Slicing a list in java

I have a list which I get from the selenium-webdriver: 

List<WebElement> allElements = driver.findElements(By.xpath(""));

Now I want to get the first 6 elements and print them.

A different and concise way to do that is using streams from Java 8:

List<WebElement> subElements = allElements.stream().limit(6).collect(Collectors.toList());

You can use List#sublist():

System.out.println(allElements.subList(0, 6));

Or, since you're using Webdriver, you also have Google Guava (it's a transitive dependency), so Iterables.limit() also works and it's arguably slightly more readable and doesn't fail when the list is too short:

System.out.println(Iterables.limit(allElements, 6));

There are multiple ways and one of them is below:

for(int i=0; i < 6; i++) {
    WebElement element =  allElements.get(i);
    }

Use condition to check the for loop iteration something like, 

int i=1;
for(WebElement element: allElements){
if(i==6)
break; //break the loop
system.out.println(""+element.getText());
i++;
}
