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.

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

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

import java.awt.event.*;
import javax.swing.*;
public class WCC extends JFrame implements ActionListener{
JTextArea ta;
JButton b1,b2;
WCC(){
	super("Word Character Counter - JavaTpoint");
	ta=new JTextArea();
	ta.setBounds(50,50,300,200);
	
	b1=new JButton("Word");
	b1.setBounds(50,300,100,30);
	
	b2=new JButton("Character");
	b2.setBounds(180,300,100,30);
	
	b1.addActionListener(this);
	b2.addActionListener(this);
	add(b1);add(b2);add(ta);
	setSize(400,400);
	setLayout(null);
	setVisible(true);
}
public void actionPerformed(ActionEvent e){
	String text=ta.getText();
	if(e.getSource()==b1){
		String words[]=text.split("\\s");
		JOptionPane.showMessageDialog(this,"Total words: "+words.length);
	}
	if(e.getSource()==b2){
		JOptionPane.showMessageDialog(this,"Total Characters with space: "+text.length());
	}
}
public static void main(String[] args) {
	new WCC();
}
}

Word Count Example with Pad and Text Color

import java.awt.event.*;
public class CharCount extends JFrame implements ActionListener{
	JLabel lb1,lb2;
	JTextArea ta;
	JButton b;

	}
	public void actionPerformed(ActionEvent e){
