Hey!, i'm writting this piece of code.
In it when i receive the string packet for carnivore and parse i will use some little pieces as variables.
I get this error:
Error while running applet.
java.lang.ArrayIndexOutOfBoundsException: 1
at Temporary_1383_4679.loop(Temporary_1383_4679.java:37)
at BApplet.nextFrame(BApplet.java:49
at BApplet.run(BApplet.java:42
at java.lang.Thread.run(Thread.java:536)
when compile my code. Any one can help me?
Here's my code:
//code:
//for p5 69
//
/////carnivore
Socket socket;
BufferedReader packetreader;
CarnivoreListener CL;
String packet;
String packet_datestamp;
////////mis variables
String cut;
int ipDe1;
int ipDe2;
int ipDe3;
int ipPara1;
int ipPara2;
int ipPara3;
int puerto1;
int puerto2;
void setup(){
//start listening to carnivore
CL = new CarnivoreListener();
CL.startListening();
}
void loop(){
packet = CL.getPacket();
String lista[] = split (packet,'.');
///////// ip de
ipDe1 = Integer.parseInt(lista[1]);
ipDe2 = Integer.parseInt(lista[2]);
ipDe3 = Integer.parseInt(lista[3]);
//////// ip para
String ip6 [] = split(lista[6]);
ipPara1 = Integer.parseInt(ip6[2]);
ipPara2 = Integer.parseInt(lista[7]);
ipPara3 = Integer.parseInt(lista[8]);
/////// puerto de
puerto1 = Integer.parseInt(ip6[0]);
String p2 [] = split(lista[10]);
puerto2 = Integer.parseInt(p2[0]);

Hola,
You must have in mind that arrays indexes go from 0 to the (length of the array)-1.
I see that in your code, you are not using lista[0]. I don't know if that is in purpose or not, but if the lista[] array has 10 elements lista[10] will give you an OutOfBounds errors.
This might not be the error, in that case, an example of the value of the variable 'packet' could help in solving the problem.
Espero que te sirva de ayuda,
ricard

let me add to ricards post, you can check if lista is set and what size it has like this:
Code:if (lista != null && lista.length >= 10)
{
/*ok*/
}
