Explanation / Answer

We have convert your code into GUI. import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.JOptionPane; public class CompString implements ActionListener{ JFrame frame; JPanel panel; JTextField string1; JLabel label1, label2; JButton compareButton; JTextField string2; public CompString() { frame = new JFrame("Compare String"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(new Dimension(180, 80)); panel = new JPanel(new GridLayout(3, 2)); panel.setBorder(BorderFactory.createEmptyBorder(60, 60, 20, 60)); addItems(); frame.getRootPane().setDefaultButton(compareButton); frame.getContentPane().add(panel, BorderLayout.CENTER); frame.pack(); frame.setVisible(true); } private void addItems() { label1 = new JLabel("Text1", SwingConstants.LEFT); string1 = new JTextField(20); compareButton = new JButton("Compare"); label2 = new JLabel("Text2", SwingConstants.LEFT); string2 = new JTextField(20); compareButton.addActionListener(this); panel=new JPanel(new GridLayout(4,1)); panel.add(label1); panel.add(string1); panel.add(label2); panel.add(string2); panel.add(compareButton); label1.setBorder(BorderFactory.createEmptyBorder(5, 10, 5, 5)); label1.setBorder(BorderFactory.createEmptyBorder(5, 10, 5, 5)); } public void actionPerformed(ActionEvent event) { String st1=string1.getText(); String st2=string2.getText(); if (st2.compareTo(st1) > 0){ JOptionPane.showMessageDialog(null,"The second string is greater than the first one"); } else{ JOptionPane.showMessageDialog(null,"The first string is greater than the second one"); } } private static void createAndShowGUI() { JFrame.setDefaultLookAndFeelDecorated(true); CompString converter = new CompString(); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } }
