Question

I have some code that throws a potential error and I catch these, then jump into a finally block, here it is in ‘pseudo’ form.

private boolean myMethod(ResultSet rs1, ResultSet rs2){

Vector<String> temp = new Vector<String>();

try{

//add info into temp while condition is true
while(true){temp.add(information);}//potentially throws an SQL error

//test my temo object for some codition
if(false){throw InternalError();}


}catch (SQLException e){
     //send error message
}
catch (InternalError e){
     //send error message
}

finally{
//whatever happens I need to send a result of some sort!

if(temp.size() > 1){
   //create class member variable from this info
}

//send a message explaining that an error has occurred.

//this is the message to say if things have worked or not, so as the
//calling code can handle an re-run this method until this value returns true.
return booleanValue
}//end finally


}//end method

I’m not sure exactly what this error message means in this instance.

I generally handle any exceptions within any method that throws them, should I in this instance throw rather than handle the Exception, and catch both of the errors in a custom Exception?

The first 2 messages that I send out are mainly for development purposes, and because I have to handle them.
The message in my finally block will ultimately comprise the message to the user, asking them to confirm the situation, make a modification, abort or change how we got to this situation.

What should I do to ‘remove’ the compiler message. I don’t like to suppress warnings in my code as I don’t like the implication that I may suppress something else further down the chain, and also the suppression is for the whole method, I can’t add it in for just this small block of code.

Is there any advice for my situation.

Thanks in advance.

edit1: To reflect comments, sorry forgot to put the correct return type (silly mistake) same this the if(test){} closing brace.

PS. To those that have ‘downvoted’ you could put a comment and give me a chance to edit prior to downvoting. thanks. Also in my code these things aren’t giving me problems, its a case of ‘a quertyscript malfunction’ between brain and fingers during posting.

Answer 1

Method return type is void and you have return statement return booleanValue in your finally block. I would use finally block to close non-java resource.

If you want to return values then either return it in try block or catch block OR outside of try{} catch{} but not in finally{}.
