Question

I have most of the swing app designed, however, I am having difficulties getting it to the specs. My portion of the swing app is located below the image. Thank you, for your assitance.

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

public class AsciiConversion {

public static void main(String[] args) {
SwingApp app = new SwingApp(250, 150);   // set app window size
app.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}

class SwingApp extends JFrame //"extends"
{
private final JTextField textField1, textField2; //text fields for input
private final DrawPanel panel, panel2;       // class variable

public SwingApp(int width, int height) // class constructor
{
super();               // call to super class constructor
Container pane = super.getContentPane(); // create layout, set colors
panel = new DrawPanel();       // add GUI components
panel2 = new DrawPanel();       // add GUI components
// panel.setBackground(Color.white); // set the color yellow as the background
panel.setLayout(new BorderLayout());
  
panel2.setLayout(new BorderLayout());
  
/*Panel p = new Panel();
p.setLayout(new BorderLayout()); EXAMPLE FOR BORDER LAYOUT
p.add(new Button("Okay"), BorderLayout.SOUTH);*/
//------------------------- add other GUI components to the panel-----------------------------
  
JPanel jp1 = new JPanel(new BorderLayout());
   jp1.add(new JLabel("Character: "), BorderLayout.CENTER);
   textField1 = new JTextField(3); //SETS THE SIZE OF THE TEXT FIELD
  
// JPanel jp3 takes the label "power: " and the corresp. input field
   JPanel jp2 = new JPanel(new BorderLayout());
   jp2.add(new JLabel("ASCII code: "), BorderLayout.WEST);
   textField2 = new JTextField(3); //SETS THE SIZE OF THE TEXT FIELD
   //jp2.add(textField2);
jp2.add(textField2);
  
JPanel jp3 = new JPanel(new FlowLayout(FlowLayout.CENTER));
JPanel jp4 = new JPanel(new FlowLayout(FlowLayout.RIGHT));
  
panel.add(jp1); // add the created panels to the grid layout manager
   panel.add(jp2);
panel.add(jp2);
panel.add(jp3);
panel.add(jp4);

panel.add(pane); // add panel to the main app container
  
Toolkit toolkit = Toolkit.getDefaultToolkit();   // optionally position JFrame
Dimension screenSize = toolkit.getScreenSize(); // puts the popup in the middle of the screen
super.setLocation((screenSize.width - width) / 2, (screenSize.height - height) / 2);
super.setTitle("ASCII CONVERSION");       // set desired window title
super.setSize(width, height);       // set desired window size

Char ASCII Converter Character ASCII code The application has to have the following functionality: o After entering a character into the left text field and pressing the "Enter" button, the ASCII code should appear in the right text field. o If the user enters not a single character, a warning not a character should appear in red color. o After entering an ASCII code in the range [33..126] into the right text field, the corresponding character should appear in the left text field. o If the user enters an integer outside the range 133..126], a warning number out of range should appear in red color. o If the user enters not an integer in the right text field, a warning not a number should appear in red colo o If the conversion is successful, a confirmation should appear in white color. conversion complete o All warnings and notifications should be displayed in the SOUTH layout region. Furthermore, make sure that: o The colors are exactly as it is shown above. The involved colors are: Color blue for the top title string Char ASCII converter Color black for the strings "Character" and "ASCII code" for the involved panels Color green, and Color orange o The application window size is 250x150 pixels. o The the size of the input fields is 1 and 3 characters, respectively. o The ActionListener attached to a JTextField component catches hitting the Enter key event and calls the corresponding method needed to implement this interface. o Use nested panels and GridLayout and BorderLayout layout managers for the inner and outer panels, respectively. o To change the label color use the method setForeground(Color) o To change the panel background use the method setBackground(Color) o Refer to the Java documentation for more info.

Explanation / Answer

g.DrawPanel.setBackground(color.orange);

g.Panel.setBackground(color.green);

g.panel2.setBackground(color.range);

g.drawString("Char <> ASCII converter", 20, 20);

   g= new panel.jframe(“Character                  ASCII code”);
