Word Character Counter in Java with Source Code

Word Character Counter in Java with Source Code: We can develop Word Character Counter in java with the help of string, AWT/Swing with event handling. Let's see the code of creating Word Character Counter in java.

1. String text="hello javatpoint this is wcc tool";  
2. String words[]=text.split("\\s");  
3. int length=words.length;//returns total number of words  
4. int clength=text.length();//returns total number of characters with space  

Let's see the swing code to count word and character.

1. import java.awt.event.*;  
2. import javax.swing.*;  
3. public class WCC extends JFrame implements ActionListener{  
4. JTextArea ta;  
5. JButton b1,b2;  
6. WCC(){  
7.     super("Word Character Counter - JavaTpoint");  
8.     ta=new JTextArea();  
9.     ta.setBounds(50,50,300,200);  
10.       
11.     b1=new JButton("Word");  
12.     b1.setBounds(50,300,100,30);  
13.       
14.     b2=new JButton("Character");  
15.     b2.setBounds(180,300,100,30);  
16.       
17.     b1.addActionListener(this);  
18.     b2.addActionListener(this);  
19.     add(b1);add(b2);add(ta);  
20.     setSize(400,400);  
21.     setLayout(null);  
22.     setVisible(true);  
23. }  
24. public void actionPerformed(ActionEvent e){  
25.     String text=ta.getText();  
26.     if(e.getSource()==b1){  
27.         String words[]=text.split("\\s");  
28.         JOptionPane.showMessageDialog(this,"Total words: "+words.length);  
29.     }  
30.     if(e.getSource()==b2){  
31.         JOptionPane.showMessageDialog(this,"Total Characters with space: "+text.length());  
32.     }  
33. }  
34. public static void main(String[] args) {  
35.     new WCC();  
36. }  
37. }
