This tip show you how to build absolute/relative URIs by using the java.net.URI methods.

• Building an absolute URI:

  try{   URI uri_absolute=new URI("http://www.java.sun.com/");   URI uri_relative=new URI("index.html");   URI uri_absolute_result=uri_absolute.resolve(uri_relative);   System.out.println(uri_absolute_result);   }catch(URISyntaxException e)               {System.out.println(e.getMessage());}

  The result:

  http://www.java.sun.com/index.html

• Building a relative URI:

  try{   URI uri=new URI("/docs/imagini/mare/");   URI uri_relative=new URI("eforie/discoteca.jpg");          URI uri_relative_result=uri.resolve(uri_relative);   System.out.println(uri_relative_result);   }catch(URISyntaxException e)               {System.out.println(e.getMessage());}

  The result:

  /docs/imagini/mare/eforie/discoteca.jpg

• Building an absolute URI:

  try{   URI uri_absolute=new URI("http://www.java.sun.com/");             URI uri_absolute_result=uri_absolute.resolve("index.html");   System.out.println(uri_absolute_result);            }catch(URISyntaxException e)              {System.out.println(e.getMessage());}

  The result:

  http://www.java.sun.com/index.html

• Building a relative URI:

  try{   URI uri=new URI("/docs/imagini/mare/");             URI uri_relative_result=uri.resolve("eforie/discoteca.jpg");   System.out.println(uri_relative_result);   }catch(URISyntaxException e)               {System.out.println(e.getMessage());}

  The result:

  /docs/imagini/mare/eforie/discoteca.jpg

• Getting a relative URI:

  try{  URI uri_absolute_1=new URI("http://www.java.sun.com/index.html");  URI uri_absolute_2=new URI("http://www.java.sun.com/");               URI uri_relative_result=uri_absolute_2.relativize(uri_absolute_1);   System.out.println(uri_relative_result);            }catch(URISyntaxException e)               {System.out.println(e.getMessage());}

  Result:

  index.html
