Convert from char to ASCII code

Question

anyone can advice me on this program why the conversion cannot be done? Thank in advance.
String charInput = JOptionPane.showInputDialog (null, "Enter a character", "Finding ASCII code", JOptionPane.QUESTION_MESSAGE) ;
answer = Integer.parseInt (charInput) ;

Answer 1

Try this code out:
import javax.swing.JOptionPane;
public class Crap {
    public static void main (String[] args) {
        String charInput =
                JOptionPane.showInputDialog (null,
                "Enter a character", "Finding ASCII code",
                JOptionPane.QUESTION_MESSAGE) ;
        JOptionPane.showMessageDialog (null, charInput, "Collected Data",
                JOptionPane.INFORMATION_MESSAGE );
//        answer = Integer.parseInt (charInput) ; //<-- What datatype?
        String answer = "You never declare the data type for you answer.\n" +
                "JOptionPane returns a string of what the user enters.\n" +
                "The first?  The last? Some other position?\n" +
                "A String != a character.\n" +
                "Which character of the string do you want to convert?\n" +
                "You need to do a lot more work on this problem.";
        JOptionPane.showMessageDialog (null, answer,
                "The Java Compiler hates your code because...",
                JOptionPane.OK_OPTION, null);
