I think you should probably look at the basics of Java if you don't understand this snippet.

At a glance, you will have to first construct it:

private final GrandExchange ge = new GrandExchange();

... and then call it's methods, e.g:

int sellingPrice = ge.getSellingPrice(995);

 

lol, the api dead anyhow
