Java

The keyword throws indicates that a method might throw an exception.

class URLConnect {
   public String fetchUrl(String url) throws java.io.IOException {
      ...
   }
}

When calling a method that declares a throws statement you can either declare the calling mehtod with throws or you can use a try-catch-finally declaration.

// bubbling the Event upwards
public Object evaluateURL(String url) throws java.io.IOException {
   ...
   String s = urlconnect.fetchUrl(url);
   ...
}

// using try-catch-finally
try {
    ...
    String s = urlconnect.fetchUrl(url);
    ...
} catch (java.io.IOException e) {
   e.printStackTrace();
}
