I found this question while Googling  Note that if you just want to make use of the URI s content via something like a string  consider using Apache s IOUtils toString   method   For example  a sample line of code could be   String pageContent   IOUtils toString  http   maps google at maps saddr 4714 amp daddr Marchtrenk amp hl de   Charset UTF 8

If you just want to open up the webpage  I think less is more in this case   import java awt Desktop  import java net URI    Note this is URI  not URL  class BrowseURL      public static void main String args    throws Exception             Create Desktop object         Desktop d Desktop getDesktop                Browse a URL  say google com         d browse new URI  http   google com

Are you sure using the java net URL class  Check your import statements

It works for me  Please check if you are using the right imports   import java io BufferedReader  import java io InputStream  import java io InputStreamReader  import java net URL

Following code should work      URL url   new URL  http   maps google at maps saddr 4714 amp daddr Marchtrenk amp hl de    InputStream is   url openConnection   getInputStream     BufferedReader reader   new BufferedReader  new InputStreamReader  is        String line   null  while    line   reader readLine        null         System out println line     reader close

It may be more useful to use a http client library like such as this  There are more things like access denied   document moved etc to handle when dealing with http    though  it is unlikely in this case
