Question

write a program in Java that computes the number of words in a text entered in a text field. Use the following graphical objects:

   •   a text field for the input text (one line of text)

   •   labels to output the word count

   •   a button that, when pressed, computes the word count

   •   a button that, when pressed, clears the text field

   •   a panel, that includes all graphical objects listed above

Make your application run in a window (JFrame) and use a proper layout, backgrounds and colors to make all objects clearly visible.

Extra credit (maximum 2 points) will be given for additional text statistics (for example, maximum, minimum and average word size, number of numeric tokens.

Explanation / Answer

import java.awt.*;         // Using AWT containers and components

import javax.swing.*;

import java.awt.event.*;   // Using AWT events and listener interfaces

public class AWTCounter extends Frame implements ActionListener

{

   private JLabel lblCount;     // declare component Label

   private JTextField tfCount; // declare component TextField

   private JButton btnCount;    // declare component Button

   private int count = 0;      // counter's value

   public AWTCounter ()

{

      setLayout(new FlowLayout());

      lblCount = new JLabel("Counter"); // allocate Label instance

      add(lblCount);                   // "this" Frame adds Label

      tfCount = new JTextField(count + "", 10); // allocate

      tfCount.setEditable(false);       // read-only

      add(tfCount);                     // "this" Frame adds tfCount

      btnCount = new Button("Count");   // allocate Button instance

      add(btnCount);                    // "this" Frame adds btnCount

      btnCount.addActionListener(this);

      setSize(250, 100);       // "this" Frame sets initial size

      setTitle("AWT Counter"); // "this" Frame sets title

      setVisible(true);        // show "this" Frame

   }

   @Override

   public void actionPerformed(ActionEvent evt)

{

      ++count;                     // incrase the counter value

      tfCount.setText(count + ""); // display on the TextField

                                   // setText() takes a String

   }

   public static void main(String[] args)

{

      new AWTCounter();

   }

}
