Scanner scanner = new Scanner(System.in);
String name = scanner.nextLine();
int number = scanner.nextInt();
System.out.println(name + " will take over the world in " + number + " years. Mwa-ha-ha!");
Doesn't work and I don't know why

Nvm, figured that out, here's the code for everyone strugglin:
package en.javarush.task.jdk13.task03.task0318;
import java.io.BufferedReader;
import java.io.InputStreamReader;
/*
How to take over the world
*/
public class Solution {
public static void main(String[] args) throws Exception {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String name = reader.readLine();
String sNumber = reader.readLine();
int number = Integer.parseInt(sNumber);
System.out.println(name + " will take over the world in " + number + " years. Mwa-ha-ha!");
}
}

you dont even need to parse int from the input text because there is no need in representation of it as a number. System.out.println wants a string, and you can leave it a String, without making unnecessary transformations ;)

well, the first task is definitely not for level 2... It was a poor explanation in the lesson, so there is close to no chance of completing the task without additional research

Did you suddenly forgot that you were teaching people and not just talking to yourself?

I don't understand what does the 'BufferedReader' and 'InputStreamReader' and why should we use them together...

This is a difficult topic. It's like learning English: you just have to remember first.
