Using Java code to get element from another page

This is the code that I am using. Can someone tell me what is wrong with it?

String FundsApi = "https://www.rblxrewards.esy.es/api/funds";

Document document = Jsoup.connect(FundsApi).get();

String FundsValue = document.body().get(0).text();
console.warn(FundsValue);
