How to fix “java.lang.IndexOutOfBoundsException: Index: 1, Size: 1” problem

Question

I am trying to iterate the elements , where i have to get text body for every element, but after 1st element body is printed, next for next element body I am getting "java.lang.IndexOutOfBoundsException: Index: 1, Size: 1". I know this is very simple fix, but i am unable to fix it. Please help me to fix this issue.

In my below code, when "String text = KpiText.get(i).getText();" prints for 2nd time i am getting "java.lang.IndexOutOfBoundsException: Index: 1, Size: 1" error.

public void checkKPIValuesForTeam() throws InterruptedException{


        List<WebElement> userNames = DifferentUsers.findElements(By.xpath("//div[@class='radio sfa-radio-red']"));
        System.out.println(userNames.size());

       int maxLength = userNames.size();

       for(int i=0;i<maxLength;i++){

        WebElement namesOfUsers = userNames.get(i);
        System.out.println(namesOfUsers);
        namesOfUsers.click();

        List<WebElement> KpiText = KPIValues.findElements(By.xpath("//*[@id='main-content-app']/div/div[2]/div/div/div[2]/div[2]/div[1]/div/div[1]"));
        System.out.println(KpiText.size());
        String text = KpiText.get(i).getText();
        System.out.println(text);

}

Expected is it should print the body for all the elements for iteration.

Answer 1

The problem is very simple. You are using the value "i" to access the "KpiText" array. In this case, your array has only one element, so the index 1 is out of bounds, as the exception stack trace says.

If you want to print them all you should do this:

for (WebElement element : KpiText)
   System.out.println(element.getText());

Answer 2

It seems that usernames.size() is greater than the size of KpiText. When referencing the KpiText List make sure the index is actually there. So maybe a check like

if(i < KpiText.size()){
 String text = ...
}

Answer 3

If you are iterating over List<WebElement> KpiText it is better idea to do it like this :

   List<WebElement> KpiText = KPIValues.findElements(By.xpath("//*[@id='main-content-app']/div/div[2]/div/div/div[2]/div[2]/div[1]/div/div[1]"));

   for(int i=0; i < KpiText.size() - 1; i++){

    WebElement namesOfUsers = userNames.get(i);
    System.out.println(namesOfUsers);
    namesOfUsers.click();

    System.out.println();
    String text = KpiText.get(i).getText();
    System.out.println(text);
}
