计算文本区域中的单词数

Question

大家好我关于堆栈溢出的第一个问题

import javax.swing.*;
import java.util.*;
import java.awt.event.*;

public class TI extends JFrame implements ActionListener
{
static int count=0;
String ct;
JTextField word;
JTextArea tohide;
public static void main(String arg[])
{
    TI ti=new TI();
}

public TI()
{

    JPanel j=new JPanel();
    JLabel def=new JLabel("Enter the text to be encrypted");
    word=new JTextField("",20);
    tohide=new JTextArea("",5,20);
    JButton jb=new JButton("COUNT");
    tohide.setBorder(BorderFactory.createLoweredBevelBorder());
    j.add(def);
    j.add(tohide);
    j.add(word);
    j.add(jb);
    add(j);
    setSize(500,500);
    setVisible(true);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setLocationRelativeTo(null);
    jb.addActionListener(this);

}

public void actionPerformed(ActionEvent ae)
{

    String txt=tohide.getText();
    StringTokenizer stk=new StringTokenizer(txt," ");
    while(stk.hasMoreTokens())
    {
        String token=stk.nextToken();
        count++;
    }
    ct=Integer.toString(count);;
    word.setText(ct);

   }

    }

我想计算textarea中输入的单词数.这是一个逻辑错误.当我一直点击计数按钮时,字数会增加.

Answer 1

count在重新计算单词数之前,您永远不会将重置为0.似乎不需要count成为类变量.做出这种改变会使这种错误变得不可能.
