Are you importing the "java.io.Console;" and making an instance of that class? like: 

Console console = System.console();

So that you can use the variable "console" to print in a formatted way, if not that may be the problem.

I hope that helps you a little bit.

For BlueJ IDE, instead of "console.printf()", you can use "System.out.printf()" or "System.out.println()".

In my opinion those are much easier and have fewer problems than using a Console object.

Yea. But what can I do in stead of console.readLine().

Also: WHY is console not working in bluej?

You didn't post any source code, so it is impossible for us to see what you are doing wrong.

Another way to get input from the console is the use a Reader:

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class MyClass {
  ...
  BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
  String input = br.readLine();
  System.out.println("You typed into the console: " + input);
  ...
}
