嵌入html文件中的java小應(yīng)用程序運行出錯,html文件如下：
<HTML>
<BODY>
<APPLET CODE="Example5_9.class" WIDTH="300" HEIGHT="100">
</APPLET>
</BODY>
</HTML>
Example5_9的代碼如下：
package test;
import java.util.*;import java.applet.*; import java.awt.*;
import javax.swing.*;import java.awt.event.*;
public class Example5_9 extends Applet implements ActionListener{
JTextArea textA; JTextField textF; JButton b1,b2;
public void init(){
setSize(250,150);
textA=new JTextArea("",5,10);
textA.setBackground(Color.cyan);
textF=new JTextField("",10);
textF.setBackground(Color.pink);
b1=new JButton("求 和");b2=new JButton("重新開始");
textF.setEditable(false);
b1.addActionListener(this);b2.addActionListener(this);
add(textA);add(textF);add(b1);add(b2);
}
public void actionPerformed(ActionEvent e){
if(e.getSource()==b1){
String s=textA.getText();
StringTokenizer tokens=new StringTokenizer(s);
int n=tokens.countTokens(),sum=0,i;
for(i=0;i<=n-1;i++){
String temp=tokens.nextToken();
sum +=Integer.parseInt(temp);
}
textF.setText(""+sum);
}
else if(e.getSource()==b2){
textA.setText(null);
textF.setText(null);
}
}
}
錯誤信息如下：
