Question

Please see below pseudocode method. If the call to readUrls() throws an exception, doesn t that mean that closeConnection() will not be executed and program flow will return to the method that calls getdata()?

增编

getdata() throws Exception
{
     setup();
     readUrls();
     closeConnection();
}

Answer 1

你的假设是正确的。避免这种情况:

getdata() throws Exception
{
    setup();
    try { 
        readUrls();
    } finally {
        closeConnection();
    }
}

Answer 2

是的,如果readUrls(>> ,则该流程将恢复使用getdata())”这一方法,届时将发生相同的情况,直至:




there is a catch block, where the exception is handled
the exception bubbles up to the main method / to the run method of the thread.

Answer 3

当一个例外被推翻时,现行方法被打断,立即返回。 (最后报表中Connection)

Answer 4

It depends if you have not handled exception in readUrls() then Yes what you are saying is correct. That means you do not have try...catch in readUrls() method.
