HEllO EVERY ONE

I need you help in my java code that I built on netbeans

First I will example the idea of the programm

GUI are containing two textfeild
The first textfeild the user have to enter price
The second textfeild the user have to enter weight

then when I click on run botton , the price and weight in label 3,label4

SO I create class apple for price and weight
here is my code for class Apple

package my.NewClass;

/**
 *
 * 
 */
public class AppleClass {

    //Instance variable definition
    private int weight;
    private int price;



    //Method definition
    //Constructor definition
    public NewClass()
    {

        weight = 0;
        price = 0;
    }

    public AppleClass(int a,int b)
    {
        weight = a;
        price = b;
    }

    public AppleClass(String text, String string, int parseInt) {
        throw new UnsupportedOperationException("Not yet implemented");
    }

    //Set/Get definition
    public void Setweight(int a)
    {
        weight  = a;
    }
    public int Getweight()
    {
        return weight;
    }


    public void Setprice(int b)
    {
        price = b;
    }
    public int Getprice()
    {
        return price;
    }

    //Other methods
}

here are my code for GUI where I have the problem:

public class Programming2 extends javax.swing.JFrame {

    /** Creates new form Programming2 */
    public Programming2() {
        initComponents();
    }
AppleClass[] Apple  = new AppleClass[2];
    /** This method is called from within the constructor to
     * initialize the form.

Hello,

After quickly reviewing your code, have you thought about trying to just use the jbutton as the variable button1 + button2 = button3? Not sure if this actually helps, worth a try. If your going to use your apple functions you may want to assign them to a button?

actually I have two button one for caluclate and second for button 2
the caluclate buton will calclate the price in jlabl3
and the weight in jlabel4

DO you use the netbeans ?

Yes, I use Netbeans. I don't have a choice.
