Will this be like multiple choice where each button is associated with a possible answer, or will the player have to enter (type) in the correct answer? Of course, multiple choice would be much easier to code. Do you want to use the JOptionPane class or Actor objects for your text box and buttons?

yes the player is giving 3 different options there only one of them are the right answer. and if i pick the right one then the main actor will move closer to the goal. but if he don't get a correct answer when it's game over. i am not familiar whit JOptionPlane so i think that actor objects will be the save way to go thank you for the response

The world class should then have a method to 'pose' a question. It would create a Question actor to display the question and create an array of Button actors for the options. You will need an instance Actor field to hold the correct button actor. Keep it 'null' when a question is not being posed so the world act method can know when not to check for a button click. It would be asking something like this:
?

if (correctButton != null && Greenfoot.mouseClicked(Button.class))
{
    if (Greenfoot.mouseClicked(correctButton))
    {
        removeObjects(getObjects(Question.class));
        removeObjects(getObjects(Button.class));
        mainActor.move(1);
        correctButton = null;
    }
    else
    {
        Greenfoot.stop();
        // any other game over actions
    }
}

You only need one Question class and one Button class. Use a double String array to hold the all the String objects:
?
1
2
String[][] problems = { { "Q 1", "Opt 1", "Opt 2", "Opt 3" },
                        { "Q 2", "Opt 1", "Opt 2", "Opt 3" } /** etc. */  };
and an int array to hold the answers:
?
1
int[] answers = { 3, 1 /** etc. */ };
The above fields can be static and final as they will be constants. Next, you will need an int field to hold the index of the current problem. The world will choose a valid index value, create one Question actor to display the question and the three Button actors to display the options. When creating the button that displays the correct answer, set the 'correctButton' field to that button.

First, it is the world that will be creating controlling the questioning and the moving of the MoveingMan object; so, move the act method from the MoveingMan class to the world class (and remove 'getWorld' from the 'addObject' line). Next, I do not see where you declare the 'correctAnswer' field in the world class. Add the following at line 13:
?
1
private Actor correctAnswer;
Now, you do not want to be able to create multiple Questing_1 objects at the same time. So, we need another condition on the 'z' pressing 'if' in the act method. Use
?
1
if (correctAnswer == null && Greenfoot.isKeyDown("z"))
Finally, within the 'if' block, you will need to also add the buttons and set 'correctActor' to the appropriate one (unless some of that is done during the construction of the new Questing_1 object). You may want to post the Questing_1 class for further help.

One more thing -- lines 25 through 39 in your world class should be inside the act method of that class.

At the moment, you have no need to import 'java.util.List' or 'java.awt.Color' into the 'world' class. Remove lines 2 and 3. Also, you are not using the 'background' field anywhere in the 'world' class. So, remove line 12. Now, you only move a line or two of what I said to move to the 'act' method of the 'world' class. You need to move everything between 24 and 42, inclusive, into the 'act' method. Question: what is pressing the 'v' key supposed to do? or maybe I should ask, what is the buttomEorror class creating and what is the purpose of that actor?
