If I set references to the table with all of the data to null after pulling the information from it, will it free all allocated memory?

 

map.clear()

 

please.

how often is this updated every 15 minutes?

How do you change for average buy and average sell

How do you change for average buy and average sell

The data is retrieved in the format:

{"overall":369,"buying":372,"buyingQuantity":108551,"selling":367,"sellingQuantity":121543}

Using a URL such as: http://api.rsbuddy.com/grandExchange?a=guidePrice&i=1515

 

 

The following method retrieves the "overall" value:

private Optional<Integer> getRSBuddyPrice(){
    try {
        URL url = new URL("http://api.rsbuddy.com/grandExchange?a=guidePrice&i=" + id);
        URLConnection con = url.openConnection();
        con.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36");
        con.setUseCaches(true);
        BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String json = br.readLine();
        br.close();
        Matcher matcher = Pattern.compile("\"overall\"\\s*:\\s*(\\d*)").matcher(json);
        return matcher.find() ? Optional.of(Integer.parseInt(matcher.group(1))) : Optional.empty();
    } catch(Exception e){
        e.printStackTrace();
    }
    return Optional.empty();
}

If you wanted to retrieve all of these data items, you can just alter this method to instead return a Map<String, Integer>, and instead of just doing:

Matcher matcher = Pattern.compile("\"overall\"\\s*:\\s*(\\d*)").matcher(json);
return matcher.find() ? Optional.of(Integer.parseInt(matcher.group(1))) : Optional.empty();

Which gets the "overall" value, you can do this for "buying", "selling" etc. and add it to the Map.

 

I will write this up when I get home if you aren't sure how to do it.

can you write it up please bro if you could

do i need two different matches

These snippets are wonderful. I was just getting around to writing a fighter and needed to write in my loot calculator. Thanks so much for sharing this.

sigh perhaps you should read up on the Java Garbage Collector then.

 

If you are really concerned about memory usage, then perhaps you should use a profiler to see how much memory, and where the memory is being used.

 

It isn't really a concern though. It's just a Map containing a few objects..

How can i get only price?

Great snippet

Any idea why this worked perfectly for me for a couple of first times and started not to find the items I'm looking for? Even tried by replacing the getRSBuddyPrice() method with getOSRScurrentPrice().

I noticed there was a slight error in one of the regex patterns, it may have been causing issues for you. I have fixed it in the original post.

How can i get only price?

Map<String, ExchangeItem> exchangeItems = new RSExchange().getExchangeItems("Your item");
exchangeItems.get("Your item").getPrice();

Map<String, ExchangeItem> exchangeItems = new RSExchange().getExchangeItems("Your item");
exchangeItems.get("Your item").getPrice();

i got it working long time ago, but anyways thanks.

If I may ask, is there a reason why java.util.Optional is unresolveable? Maybe it's just me?

Make sure the language level of your IDE is set to Java 8, because Optionals were a new feature introduced in Java 8.

Aha, that explains that then. I was still using 1.7.0. Thanks!
