how do i post code

its too long

[night quest]

split it in two messages?

[gusty swallow]

isnt there a site

to format it all quickly

[night quest]

or only post the relevant parts

[heady oxide]

Please format your code & make it more readable.
For the java programming language, it should look like this:

```java
public class Main{
public static void main(String[] args){
System.out.println("Hello World!");
}
}```
• These are backticks, not quotes.

 public static void main(String[] args) throws FileNotFoundException {
        Scanner file = new Scanner(new File("/Users/michaelbalogun/Desktop/Lab11/src/main/java/applicant_data.csv"));
        ArrayList<candidate> applicants = new ArrayList<>();

        DecimalFormat round = new DecimalFormat("#.##");

        while (file.hasNextLine()) {
            String line = file.nextLine();
            String[] candidates = line.split(",");
            if (candidates.length >= 9) {
                try {

                    candidate c = new candidate(candidates[0], candidates[1], candidates[2], candidates[3], candidates[4], candidates[5], candidates[6], candidates[7],
                            Double.parseDouble(candidates[8]), candidates[9], candidates[10]);
                    applicants.add(c);
                } catch (NumberFormatException e) {
                }
            }

        }

        ArrayList<candidate> finalists = new ArrayList<>();
        for (candidate c : applicants) {
            String s1 = c.languages.toLowerCase();
            if (s1.contains("java")) {
                finalists.add(c);
            }
        }

        Collections.sort(finalists);
        System.out.println("The list of top 10 selected Java students are: ");
        for (int i = 0; i < Math.min(10, finalists.size()); i++) {
            System.out.println(finalists.get(i));
        }
    }

System.out.println(finalists.get(i));

wont print

Can you print finalists.size() before the loop?

Does that work?

It looks like you are having issues with debugging or issues that can be solved using a debugger.
Check out this article on dev.java to see how debugging works and how to use a debugger.
This Stack Overflow question and its answers also explain debugging in general.

These links describe how to use the debugger in some IDEs:
• Debugging in IntelliJ
• Debugging in Eclipse

size is 0

not to sure why

i thoughti added to it

[strange birch]

Well it's better to check than to think

You should display information at all stages, was the split correct, are the fields where they're expected, is "java" there where expected...

Ideally with a debugger, but you can make do with whatever you know in the beginning

[gusty swallow]

trying to trace right now

after tracing thorugh

the error has to come from

[gusty swallow]

for soem reason my applicants gets added to

but i cant add to my finalists

 ArrayList<candidate> finalists = new ArrayList<>();
        for (candidate x : applicants) {
            String lang = x.languages.toLowerCase();
            if (lang.contains("java")) {
                finalists.add(x);
            }
        }

        Collections.sort(finalists);
        System.out.println(finalists.size());
        System.out.println("The list of top 10 selected Java students are: ");
        for (int i = 0; i < Math.min(10, finalists.size()); i++) {
            System.out.println(finalists.get(i));
        }
    }

[night quest]

maybe none of the languages contain java?
