4 errors, probably need to import or define something

[cc11rocks]

I am making a GUI. I just have four simple errors (that i probably need to import something for). I am using two files, "Risk.java" and "RiskApp.java".
Risk.java:

import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.JLabel;
import javax.swing.text.*;
import java.text.NumberFormat;

public class Risk extends JPanel {
    int leftNumber = 0;
    int rightNumber = 0;
    public JButton enter;
public JTextField stupid, yummy;
public JLabel smart, dumb;
public NumberFormat sucker;
public NumberFormat lucker;
    public Risk() {
JLabel smart = new JLabel("First Number:");
add(smart);
JTextField sucker = new JTextField(nucker);
add(sucker);
boolean isDigit;
JLabel dumb = new JLabel("Second Number:");
add(dumb);
JTextField lucker = new JTextField(yucker);
add(lucker);
        enter = new JButton("Enter");
        add(enter);
	
    }
private void setUpFormats() {
yucker = NumberFormat.getNumberInstance();
nucker = NumberFormat.getNumberInstance();
}
}

RiskApp.java:

import javax.swing.*;        

public class RiskApp {
    private static void createAndShowGUI() {
        JFrame frame = new JFrame("Risk");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        Risk riskPanel = new Risk();
        frame.getContentPane().add(riskPanel);

        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}

The errors I am getting are:

Risk.java:19: cannot find symbol
symbol: variable nucker
location: class Risk
JTextField sucker = new JText Field(nucker);

the carrot (i'm using Cmd Promp) is pointed to the "n" in "nucker"
Another error:

Risk.java:24: cannot find symbol
symbol: yucker
location: class Risk
JTextField lucker = new JText Field(yucker);

the carrot is pointed to the "y" in "yucker"
Another error:

Risk.java:31: cannot find symbol
symbol : variable yucker
location: class Risk
yucker = NumberFormat.getNumberInstance();

The carrot is pointed to the "y" in "yucker"
And finally:

Risk.java:32: cannot find symbol
symbol : variable nucker
location: class Risk
nucker = NumberFormat.getNumberInstance();

With the Carrot pointed to the "n" in "nucker"
If you know how to fix these errors please show and/or tell me how.
Thank you very much,

Perhaps I am missing it but I do not see where you declared nucker and yucker, I only see you assigning them.

[cc11rocks]

What do I declare them to be?
Thanks,
cc11rocks

[sunde887]

Im not quite sure, what do you intend for them to be?

[cc11rocks]

private void setUpFormats() {
yucker = NumberFormat.getNumberInstance();
nucker = NumberFormat.getNumberInstance();
}
}

[sunde887]

NumberFormat (Java 2 Platform SE v1.4.2)

Looks like you want

NumberFormat yucker = NumberFormat.getNumberInstance();

Here is the new risk with the new errors:
Risk.java:

import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.JLabel;
import javax.swing.text.*;
import java.text.NumberFormat;

public class Risk extends JPanel {
    int leftNumber = 0;
    int rightNumber = 0;
    public JButton enter;
public JTextField stupid, yummy;
public JLabel smart, dumb;
NumberFormat yucker = NumberFormat.getNumberInstance();
NumberFormat nucker = NumberFormat.getNumberInstance();
    public Risk() {
JLabel smart = new JLabel("First Number:");
add(smart);
JTextField sucker = new JTextField(nucker);
add(sucker);
boolean isDigit;
JLabel dumb = new JLabel("Second Number:");
add(dumb);
JTextField lucker = new JTextField(yucker);
add(lucker);
        enter = new JButton("Enter");
        add(enter);
	
    }
}

New errors created (old ones fixed):

Risk.java:19: cannot find symbol
symbol : constructer JTextField(java.text.NumberFormat)
location: class javax.swing.JTextField
JTextField sucker = new JTextField(nucker);

the carrot is pointed towards the "n" in "new"

Risk.java:24: cannot find symbol
symbol : constructor JTextField(java.text.NumberFormat)
location: class javax.swing.JTextField
JTextField lucker = new JTextField(yucker);

the carrot is pointed towards the "n" in "new"
Thanks for your help,

Why are you setting the number formats up in a private method but not calling it? What is the point of this method? Also, not to be rude, but, are you trying to figure this out yourself before posting? Take some time and think about the error. If after 30-40 minutes you can't figure it out, come here. You won't learn if we tell you what to fix. There are some other weird things in this code that you should take a minute to think about

in the beginning you declare

public NumberFormat sucker;
public NumberFormat lucker;

Then in the constructor you say

JTextField sucker = new JTextField(nucker);
JTextField lucker = new JTextField(yucker);

I'm onto something. I got it to run, but I need to make the JFormattedTextField to have multiple columns, not 0. Here is the working code that I suspect works, but I can't test it until I have multiple columns. i tried to add columns, but it return the errors when i try to.
Risk.java:

import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.JFormattedTextField;
import javax.swing.JLabel;
import java.text.NumberFormat;

public class Risk extends JPanel {
    public JButton enter;
public JFormattedTextField stupid, yummy;
public JLabel smart, dumb;
public NumberFormat yucker = NumberFormat.getNumberInstance();
public NumberFormat nucker = NumberFormat.getNumberInstance();
    public Risk() {
JLabel smart = new JLabel("First Number:");
add(smart);
JFormattedTextField stupid = new JFormattedTextField(yucker);
add(stupid);
boolean isDigit;
JLabel dumb = new JLabel("Second Number:");
add(dumb);
JFormattedTextField yummy = new JFormattedTextField(nucker);
add(yummy);
        enter = new JButton("Enter");
        add(enter);
	
    }
}

RiskApp.java is the same.
I get the same errors when i try to add the number 2 to :

JFormattedTextField yummy = new JFormattedTextField(yucker);

so it would look like:

JFormattedTextField yummy = new JFormattedTextField(yucker, 2);

and it'll display those 2 errors i had earlier.
Could you please help me with these?
Thanks,

JFormattedTextField inherits the setColumns() method of JTextField. Try that.

Keep the API docs open in your browser because you can't guess at what a method or constructor will do.

Thank you so much. It works perfectly now. For anyone who wants to see my working code, here it is:
Risk.java

import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.JFormattedTextField;
import javax.swing.JLabel;
import java.text.NumberFormat;

public class Risk extends JPanel {
    public JButton enter;
public JFormattedTextField stupid, yummy;
public JLabel smart, dumb;
public NumberFormat yucker = NumberFormat.getNumberInstance();
public NumberFormat nucker = NumberFormat.getNumberInstance();
    public Risk() {
JLabel smart = new JLabel("First Number:");
add(smart);
JFormattedTextField stupid = new JFormattedTextField(yucker);
stupid.setColumns(3);
add(stupid);
boolean isDigit;
JLabel dumb = new JLabel("Second Number:");
add(dumb);
JFormattedTextField yummy = new JFormattedTextField(nucker);
yummy.setColumns(3);
add(yummy);
        enter = new JButton("Enter");
        add(enter);
	
    }
}

and here is RiskApp.java

import javax.swing.*;
import java.text.NumberFormat;    

public class RiskApp {
    private static void createAndShowGUI() {
        JFrame frame = new JFrame("Risk");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Risk riskPanel = new Risk();
        frame.getContentPane().add(riskPanel);
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {

                createAndShowGUI();
            }
        });
    }
}

Now I have to work on the "enter" button and everything. Expect to see me in the Swing/AWT forum to figure out that.
Thanks to everyone who helped. I really appreshiate it. I do have one question. What API book thing were you talking about? I know what the API is, but I don't have an API book so what do I do?
Thanks to everyone,
