CompletableFuture not found

October 29, 2022

error:

Java: cannot access java.util.concurrent.CompletableFuture class file for java.util.concurrent.CompletableFuture not found

Imported the library using Maven. Here is the code to start the program:

import org.telegram.telegrambots.meta.TelegramBotsApi;
import org.telegram.telegrambots.meta.exceptions.TelegramApiException;
import org.telegram.telegrambots.updatesreceivers.DefaultBotSession;

public class Main {
    public static void main (String [] args) {
        try {
            TelegramBotsApi botsApi = new TelegramBotsApi(DefaultBotSession.class);
            botsApi.registerBot(new telegaBot());
        } catch (TelegramApiException e) {
            e.printStackTrace();
        }
    }
}

>Solution :

Maybe you use the old java you are trying to run. If you run through the IDE, check with which version of the java IDE you are trying to run. Requires java 8 or higher version

IDE -> ctrl+alt+shift+s -> SDK

try to up jdk version
