Java中的字字符计数器，带源代码

Java中带有源代码的Word字符计数器：我们可以借助字符串, 带有事件处理的AWT / Swing开发Java中的Word字符计数器。让我们看看在Java中创建字字符计数器的代码。

String text="hello srcmini 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

让我们看一下用于计算单词和字符的代码。

import java.awt.event.*;
import javax.swing.*;
public class WCC extends JFrame implements ActionListener{
JTextArea ta;
JButton b1, b2;
WCC(){
	super("Word Character Counter - srcmini");
	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();
}
}

带有填充和文本颜色的字数示例

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();
}}
