Help-would like JFRAME added to program

[tigerfan2]

I have the following driver and class and would like to add JFRAME to it but have no clue how. Essentially I would like to figure out how to place all "public void Display" in GUI frames instead of the boring defualt dispaly boxes. If not what can I do to dress this program up a little bit. Plus how do you line a text string up so it appears a little neater, see my menu. thanks.

Here is the Driver:
public class Main {
/**
*
*/
public static void main (String[] args) {
/**
* Set up arrays and variables
*/
double unitCost [] = {0.00, 2.50, 100.00, 75.00, 95.00, 15.00, 8.50, 65.00, 45.00, 12.00, 72.00 };
String product [] = { "No item", "BaseBall", "Bat", "Infield Glove", "Catcher's Mit", "Batting Helmet", "Batting Glove", "Uniform with Team Logo", "Uniform without Team Logo", "Hat", "Cleats" };
String custNames [] = new String [6];
int quantityOrdered [] [] = new int [6] [11];
double totalSales [] [] = new double [6] [11];

double totalUnitCost = 0.0, totalCustSale = 0.0; //taxrate = 0.10, tax = 0.0;
int quantity = 0, itemNumber = 0, maxCust = 0, custNumber = 0, maxC = 0, maxProd = 0; //
String company = "Butch's Baseball Supplies", output, input;

maxProd = product.length;
WClass WEF = new WClass();
// Obtain maximum number of Customers to process: call getMaxCust method
do
{
maxCust = WEF.getMaxCust("Enter the number of customers:");
}
while (maxCust< 1 || maxCust >5);


/**
* Obtain the names of Customers to process: call getCustNames method
*/
WEF.getCustNames(custNames, maxCust);

/**
* Use a loop to process each customer in the Customer array
*/

for ( custNumber = 1; custNumber <=maxCust; ++custNumber)
{
do // process do-while for same customer until he enters '0' for item, which is exit
{
itemNumber = WEF.getChoice (custNumber); // Call method to get the item number
if (itemNumber !=0 )
{
quantity = WEF.getQuantity (custNumber, itemNumber, product, custNames, quantityOrdered);
WEF.itemPriceTotal (custNumber, itemNumber, quantityOrdered, unitCost, totalSales);
}

} while (itemNumber !=0);
WEF.displays (custNumber, maxCust, product, custNames, itemNumber, quantityOrdered, unitCost, totalSales);
}

WEF.eodDisplay(maxProd, product, custNames, quantityOrdered, unitCost, totalSales);
}
}

Here is mty working class:
package javaapplication24;
import javax.swing.*;
import java.text.DecimalFormat;

maxC=Integer.parseInt(input);
if (maxC < 1 || maxC > 5)
JOptionPane.showMessageDialog(null, "Invalid Number - choose between 1 and 5 customers");
return maxC;
}
public void getCustNames(String custNames[], int maxC)
{
for (int c=1; c <=maxC; ++c)
{custNames [c]=JOptionPane.showInputDialog("Enter customer #"+c+"'s name:");

About the JFrame.
You can use this format. i just created a simple Structure that can guide you.

import javax.swing.*;
 //Loads the Swing Components which contains the Jframe and others
import java.awt.*; 
//Loads AWT which contains the container and Listener if you like to use buttons

//Global Declarations
       private JLabel A = new Jbutton();

//adding extends & implements enable the use of Jframe and Action Listeners
public class Main extends JFrame implements ActionListener{ 
JFrame Samp = new JFrame();
        Samp.setTitle("This is my Program"); //Set the Title
        Samp.setBounds(100, 100, 800, 600); //(set the location and size)
        Samp.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        Samp.setVisible(true); //This will open your Gui
        Container container = this.getContentPane(); //set a container
        // From this on you can add buttons, textfields, etc to the container
        
       container.setLayout(null); 
       //setting it to null but you can use other layouts on this

       //Example of adding a button
       Jbutton A = new Jbutton("Compute Quantity");
       A.addActionListener(this); //adds a listener
       A.setBounds(x,y,Width,Ht); //This are in pixels, set the location
       container.add(A); // finally adds the button to the container

       //Example of adding a label
       A.setText("Output Here");
       A.addActionListener(this); //adds a listener
       A.setBounds(x,y,Width,Ht); //This are in pixels, set the location
       container.add(A); // finally adds the button to the container
  
       //Add more components here see tutorials for other components =)

}


//Here is were the action listener awaits =)
   public void actionPerformed(ActionEvent event) {
        String command = event.getActionCommand();
    if(command.equalsIgnoreCase("Compute Quantity")){
        //Quantity equation here
        //Display the output to a textfield/Label/TextArea
        A.setText(Output Here); //Change the display of A (Jlabel)
    } else if (command.equalsIgnoreCase("Other buttons")){
    
    } else if (command.equalsIgnoreCase("Other buttons2")){
    
    }

}

}

I hope this Helps. =P
