guys when you ask questions please mention all the details.coz there are many ways to do any kinda job in java..
The Swing toolkit includes a rich set of components for building GUIs and adding interactivity to Java applications. Swing includes all the components you would expect from a modern toolkit: table controls, list controls, tree controls, buttons, and labels.
modern days we use IDEs for this.
hope this will help you

machan simple inheritance and polymorphism is used there.its a small problem.
gmme tha question. (i wanna know how to implement tha display method)
man kiwwe barcode eken number ekak text field ekakata ganna hati witarai bro. api ewidiyata register mark up project ekak kara. n it worked
your problem is not clear, i mean you have not mentioned weather a constructors are used or not. so i implemented methods for all
public class Customer {
int cusNo;
String name;
String address;
double salesValue;
public void setData(int pcusNO,String pname,String paddress,int psalesValue){
cusNo=pcusNO;
name=pname;
address=paddress;
salesValue=psalesValue;
}
public void display(){
System.out.println("name is:" +name+" cusNO is: "+cusNo+" address is: "+address+"salesvalues are:"+salesValue);
}
}
class RegularCustomer extends Customer{
double discount;
double amountPayable;
public void setData(int pcusNO,String pname,String paddress,int psalesValue,double pdiscount){
super.setData(pcusNO, pname, paddress, psalesValue);
discount=pdiscount;
}
public void calculateAmountPayable(double TOTAL){
amountPayable=TOTAL-discount;
}
public void display(){
super.display();
System.out.println("Discount is "+discount+" Amount payable is "+amountPayable);
}
}

Not lyk this machan....
This is the senario...
When user press "Add new field" button a new field must be dynamically added to the current form. This is little bit complex. Have to mplement in JFrame form. Not in applet. If u can help me.
this not complex at all machan
heres the codin,
(im doing with t with a button, and button is on ma jframe)
this is tha main class(compile this)
//------------------------------------------------------------------------
public class JavaApplication12 {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
NewJFrame nw=new NewJFrame();
nw.setVisible(true);
// TODO code application logic here
}
}
//--------------------------------------------------------------------
Now i have implemented 2 buttons in ma jframe
one button is used to hide the jtextfield and from other button you can view it
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
NewJFrame.jTextField1.setVisible(false);
// TODO add your handling code here:
}
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
try{
jTextField1.setVisible(true);
}
catch (Exception e){
}
// TODO add your handling code here:
}
this is tha basic idea of your software. Now you can edit it lik this
add a panel to tha jframe and add jtextfield and button on to that
goto panels customized code(write click on t and select customize code)
and add jbutton 2s coding there
now when you compile your main program jframe comesup!
but not the textfield coz its visibility is off via tha panel.
so only when user clicks on the button its visibilty is on.
HOPE YOU GT THA IDEA!
IF U STILL CANT GET IT POST HERE ILL SEND YOU MA APPLICATION FOLDER
