Eclipse and IntelliJ have issues with java.io.Console. You need to use System.in and System.out instead. System.out works virtually the same as Console for output but for input you need to open a BufferedReader first:

BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
System.out.printf("Make a guess: ");
String guess = bufferedReader.readLine();
