java catching exception and continue execution

Question

I want to catch an exception, print the place the exception occured and continue running the loop. I have this example code:

public class justcheckin {
static String[] l = {"a","a","b","a","a"};

public class notAexception extends Exception{

    private static final long serialVersionUID = 1L;

    notAexception (){
        super();
    }
    notAexception(String message){
        super(message);
    }
}

private  void loop () throws notAexception {
    notAexception b = new notAexception("not an a");
    for (int i = 0; i< l.length; i++){
        if (! l[i].equals("a")){
            throw b;
        }
    }
}

public static void main (String[] args) throws notAexception{
    justcheckin a = new justcheckin();
    a.loop();
}
  }

I want to write a warning message, say "index 2 is not a", and continue running the loop. How can I do it?

Thanks!

just remove the throw b; section and instead write a Logger message. — Runcorn

I think in your code there is no need to have try catch throw etc.

But still in your same code if you want to perform this,

    public class justcheckin {
static String[] l = {"a","a","b","a","a"};

public class notAexception extends Exception{

    private static final long serialVersionUID = 1L;

    notAexception (){
        super();
    }
    notAexception(String message){
        super(message);
    }
}

private  void loop () throws notAexception {
    notAexception b = new notAexception("not an a");
    for (int i = 0; i< l.length; i++){
        try{
            if (! l[i].equals("a")){
                throw b;
            }
        }catch(notAexception ne){
            System.out.println("index "+i+" is not a");//index 2 is not a
        }
    }
}

public static void main (String[] args) throws notAexception{
    justcheckin a = new justcheckin();
    a.loop();
}
  }

thanks a lot! it works. Another newbie question: what is the meaning of "ne" in the 'catchw phrase?

'ne' is just a variable. Just like you took 'justcheckin a'.
