JOptionPane showInputDialog incompatible types

I want an Input dialog from JOptionpane
I have the following code:
String anss=JOptionPane.showInputDialog(win,mes,tit,JOptionPane.QUESTION_MESSAGE,new ImageIcon(""),opts,"0");
[\code]
win is a JFrame
mes and tit are Strings
opts is a String array
I get an incompatible types, object found, string required error, jbuilder is underling win red.
I simply have no idea what is happening here.
Does anybody have an idea?

  • Incompatible types - found java.lang.String but expected int

    This is an extremely small simple program but i keep getting an "incompatible types - found java.lang.String but expected int" error and dont understand why. Im still pretty new to Java so it might just be something stupid im over looking...
    import java.io.*;
    import javax.swing.*;
    import java.awt.event.*;
    import java.awt.*;
    public class Lab
    public static void main(String []args)
    int input = JOptionPane.showInputDialog("Input Decimal ");
    String bin = Integer.toBinaryString(input);
    String hex = Integer.toHexString(input);
    System.out.println("Decimal= " + input + '\n' + "Binary= " + bin + '\n' + "Hexadecimal " + hex);
    }

    You should always post the full, exact error message.
    Your error message probably says that the error occurred on something like line #10, the JOptionPane line. The error is telling you that the compiler found a String value, but an int value was expected.
    If you go to the API docs for JOptionPane, it will tell you what value type is returned for showInputDialog(). The value type is String. But you are trying to assign that value to an int. You can't do that.
    You will need to assign the showInputDialog() value to a String variable. Then use Integer.parseInt(the_string) to convert to an int value.

  • JOptionPane.showInputDialog and Focus

    I have a program that allows the user to type in a String in a text box and when they hit the enter key the text will appear in a text area. I've also added a menu bar to the program. When the user clicks on File and then Connect from the menu bar I want a JOptionPane to pop up that asks for the user to type in a username and then prompt for a password. And I've gotten all of that to work. Now for the problem. I click on file from the menu bar and then connect and it prompts me for the username as it should. I am able to just type in a phrase in the text field of the username dialog box and hit the enter key and then it prompts me for my password. I am still able to type in a phrase in the text field of the password Dialog box, however when I hit the enter key, the Dialog box does not close as it did for the username Dialog box. It will still close if I click on the OK button, but just pressing the enter key does not close the Dialog box as it did when it prompted for a username. I'm thinking I need to direct the focus to the password dialog box, but not sure how to go about doing this. Any help in solving this problem would be greatly appreciated.
    Here is my code:
    import javax.swing.*;
    import java.awt.*;
    import java.awt.event.*;
    class TestJOptionPane extends JFrame implements ActionListener{
         private static int borderwidth = 570;
         private static int borderheight = 500;
         private JPanel p1 = new JPanel();
         private JMenu m1 = new JMenu("File");
         private JMenuBar mb1 = new JMenuBar();
         private JTextArea ta1 = new JTextArea("");
         private JTextField tf1 =new JTextField();
         private Container pane;
         private static String s1, username, password;
         private JMenuItem [] mia1 = {new JMenuItem("Connect"),new JMenuItem("DisConnect"),
              new JMenuItem("New..."), new JMenuItem ("Open..."), new JMenuItem ("Save"),
              new JMenuItem ("Save As..."), new JMenuItem ("Exit")};
    public TestJOptionPane (){
         pane = this.getContentPane();
              addWindowListener(new WindowAdapter() {
                   public void windowClosing(WindowEvent e) {
         dispose();
    System.exit(0);
         setJMenuBar(mb1);
    mb1.add(m1);
    for(int j=0; j<mia1.length; j++){
         m1.add(mia1[j]);
    p1.setLayout( new BorderLayout(0,0));
    setSize(borderwidth, borderheight);
    pane.add(p1);
              p1.add(tf1, BorderLayout.NORTH);
              p1.add(ta1, BorderLayout.CENTER);
              this.show();
              tf1.addActionListener(this);
              for(int j=0; j<mia1.length; j++){
                   mia1[j].addActionListener(this);
         public void actionPerformed(ActionEvent e){
              Object source = e.getSource();
              if(source.equals(mia1 [0])){
                   username = JOptionPane.showInputDialog(pane, "Username");
                   password = JOptionPane.showInputDialog(pane, "Password");
              if(source.equals(tf1)){
                   s1=tf1.getText();
                   ta1.append(s1+"\n");
                   s1="";
                   tf1.setText("");
         public static void main(String args[]){
              TestJOptionPane test= new TestJOptionPane();
    }

    But using JOptionPane doesn't get the focus when you call itworks ok like this
    import javax.swing.*;
    import java.awt.event.*;
    class Testing
      public Testing()
        final JPasswordField pwd = new JPasswordField(10);
        ActionListener al = new ActionListener(){
          public void actionPerformed(ActionEvent ae){
            pwd.requestFocusInWindow();}};
        javax.swing.Timer timer = new javax.swing.Timer(250,al);
        timer.setRepeats(false);
        timer.start();
        int action = JOptionPane.showConfirmDialog(null, pwd,"Enter Password",JOptionPane.OK_CANCEL_OPTION);
        if(action < 0)JOptionPane.showMessageDialog(null,"Cancel, X or escape key selected");
        else JOptionPane.showMessageDialog(null,"Your password is "+new String(pwd.getPassword()));
        System.exit(0);
      public static void main(String args[]){new Testing();}
    }

