Explanation / Answer

Please run the below program:

import java.awt.*;
import java.awt.event.*;

public class AwtControlDemo {

private Frame mainFrame;
private Label headerLabel;
private Label statusLabel;
private Panel controlPanel;
private Panel controlPanel1;
private Panel controlPanel2;
private Panel controlPanel3;
CheckboxGroup sortingGrp = null;
CheckboxGroup InputGrp = null;

public AwtControlDemo(){
prepareGUI();
}

public static void main(String[] args){
AwtControlDemo awtControlDemo = new AwtControlDemo();
awtControlDemo.showButtonDemo();
}

private void prepareGUI(){
mainFrame = new Frame("Examples");
mainFrame.setSize(200,400);
mainFrame.setLayout(new GridLayout(3,1));
mainFrame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent windowEvent){
System.exit(0);
}
});
headerLabel = new Label();
headerLabel.setAlignment(Label.CENTER);
statusLabel = new Label();
statusLabel.setAlignment(Label.CENTER);
statusLabel.setSize(150,100);

controlPanel = new Panel();
controlPanel.setLayout(new FlowLayout());

  
mainFrame.add(headerLabel);
mainFrame.add(controlPanel);
mainFrame.add(statusLabel);
mainFrame.setVisible(true);
}

private void showButtonDemo(){
headerLabel.setText("Sorting Algorithm");
//create group
sortingGrp = new CheckboxGroup();
InputGrp = new CheckboxGroup();

//create checkboxes and add to group
Checkbox selection = new Checkbox("Selection", sortingGrp, true);
Checkbox bubble = new Checkbox("Bubble", sortingGrp, false);
Checkbox insertion = new Checkbox("Insertion", sortingGrp, false);
Checkbox quick = new Checkbox("Quick", sortingGrp, false);
  
headerLabel.setText("Sorting Algorithm");
//create checkboxes and add to group
Checkbox alreadysorted = new Checkbox("Already Sorted", InputGrp, true);
Checkbox reverseOrder = new Checkbox("Reverse Order", InputGrp, false);
Checkbox random = new Checkbox("Random", InputGrp, false);
  
Button goButton = new Button("GO");

Label inputSizeLabel = new Label("Input size");
TextField inputSize = new TextField(20);
  
Label blockSizeLabel = new Label("Block size");
TextField blockSize = new TextField(20);

goButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
statusLabel.setText("Go Button clicked.");
}
});

controlPanel1 = new Panel();
controlPanel1.setLayout(new FlowLayout());
controlPanel2 = new Panel();
controlPanel2.setLayout(new FlowLayout());
controlPanel3 = new Panel();
controlPanel3.setLayout(new FlowLayout());

controlPanel.add(selection);
controlPanel.add(bubble);
controlPanel.add(insertion);
controlPanel.add(quick);
  
controlPanel1.add(alreadysorted);
controlPanel1.add(reverseOrder);
controlPanel1.add(random);
  
controlPanel2.add(inputSizeLabel);
controlPanel2.add(inputSize);
controlPanel2.add(blockSizeLabel);
controlPanel2.add(blockSize);

  
controlPanel3.add(goButton);
mainFrame.add(controlPanel1);
mainFrame.add(controlPanel2);
mainFrame.add(controlPanel3);
mainFrame.setVisible(true);
}
}
