Java中的字字符计数器，带源代码 _Java字符计数器

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

【Java中的字字符计数器，带源代码】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(); }}
