Thread: How do I log exception when it is thrown

Here is the situation. When I throw an exception, I want my wrapper class to pick it up and put it into a database. (For simplicity I am just printing it in this example).
However, when I throw the exception, the constructor for my exception subclass never gets called.

public class SmartHomeXcp extends Exception
{
    private final StackTraceElement trace[]; 
    private int sizeOfTrace;
    public SmartHomeXcp(String message)
    {
        super(message);
        trace = getStackTrace();
        sizeOfTrace = trace.length;
        printSize();
    }
 
    public void printSize()
    {
        System.out.println("Size " + sizeOfTrace);
        for(int i = 0; i < sizeOfTrace; i++)
        System.out.println("Trace: " + trace[0]);
        System.out.println("Did we make it here?");
    }
 
}

public class ExceptionGiver 
{
    public static void causeException()
    {
         throw new SmartHomeXcp("Dude exception here!!!!");
    }
 
    public static void main(String[] args)
    {
        ExceptionGiver.causeException();
    }
}

Oh wow is it a compile error???
I did not even notice that thank you... I thought it was the exception that I was getting in the red letters

when you throw an Exception, I think you should also handle it, it is either you catch it or you throws it beside the method.
example:

public void doExceptions() throws Excetion {
     throw new Exception("balh blah blah");
}

or

public void doException() {
     try {
            throw new Exception("blah blah blah");
     } cathc (Exception e) {
            // do something here
     }
}
