public class sun.net.www.protocol.http.HttpURLConnection extends java.net.HttpURLConnectionabstract public class HttpURLConnection extends URLConnection
class, а не с расширением java. И откуда в моем коде вообще нарисовались классы от sun?
В ошибке написано "ИсключениеВводаВывода: сервер вернул код http-статуса 503". Код 503 - это ошибка на стороне сервера "сервис недоступен".Это понятно, что надо изменить код программы, чтобы она заработала. Непонятно другое: почему когда в результате выполнения программы:
java.io.IOException: Server returned HTTP response code: 503 for URL: http://ipv4.google.com/sorry/index?continue=http://translate.google.com/translate_tts%3Fie%3DUTF-8%26tl%3Den%26q%3DHello%2Bdear%2Bfriends&q=EgRbegWvGJ3FldEFIhkA8aeDS952qU94sbK8DAgP55pH8cbMicZdMgFy

GoogleTextToSpeech.class или на Main.class в Navigator в Eclipse, то увидим тоже самое:
;; в конце какой-то переменной в системных переменных?
path в system variables стоит такая строчка (с двумя ;)C:\Program Files\Broadcom\Broadcom 802.11;;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;; ?
C:\Program Files\Java\jdk1.8.0_152%JAVA_HOME%%JAVA_HOME%\jre.;%JAVA_HOME%\lib;%JAVA_HOME%\jre\libyour-unique-entries;%JAVA_HOME%\binC:\ProgramData\Oracle\Java\javapath;. I anecdotally noticed that the links in that directory didn't get updated during an JDK installation update. So it's best to remove C:\ProgramData\Oracle\Java\javapath; from the Path system environment variable in order to have a consistent environment.
