Can I do a program in which, if I touch an object, a question arises and I write the answer and if it is right to go on?

Use the 'ask' method of the World class when the object is touched. The method will hold everything until a response is given. Then compare the response, if not null, to the correct answer before proceeding.

And if I would not want to stop while responding. I can do that?sorry ... I want to defend my question and I give an answer, and stop when I write the correct answer ... how should this look like code?
Maybe there is misunderstanding here. How about a little more info! You ask a question; if answer is correct, stop what, exactly? if answer is wrong, what? -- attempt another answer? Please state each step possible scenario, step by step.
if the answer is correct / wrong to erase that bar that appears when you call Greenfoot.ask and keep the answer
The ask bar will go away as soon as the response is given. The answer can be assigned to a local variable or saved in a field:
String response = Greenfoot.ask("What the question is?");
if (response != null && "answer".equals(response))
{
// correct
}
else
{
// wrong or not answered
