带源代码的 Java 词符计数器

带源代码的 Java 词符计数器：我们可以借助字符串、AWT/Swing 以及事件处理在 Java 中开发词符计数器。让我们看看在 Java 中创建词符计数器的代码。

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

让我们看看统计词数和字符的 Swing 代码。

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();
}
}

带填充和文本颜色的词数统计示例

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class CharCount extends JFrame implements ActionListener{
	JLabel lb1,lb2;
	JTextArea ta;
	JButton b;
	JButton pad,text;
	CharCount(){
		super("Char Word Count Tool - JTP");
		lb1=new JLabel("Characters: ");
		lb1.setBounds(50,50,100,20);
		lb2=new JLabel("Words: ");
		lb2.setBounds(50,80,100,20);
		
		ta=new JTextArea();
		ta.setBounds(50,110,300,200);
		
		b=new JButton("click");
		b.setBounds(50,320, 80,30);//x,y,w,h
		b.addActionListener(this);
	
		pad=new JButton("Pad Color");
		pad.setBounds(140,320, 110,30);//x,y,w,h
		pad.addActionListener(this);

		text=new JButton("Text Color");
		text.setBounds(260,320, 110,30);//x,y,w,h
		text.addActionListener(this);

		add(lb1);add(lb2);add(ta);add(b);add(pad);add(text);
		
		setSize(400,400);
		setLayout(null);//using no layout manager
		setVisible(true);
		setDefaultCloseOperation(EXIT_ON_CLOSE);
	}
	public void actionPerformed(ActionEvent e){
		if(e.getSource()==b){
		String text=ta.getText();
		lb1.setText("Characters: "+text.length());
		String words[]=text.split("\\s");
		lb2.setText("Words: "+words.length);
		}else if(e.getSource()==pad){
			Color c=JColorChooser.showDialog(this,"Choose Color",Color.BLACK);
			ta.setBackground(c);
		}else if(e.getSource()==text){
			Color c=JColorChooser.showDialog(this,"Choose Color",Color.BLACK);
			ta.setForeground(c);
		}
	}
public static void main(String[] args) {
	new CharCount();
}}
