panel that has calc which can be re-sized

[joe'g]

hi am trying to code a program that uses a panel that has a functional calculator in it, and the calculator can be re-sized using a slider.
here is my code
please help me out

import javax.swing.*;
import javax.swing.event.*;
import java.awt.*;
import java.awt.event.*;

public class CalcInSlider extends JPanel{
    JSlider slider;
    JLabel label;
    private JPanel MasterFieldP, calcPanel;
    private JLabel Tx;
    Container c;
    private JButton buttons[]; //array of buttons
    private final String names[]={"7","8","9","/","*","4","5","6","+","-","1","2","3","=",",","0","."}; 



  public static void main(String[] args){
    CreateSlider cs = new CreateSlider();
    Calculator calc=new Calculator();
        calc.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  }

  public CalcInSlider(){
    JFrame frame = new JFrame("Slider Frame");
    slider = new JSlider();
    slider.setValue(70);
    slider.addChangeListener(new MyChangeAction());
    label = new JLabel("Calclator");
    JPanel panel = new JPanel();
    panel.add(slider);
    panel.add(label);
    frame.add(panel, BorderLayout.WEST);
    frame.setSize(400, 400);
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  }

   Calculator() {
        super ("Calculator");
        c=getContentPane();

        MasterFieldP=new JPanel();
        Tx=new JLabel("0");
        Tx.setHorizontalTextPosition(JLabel.LEFT);
        Tx.setBackground(Color.WHITE);
        Tx.setOpaque(true);
        getContentPane().add(Tx, BorderLayout.NORTH);

        calcPanel=new JPanel();
        buttons=new JButton[names.length];//create array of JButtons
        calcPanel.setLayout(new GridLayout(4,4,5,5));

        for (int count=0;count<names.length;count++)
            {
                buttons[count]=new JButton(names[count]);
                buttons[count].addActionListener(this);//register Listener
                calcPanel.add(buttons[count]);//add button to JFrame
            }

            MasterFieldP.setLayout(new BorderLayout());
            MasterFieldP.add(calcPanel,BorderLayout.SOUTH);
            getContentPane().add(MasterFieldP,BorderLayout.SOUTH);


            setSize(300,200);//set frame size
            setVisible(true);//display frame
    }//end class Calculator

  public class MyChangeAction implements ChangeListener{
    public void stateChanged(ChangeEvent ce){
      int value = slider.getValue();
      String str = Integer.toString(value);
      label.setText(str);
    }
  }

}//end class CalcInSlider

Can you describe your problem? What does the program do that you don't like or what do you want the program to do that it does not do?
