Stuck!!!

[neo_31591]

hey guys/...am stuck at one point....help me please! ! !

its a quiz progg... one ques...4 options...

i have one button---NEXT QUES--- It should display the next ques--it should also take the user selected option, compare it with the correct option and show if the Answer is right or wrong

else if(ae.getSource()==b1)
{

if(answer==Answercheck.correct) // checking if answer is correct or not
{
System.out.println("YOUR ANSWER IS CORRECT");
}
else
{
System.out.println("YOUR ANSWER IS WRONG");
}



if(option1.isSelected())
{
System.out.println("Option 1");
answer = option1.getText();
System.out.println(" User Selected ANSWER IS : : : :  "+answer);
}
else if(option2.isSelected())
{
System.out.println("Option 2");
answer = option2.getText();
System.out.println(" User Selected ANSWER IS : : : :  "+answer);
}
else if(option3.isSelected())
{
System.out.println("Option 3");
answer = option3.getText();
System.out.println(" User Selected ANSWER IS : : : :  "+answer);
}
else if(option4.isSelected())
{
System.out.println("Option 4");
answer = option4.getText();
System.out.println(" User Selected ANSWER IS : : : :  "+answer);
}


v1=v1+1;//next ques from database
displayQuestion(v1);//gets the ques from the database and the options also

Answercheck.check(v1); // this only gets the correct answer!!



}
}

also..

v1=0;
so when i run the progg...no ques is displayed..only after i click on b1, is the first question displayed.....

i guess only the order of things is wrong...help me plzzzz!!!

Well then, display one (or fire an event programettically. Really, the "initial" display never comes as the result of an action event, so, if you want a question displayed right away, than you need to display one, and not only display them in the Action Listener (which won't, obviously, be accessed until an Action Event is fired).

[neo_31591]

what i want is the answer to be validated...

when i run my progg i get WRONG ANSWER everytime! ! !

[masijade]

Well, that's not what you said

so when i run the progg...no ques is displayed..only after i click on b1, is the first question displayed.....

CORRECT ANSWER IS Sun
YOUR ANSWER IS WRONG

[masijade]

Do not use == ( if(answer==Answercheck.correct) ) to compare Strings use the equals method
