java gui if statment help

[jumpman8947]

I'm finishing up my code to my java program and its basically going to read questions from the array, ask user for the answer(a, b, c, or d). Then I'm going to make it calculate number wrong and right. I'm stuck on the part where my if statement only displays my else case "wrong". Here's the code thanks

import javax.swing.JOptionPane;
import java.text.DecimalFormat;

/**
	This program is a guiquiz
*/

public class GuiQuiz
{
	public static void main(String[] args)
	{


		String[] questions = { "What is science", "How many piers", "What is economics",
			"What year is columbus" };

		JOptionPane.showInputDialog(null, questions[0] + "\nA" + " metal," + "\nB. An art, \nC, Blue. \nD.Rockets");

			if(questions[0].equalsIgnoreCase("a"))
			{
				System.out.println("Correct");

			}
			else
			{
				JOptionPane.showMessageDialog(null, "WRONG");

			}

PS I am going to make another array with the correct answers so it can be easier calculating but, I want the first answer to be a but no matter what I put even a I get "WRONG"

Hello,

In your program you are comparing the content of questions array at index 0 to see if it is equals to "a". The questions[0] has a string of "What is science". This string will never equals to the string "a", that's why it always execute the else part of the if statement.

To get the real answer from the user input you have to read the return value returned by the JOptionPane.showInputDialog() method.

You should capture the input from JOptionPane in a String variable:

String answer = JOptionPane.showInputDialog(...);
//answer will be null if the user cancelled the dialog
if ( answer != null) { 
   if ( answer.equalsIgnoreCase( answers[0]) ) {
       //correct answer found in the answers array
   }
   else {
      ...
   }
}

See: JOptionPane (Java Platform SE 7 )