  • Help with JOptionPane.showInputDialog

    Hi!!
    People here helped me before so trying my luck again:)
    In order to get information from people I use JOptionPane.showInputdialog,
    problem is if I need to get 2 different types of info I have to use
            naam = JOptionPane.showInputDialog(null, "Geef speler naam:");
            land = JOptionPane.showInputDialog(null, "Geef Land Speler:");Is there anyway to make this happen in 1 screen?
    Or do I have to make a new frame for that with textfields and such?
    if so, anyone got an example?

    im new here:) so.. New to Java Technology suits me
    well I guess.No it doesn't. New to Java forum is for classpath questions, simple compile time problems and lazy students to cross post their assigments into.
    Swing questions, such as the one you asked, should be asked in the Swing forum because the people who answer questions in there are more knowledgeable about Swing. Plus you will almost 100% likely to find working example codes from previous posts in the Swing forum for Swing related questions.
    Much more likely than in here anyway.

  • Strange problem with JOptionPane.showInputDialog

    I have a strange problem with JOptionPane.showInputDialog in that when I run a program anything that is typed in is displayed backwards, for example: I type this character > and this < is what is displayed.
    I've uninstalled the sdk and reinstalled it twice but that hasn't solved my problem and the java plug-in in the control panel is displaying the same symptoms.
    I did a search before posting this but all I got really was posts from people who wanted to reverse their text.
    Thanks for your help on this.

    Is it just the < and > characters?

  • JOptionPane.showInputDialog Help!!!!

    Hello,
    I'm using JOptionPane.showInputDialog(Component parentComponent,
    Object message,
    String title,
    int messageType,
    Icon icon,
    Object[] selectionValues,
    Object initialSelectionValue ).
    which prompts the user to add some text and the same will be stored for later retrieval.
    In this case, JOptionPane pops up with a label, textfield,OK & Cancel buttons.
    Default focus is given to to the TextField.
    Is there anyway to get access to the TextField via code ?
    For example, if the user types "Hello World" in the given TextField, then I need to get the Text entered in
    the TextField in the following manner.
    String myStr = myJOptionPaneTextField().getText();
    System.out.println("Entered Text is "+ myStr);
    How can I Achieve the same ?
    Thanks in advance
    Regards
    vargav

    Why? At what point do you know you should manipulate the text? Usually, it would be when the user clicks OK, at which point it doesn't matter because the dialog is dismissed. So what kind of operations do you expect to be able to do?
    Aside from that, I'm not sure how to get the text field in the option pane, per se... It can be gotten by digging thru the pane's components til you find a text field. But you'd need to do that in a separate thread. So it's not really feasible to do that.... There is an alternative:
    The message is an object, and it can be an array of objects, which will all be added, and thus can include a message string and a text field...
    JTextField myfield = new JTextField();
    Object[] obj = new Object[2];
    obj[0] = "Enter some text here:";
    obj[1] = myfield;
    if(JOptionPane.showOptionDialog(obj, "Enter Text", JOptionPane.OK_CANCEL_OPTION) == JOptionPane.OK_OPTION) {
       String value = myfield.getText();
    }Then you can do whatever you want with the text field... but the same problem is there, you have lost the dialog before you can do anything.

  • How to customize JOptionPane.showInputDialog?

    Is there a way to change the text on the ok- and cancel buttons in the JOptionPane.showInputDialog()?
    I'm trying to make the input dialog display Norwegian text in the OK and Cancel buttons, but it seems impossible...?
    None of the JOptionPane.showInputDialog methods take the options-array as input, and none of the JOptionPane constructors let me create a input dialog.
    Does anyone know how this can be done, or do I have to write my own InputDialog?

    You can get a partial list of the properties from the UIDefaults Hashtable returned by UIManager.getDefaults(), but for the rest you have to look at the source code. For example, I got this from the source code of BasicOptionPaneUI.          } else if (type == JOptionPane.OK_CANCEL_OPTION) {
                        defaultOptions = new ButtonFactory[2];
                        defaultOptions[0] = new ButtonFactory(
                            UIManager.getString("OptionPane.okButtonText",l),
                            getMnemonic("OptionPane.okButtonMnemonic", l),
                            (Icon)DefaultLookup.get(optionPane, this,
                                              "OptionPane.okIcon"), minimumWidth);
                        defaultOptions[1] = new ButtonFactory(
                            UIManager.getString("OptionPane.cancelButtonText",l),
                            getMnemonic("OptionPane.cancelButtonMnemonic", l),
                            (Icon)DefaultLookup.get(optionPane, this,
                                              "OptionPane.cancelIcon"), minimumWidth);db

  • Incompatible types with generics problem

    Hi,

    Note that the type parameter T used to define class B is not the T used to define class A. What you wrote can be more clearly written:
    class Supply<T extends Supply<T>>{}
    class Store<T extends Supply<T>>{ }
    class A<T extends Supply<T>>{
        private Store<T> store;
        class B<U extends Supply<U>> {
            public Store<U> getStore(){
                return store;
    }Which produces the more readable error message:
    A.java:10: incompatible types
    found   : Store<T>
    required: Store<U>
                return store;B, being a nested, non-static class is already parameterized by T:
    class Supply<T extends Supply<T>>{}
    class Store<T extends Supply<T>>{ }
    class A<T extends Supply<T>>{
        private Store<T> store;
        class B {
            public Store<T> getStore(){
                return store;
