    Default Division by Zero

    Hello everybody ,

    I was messing around with java and when I tried to divide a double(decimal) number by 0 ; it was giving me a Infinity response ; does anyone know how to override that infinity response so it can output something like " Why did u just divide by 0 Try Again " . I think it has something to do with the arithmetic expression like so .

    catch(ArithmeticException e)
            {
            System.out.println(beep)
           return " Why did u just divide by 0 Try Again ";
     
                }
    but It is not outputing that message someone has a solution ?

    Also I don't really know it is more of a question or a "what's wrong with my code " so let me know if i am in the wrong section

    Thanks

    Can you post the full text of the error message you get when you divide by 0?

    What you will have to do is check if the divisor is zero then throw the exception.

    Thanks for your response
    I do not get a error message as a response I get "infinity" but I want to be able to write my own response instead of the default one

    Is that a euphemism?

    That provides us zero information. Without context we have no idea what is wrong. As it is that code should work but without the surrounding code and examples of input we have no idea what the problem is.

    I got it figured out :
    I created a class called MydivisionException; and
    if (divisor == 0) throw new MyDivisionException("Why did u just divide by 0 Try Again ");
    Thanks for your help

    The only difference between that and the previous snippet is the use of a different class. If the last snippet didn't work then this should also not work. You must have changed something else in the code which you will not show.

    The MyDivisionByZeroException I created
    public class MyDivisionByZeroException  extends Exception {
     
    	    public MyDivisionByZeroException(String strMessage)
    	    {
    	    	super (strMessage);
    	    }
    }

    and this is what i have in my main program

    if (divisor==0) throw new MyDivisionByZeroException(Why did u just divide by 0 Try Again);

    That's not really enough code to judge what's going on. How are you using divisor? Where is that if statement? It would be very helpful if you could provide an SSCCE that demonstrates exactly what's going on.

    Once again a single line of code is meaningless. It is the surrounding code and how you use that line which is important.
