Thread: String.split"char"; error

i am scanning in lines from a document. i want to store each section of the line into seperate strings variables. each section of the line is seperated by ",". the problem is if there is a space in the variable i gett an arrayOutOfBounds exception for example
...,hello world,yousuck,
here ,hello world, will throw exception where as ,yousuck, would be fine.
so i am assuming it is spliting at space allso as System.out.println prints them on seperate lines im not really sure why it is causing error any help would be great thanks.

here is code

String in=x.nextLine();
String[] tokens = in.split("\\,");
String one=tokens[0];
String two=tokens[1];

What is the exception being thrown? And what is the code to which it refers?

sorry the scanner loads the linies of a text doc into an arraylist
each line is two string seperated by","
code uses selinium
example.. htp://www.google.com,gofish
htp://www.google.com,go fish

for(int u=0;u<sitesL.size();u++){
                    String in=sitesL.get(u);
                    String[] tokens = in.split("\\,");
                    String one=tokens[0];
                    String two=tokens[1];//line throws error
                    WebDriver targetSite=new FirefoxDriver();
                    targetSite.manage().window().setPosition(posg);
                    targetSite.manage().window().setSize(sizeg);
                    targetSite.get(one);//gos to google
                    WebElement target = targetSite.findElement(By.className(classname));//finds search
                    target.sendKeys( two);enters text

here the first line will work fine but the second will throw excption

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
	at chat.Chat.disher(Chat.java:81)//this is line with              String two=tokens[1];
	at chat.Chat.main(Chat.java:37)//this is call from main
BUILD STOPPED (total time: 1 minute 18 seconds)

however it still enters text to search correctly google will search go fish correclty the programe then just throws error

What is the string u that is being split? Print it, along with the length and the contents of the array. Perhaps u does not have the value you think ("htp://www.google.com,gofish" and "htp://www.google.com,go fish")

split("\\,") does split the string on commas as can be seen by removing the other logic and looking merely at what split() does.

public class SplitEg {
    public static void main(String[] args) {
        test("htp://www.google.com,gofish");
        test("htp://www.google.com,go fish");
    }
 
    private static void test(String str) {
        System.out.printf("Looking at -->%s<--%n", str);
        String[] arr = str.split("\\,");
        System.out.printf("Found %d elements:%n", arr.length);
        for(int i = 0; i < arr.length; i++) {
            System.out.printf("    -->%s<--%n", arr[i]);
        }
    }
}
