int i = new JFileChooser().showOpenDialog(MDIWebBrowser.this);
if(i==JFileChooser.APPROVE_OPTION){
File f = new JFileChooser().getSelectedFile();
try{
InputStream is=new FileInputStream(f);
new WebBrowserPane().read(is,"");
}catch(Exception ex){
ex.printStackTrace();
}
}
}
}

这是打开一个文件的事件 请教这段代码中read()的用法

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

WebBrowserPane是自己定义的
