Hello

I know it's not within the context of the question, but I wanted to write to find out if I'm wrong or not.

In the following code, it appears that the lambda expression is typed incorrectly, is this correct?

Code: Select all

public void invokeService(String srvname, String host, int port){
     ...
     Socket socket = null;
     try{
        AccessController.doPrivileged( ( PrivilegedExceptionAction<Void> ) ()->
               socket = new Socket(host, port);
               return null;
     }
     ...
}

Both lines after the lamda expression belong to the lamda expression? So shouldn't I have a key?

And if this were not the case, if only the first line belongs to the lambda, which I do not think is the case, then the ; at the end of the expression it would not be bad.

Thanks in advance for responding

Yes, an opening and closing brace should be there so that both the line become part of the lambda.

Yes.

Not sure what you mean.
